Leon

"I have fought alongside you many times, there is no one that I would rather die for..."

- Leon to Arthur

Sir Leon is a loyal and trustworthy Knight of Camelot who served under both Uther and Arthur Pendragon. He became a Knight of the Round Table when he joined Arthur in his bid to retake the kingdom from Morgana and her sister Morgause, and soon became one Arthur's most trusted advisors. He is the only Knight of the Round Table (except Gwaine) who is of noble blood.

Early life
Little is known about Leon's early life, only that Gwen and Elyan's mother was once a maid in his family's household (The Coming of Arthur). He was from a family of noble blood, and at some point joined the Knights of Camelot.

As a Knight of Camelot
When Leon allowed Arthur to win a jousting match during training (and possibly did the same in the previous year's tournament), Arthur was greatly annoyed and became determined to prove that he could win without being given preferential treatment. He later defeated Leon in the tournament semi-finals while disguised as Sir William of Deira (The Once and Future Queen).

Leon was one of the knights who helped Arthur gather information on suspected magic users (and people suspected of consorting with magic users) when Uther suspected that someone had attempted to assassinate Morgana (The Nightmare Begins).

When Uther was bewitched by a troll disguised as Lady Catrina, Leon was doubtful of the king's magically influenced decisions and appeared to disapprove of Uther's choice to strip Arthur of his title as Crown Prince. Leon was amongst those who attempted to tell Uther that his new wife was a troll, and had to endure several council meetings with her. During one of these meetings he tried to dissuade the king from introducing further taxes, and advised that they decline Lord Bayard's offer of a visit (Beauty and the Beast).

Leon was amongst the knights who searched Gaius and Merlin's home for magical objects, and was the one who found the magical amulet that Aredian had planted to frame Merlin for sorcery (The Witchfinder).

When Arthur returned to Camelot after his meeting with Morgause, he was enraged at his father after having learned the true circumstances of his birth. Leon was looking over papers with Uther in the council chambers when Arthur arrived, and was instructed to guard the door. As such, he tried to prevent Merlin from entering the chamber, but was eventually persuaded to let him in when Merlin claimed that the king's life was in danger (The Sins of the Father).

When Morgause enchanted Morgana with a spell that made everyone in Camelot fall asleep, Leon was present in Uther's chambers when Gaius examined the king and ordered bedrest, believing him to be ill (The Fires of Idirsholas).

Leon was amongst the knights who defended Camelot when it was attacked by the Great Dragon. He was the first to volunteer to ride out and face the Dragon with Arthur, and was injured by the beast's fiery breath (The Last Dragonlord).

Leon led the border patrol that spotted Cenred's army and reported it to the court. He later fought in the Great Battle for Camelot against Cenred's forces as well as the skeleton soldiers raised by Morgana (The Tears of Uther Pendragon).

Leon was with several other knights in the Rising Sun when Gaius - who had been possessed by a Goblin - insulted Leon and spit beer in his face. Enraged, the knight challenged him to a duel, but the Goblin quickly apologized and offered to buy him and his friends a drink. In light of his years of friendship with Gaius, Leon accepted his apology and forgave him. The next day boils broke out on his and his friends' faces, the result of a magical potion that the Goblin had used to spike their drinks. Desperate, Leon and the other knights went to Gaius for help, and were sold an antidote at an exorbitant price (Goblin's Gold).

During Gwaine's first stay in Camelot, Leon broke up a fight between him and two thugs disguised as knights. After Gwaine was arrested for breaking the knight's code, Leon was present at his trial (Gwaine).

Knight of the Round Table
Leon was a member of the Camelot patrol that was attacked and killed for crossing the border into Cenred's land. The sight of the battle was eventually discovered by a group of Druids, who began searching for survivors and found that Leon was still alive. They took him back to their camp and healed him with water from the Cup of Life. Once recovered, Leon then returned to Camelot and informed Uther of what had happened, prompting the king to send Arthur to retrieve the Cup from the Druids before Cenred could discover it.

When Arthur failed to return from his quest, Leon was put in charge of a patrol tasked with finding him. After a day of searching they caught sight of Cenred's army (commanded by Morgause) marching for Camelot, and were swiftly run down by soldiers. Leon alone survived the attack, fleeing when he discovered that the soldiers couldn't be killed; Morgause had used the Cup to make the army immortal. He quickly made his way back to Camelot, where he related what he'd seen. Uther, however, ignored his warnings about the soldiers being immortal, and ordered him to prepare whatever defenses he could. The army reached Camelot that evening and attacked the following day. Both the city and citadel fell to the immortal army, after which Leon and the other Knights of Camelot were imprisoned in the castle dungeons and Morgana revealed herself to be a traitor, declaring herself Queen. One week later, Leon was brought before Morgana and asked to swear fealty to her. He responded that his loyalty was to Uther and Prince Arthur, and that he would rather die than serve her. He and the other knights were then assembled in the Main Square before a firing squad, where they were asked once more to pledge their allegiance. The knights remained defiant, and Leon watched, horrified, as Morgana responded by having her soldiers shift their aim to the crowd, killing many innocent bystanders. Later, after being returned to the dungeons, Leon was visited by Morgana's maidservant Guinevere, who had been sent to talk him into declaring his loyalty. Instead, the two conspired to escape Camelot and find Arthur, as Leon believed that he knew where the prince might be hiding.

They conducted their escape that night. Gwen stole the keys to the cells from Morgause's chambers and smuggled them to Leon, and the two then fled Camelot disguised as women courtiers. Once safe in the woods, Leon shared his belief that Arthur was likely hiding in a cave in the Darkling Woods, which he knew to have a concealed entrance and access to water. His hunch proved to be correct, and they were reunited with Arthur and his allies later that day. Their joy was short-lived, however, as unbeknownst to Gwen and Leon, Morgause and Morgana had known of their plans to escape and allowed it in order to track them to Arthur's hiding place. With a patrol of immortal soldiers closing in, the group was forced to go on the run. They were ultimately saved by the arrival of Percival and Lancelot, who dropped boulders from above to block the narrow path and halt the soldiers' pursuit. With their former hideout compromised, Gwen and Leon accompanied the rest of the group to the [//merlin.fandom.com/wiki/Castle_of_the_Ancient_Kings Castle of Ancient Kings]. There Arthur revealed his intentions to infiltrate the citadel and free his father. Leon was among those who volunteered to accompany him, and witnessed as commoners Gwaine, Elyan, Percival, and Lancelot were made Knights of Camelot by Arthur. The prince and his new knights then devised a plan to break Uther out of Camelot's dungeons: Merlin and Lancelot were to split off and disable the warning bell (though they were really planning to go after the Cup of Life) while Arthur, Leon, and the other knights proceeded on to the cells. Gwen and Gaius, meanwhile, were to remain in the Castle and prepare for any wounded.

The plan was carried out the next day. Arthur and the knights carefully infiltrated the dungeons, successfully trapping some of the soldiers in a cell and managing to hold their own against those that remained. Arthur had just managed to free his father when the warning bell went off, alerting everyone in the citadel to their presence. With their escape route cut off, Arthur resolutely led the knights in battle against the immortal army. They managed to hold their position for several minutes, long enough for Merlin to empty the blood from the Cup of Life, which instantly destroyed the immortal soldiers. Later, Leon accompanied the other Knights back to the Castle of Ancient Kings to escort Gwen home to Camelot (The Coming of Arthur).

The Darkest Hour
One year later, Leon was part of a group of four knights who came across a woman traveling through the Plains of Denaria. The woman was cooperative at first, explaining that she was journeying to the Seas of Meredor, but her demeanor markedly changed when Leon asked about the contents of her cart. Revealing herself to be the Lady Morgana, she attacked the knights with her magic. Only Leon and Elyan survived.

Later, Leon was among the knights who rode out with Arthur to investigate reports of strange, faceless beings who had attacked one of Camelot's villages. They discovered that the attacks were the work of the Dorocha, ghostly voices of the dead unleashed when Morgana tore the veil between the worlds on Samhain's Eve. Upon discovering that the only way to heal the veil was to travel to the Isle of the Blessed, Arthur set out on a quest accompanied by Merlin, Leon, and the other Knights of the Round Table.

They made camp the first night at an old fortress called Daobeth, where Merlin was badly injured by the Dorocha. When Arthur contemplated returning to Camelot in light of Merlin's worsening condition, Leon strongly urged him to continue with the quest, pointing out that hundreds more would die in the time it would take them to return and start their journey over. The dilemma was solved when Lancelot volunteered to take Merlin back to Camelot on his own, while Arthur, Leon, and the rest of the knights continued on with the quest. Leon did what he could to comfort Arthur about this decision, assuring him that he'd made the right choice and that if anyone could get Merlin back to Camelot in time, Lancelot could.

On Arthur's recommendation they took a shortcut through the Tunnels of Andor, which went fairly well up until they came across a group of Wildeorren. The knights quickly hid behind a shelf of rock, but despite their having used Gaia berries to mask their scents, one of the creatures followed them took a marked interest in Gwaine. This prompted the knight to kill the creature, which ultimately proved to be a mistake, as Wildeorren hunted in packs. The knights were forced to exit the tunnels at a run.

After another day of traveling, the knights were reunited with Merlin and Lancelot while making camp in another old fortress. Relieved that they were safe and well, the knights joyfully welcomed the two back into the fold. They reached the Isle of the Blessed the next day, crossing the lake by way of the ferryman's boat. When they discovered that the Isle was guarded by Wyverns, Leon, Elyan, and Percival remained behind to fend them off while Arthur, Merlin, Lancelot, and Gwaine proceeded on to the stone alter, where Lancelot ultimately sacrificed himself to heal the veil in Arthur's place.

Later, back in Camelot, Leon attended Lancelot's memorial alongside his fellow knights and the rest of the court. He was also present when a funeral pyre containing Lancelot's cloak and sword was burned in the courtyard (The Darkest Hour).

Further Adventures
Leon attended Arthur's birthday celebration alongside the rest of the court. Later, after the death of King Uther, he also attended Arthur's coronation along with his fellow Knights (The Wicked Day).

When it was discovered that Julius Borden was searching for the last dragon egg in existence, Leon was among the knights that Arthur took to find and destroy it. During their journey, Leon joined the others in playing a trick on Merlin. They pretended to eat all of the stew he'd fixed for dinner, and then proceeded to reveal one last bowl they'd saved for him just when he'd given up hope of eating. As a result, Leon and the other Knights were stricken ill when Borden poisoned their food, and had to be saved by Merlin's magic (Aithusa).

Leon was also present during the knights' ambush on King Caerleon's raiding party. When Caerleon's queen, Annis, subsequently declared war on Camelot over the death of her husband, Leon accompanied his fellow knights and the rest of Camelot's army to the battle sight. He later joined the other Knights of the Round Table in trying to cheer up Arthur by voicing their support and willingness to die for him. When Arthur struck a bargain with Annis that the war would be decided by a duel between two champions rather than a battle between two armies, Leon was among those who volunteered to represent Camelot. He later watched Arthur fight from the ridge alongside Merlin, the Knights, and the rest of Camelot's army (His Father's Son).

Leon was one of the knights who accompanied Arthur on his secret negotiations. While returning to Camelot through the Valley of the Fallen Kings, the group was ambushed by Morgana's mercenaries, and Leon, Percival, and Gwaine were separated from Arthur and Merlin in the battle. After returning to Camelot to recruit Elyan to help search, they eventually ran into Arthur the next day. Merlin, however - who had been injured during the battle - had been captured by bandits. Leon was part of the search party that scoured the woods in search of him, but the warlock remained missing until the following day. A day or two later, Leon was on a patrol with the other Knights of the Round Table when they encountered Merlin disguised as Dragoon the Great. The warlock was attempting to mount his horse so he could ride to Morgana's hovel and free himself of her Fomorroh's control, but due to the effects of his ageing spell did not have the strength to manage it. Recognizing him as the sorcerer supposedly responsible for Uther's death, the knights attempted to apprehend him but were quickly defeated by Merlin's magic, much to his glee. The warlock then mounted his horse using the fallen knights as a staircase and went on his way (A Servant of Two Masters).

When it appeared that Gaius had turned traitor and subsequently fled Camelot, Leon was the one to inform Arthur and Lord Agravaine that a horse had been taken from the stables. The two immediately assumed that Gaius had taken it, presumably as part of his escape (The Secret Sharer).

Lamia
When the village of Longstead was stricken with severe illness, Leon and the other Knights of the Round Table were tasked with escorting Gwen and Merlin there to provide treatment. Though Merlin did what he could, his prescriptions proved ineffective and it started to appear as though sorcery might be involved. The group started back to Camelot the next morning, intending to inform Arthur of their suspicions and return later with Gaius, who had remained in Camelot to treat a sudden outbreak of sweating sickness.

At some point in their journey they came across a group of bandits camped out in the forest. The Knights attacked the bandits, and in the process freed a young girl that they'd apparently taken prisoner. Identifying herself as Lamia, the girl appeared both terrified and distrustful, particularly of Merlin. She soon began to exert a strange control over the Knights; they became increasingly possessive of her and aggressive towards each other, Merlin, and Gwen. This eventually culminated in a fight between Leon and Gwaine (during which Leon sustained an injury to his arm) and they had to be forcibly separated by Percival and Elyan. The Knights also began to forget the original purpose of their journey (to save Longstead), concerned only with doing what Lamia suggested they do.

The morning after the fight, the group awoke to find that Elyan (who was supposed to be on guard) was missing. They soon found him unconscious in the woods, apparently suffering from the same sickness as the people of Longstead. Though Merlin and Gwen tried to convince the Knights to take Elyan back to Camelot for treatment, Leon (under Lamia's control) decided that they would take shelter in a deserted castle instead. Lamia disappeared almost immediately after they arrived there, and one by one the Knights began to fall ill; Gwaine when he went to collect fire wood, and Leon and Percival while they were searching for Lamia.

Gwen and Merlin were left to deal with Lamia by themselves. Merlin managed to stab her with a sword during their initial confrontation, but Lamia responded by transforming into a snake-like monster and chasing him through the castle. Eventually they ran into Gwen, who also attacked the monster with a sword after it managed to grab Merlin. The Lamia was unfazed, however, and likely would have killed them both had Arthur not arrived and finished it off. Leon and the other Knights were then taken back to Longstead, where Gaius treated them for their illness (Lamia).

Later Adventures
Leon participated in the jousting tournament that Arthur held as an engagement present for Guinevere. He was later present in the dining hall when Lancelot recounted the story of how he survived the veil, and joined the other Knights in welcoming him back. He later attended Gwen's trial when she charged with adultery for kissing Lancelot on the eve of her wedding to Arthur (Lancelot du Lac).

Leon was with Arthur, Merlin, and the other Knights when they came across the remains of a Druid camp. He joined the other Knights in teasing Elyan, who was complaining about Gwaine drinking all of his water. The next day he attended training with Arthur and the Knights, and was present in the armoury when Elyan and Gwaine got in a small fight, during which Elyan was knocked unconscious. When they told Gaius what had happened, Leon and Gwaine asked that Arthur not be informed of what had happened, explaining that Elyan hadn't been himself lately and they didn't want Arthur to think that his loyalties were divided. Later, after Elyan attempted to kill Arthur, Leon searched the castle for him along with Gwaine and Percival, eventually apprehending him in a castle corridor (A Herald of the New Age).

Leon was present when Arthur announced Camelot's new agreement with the kingdom of Nemeth and his imminent marriage to Princess Mithian, as well as at the Princess's arrival. Some time afterward he discovered the body of a young man who appeared to have fallen from one of the castle parapets, and reported it to Lord Agravaine. Later, he participated in a hunting trip that Arthur organized for Mithian and was the first to spot a deer, not knowing that the deer in question was really Gwen, who had been enchanted (The Hunter's Heart).

Morgana's Second Conquest of Camelot
When a fire affected the citizens of Camelot, Leon and Elyan go to aid. Then the Southron Army attacks and Leon is involved in a minor battle. The Southron Army wins the battle and Morgana is once again crowned Queen of Camelot. He flees the kingdom when it is under Morgana's second reign. He later joins Arthur in reclaiming Camelot once more. It is certain that he survives the battle because he is seen at Arthur and Gwen's wedding (The Sword in the Stone).

Searching for the missing knights
Leon later accompanies Arthur to search for the knights. He enjoys the feast in Queen Annis' palace, and then accompanies Arthur towards Ismere, fighting bravely when they are ambushed by Morgana and Ruadan's men. He fights Ruadan himself, but is defeated. He and Elyan later return back to Camelot not knowing what happened to Arthur and Merlin. (Arthur's Bane)

Poetry
In The Death Song of Uther Pendragon, Leon hears something in the cellar of the palace. When he walks in to investigate he finds Arthur and Merlin standing there, staring at him. Merlin then explains that he was teaching Arthur poetry, and that Arthur couldn't get enough of it. Arthur hesitates, then agreed, saying that he indeed loved poetry. After a moment of shock, Leon nodded, smiling, telling Arthur to enjoy his poetry (The Death Song of Uther Pendragon).

The Dark Tower
Leon is bitten by one of Morgana's enchanted snakes and while on their quest to rescue Gwen from imprisonment by Morgana, Percival and Leon wake to the same nightmare- they describe The Dark Tower, a place that knights dread. Arthur is familiar with the tower, describing it as a place that can bring doom to those who even hear of it. Gwaine lightens the moment by describing his dream about eating a cheese that tasted like apple pie, and goes back to sleep as the others gaze at him awkwardly, he and all the other knights were present at Elyan's funeral (The Dark Tower).

Personality
Leon is very loyal to the Pendragon family. Because of this loyalty, he refused to fight to his full ability and strength when jousting against Arthur, out of fear that he would injure the prince. He also tried to stop Merlin from interfering with a meeting between Arthur and Uther. However, Merlin convinced him to let him in by telling Leon that Arthur was trying to kill his father. Leon refused to pledge himself to Morgana, believing that she had no right to be queen because Uther had never given her that right by declaring her to be a Pendragon and because she had taken over Camelot with dark magic and violence, with no regard for the citizens of Camelot. Even when Morgana had Leon and his men at the mercy of archers armed with crossbows, declaring that they would be spared if they pledged to serve her, he and his men defiantly refused.

Leon is very courageous, even when faced with overwhelming odds or magical opponents. He even helped defend Camelot from the Great Dragon. He also fought against Cenred’s warriors and the undead skeleton army during the siege of Camelot. However, Leon knows the difference between bravery and foolishness. Therefore, he fled from Morgause’s immortal army when he realized that they couldn't die, thinking that he should warn Camelot instead of staying to face what would have been certain death. He was also a skilled leader and, during Arthur and Merlin’s search for Balinor, he took command of the knights of Camelot. When Morgana declared herself Queen, he was also shocked and horrified as she ordered her soldiers to attack innocent people, demonstrating his concern for the well being of the citizens of Camelot.

Leon also had a sense of humor. He and the other knights sometimes teased Merlin and it is apparent that Leon thinks of Merlin as a friend. Leon also interpreted Merlin’s desire to kill Arthur as a joke, not realising that Merlin, while under the influence of a Fomorroh, actually meant what he said.

Arthur Pendragon
"I have fought alongside you many times. There is no one that I would rather die for."

- Leon to Arthur

Leon respected the king and looked on him as a friend. Together they fought in many battles and went on many adventures. He also had high respect for Arthur as the prince, once refusing to beat him in a jousting tournament (The Once and Future Queen). Their relationship grew when Morgana was queen and they went into hiding. Arthur made Leon a Knight of the Round Table, an honor bestowed on only his closest and most trusted knights. The next day, Leon helped Arthur, Merlin, and the other rebels defeat Morgana. Leon stated that there was no one else he would rather die for and that he would follow Arthur to the mouth of hell if necessary (The Coming of Arthur, The Sword in the Stone). He has also been a pillar of faith and a source of comfort for Arthur, when he assured Arthur that Lancelot could get Merlin back to Camelot safely while they continued on their quest to The Isle of the Blessed (The Darkest Hour). Leon also was very devastated when he had state that Arthur had died.

Guinevere Pendragon
Leon knew Guinevere very well because Gwen’s mother worked in his household when they were both young. When Morgana was queen and Gwen helped him escape, they were very comfortable when talking to each other (The Coming of Arthur). Leon was delighted when he found out that she and Arthur were getting married. He showed his tribute by giving her a ring shortly before the melee (Lancelot Du Lac). After Morgana had been overthrown by Arthur and he had regained the Throne, Leon was one of the witnesses to Arthur crowning his new wife, Guinevere, as Queen of Camelot. Leon was at Gwen's side when she was made Arthur's successor after his death at Mordred's hand during the Battle of Camlann.

Merlin
At first Leon didn't really know Merlin, but once he became a Knight of the Round Table they became great friends (The Coming of Arthur). He enjoyed tormenting Merlin in jest and showed that he cared about him when he was upset at finding out that Merlin was nearing death on their journey to the Isle of the Blessed (The Darkest Hour). Leon also had a tendency to playfully tussle Merlin hair and appeared to trust Merlin greatly, as he allowed Merlin to take a crossbow for Arthur and even thought that Merlin was joking when he, under the influence of a Fomorroh, said that he wanted to kill Arthur (A Servant of Two Masters).

Uther Pendragon
"My loyalty is to the King and Prince Arthur. There is nothing you can do to change that."

- Leon to Morgana Leon respected the king and was just as loyal to him, albeit not as close, as he was to Arthur. However, he was willing to disobey Uther's orders and, despite Uther's command to keep everyone out of the king’s chambers while Arthur fought him, he still let Merlin in once he was told that father and son were going to kill each other (The Sins of the Father). Leon was apparently one of Uther's favorite knights because the king made him one of the leaders of the battle between Camelot and Cenred's army (The Tears of Uther Pendragon).

Morgana Pendragon
It can be assumed that Leon greatly respected the Lady Morgana as much as all the residents of Camelot did. However, this changed after her betrayal was exposed. Witnessing her cruel methods, he denied to bow down to her and serve her once she was queen and swore loyalty only to Uther and Arthur. Even when she was about to execute him, along with several of his fellow knights, he still shouted "Long live the king", much to her disappointment and anger. When she, instead of executing the knights, had several of Camelot's citizen shot with crossbows, Leon was shocked and extremely upset. He also took a leading role in taking Camelot back (The Coming of Arthur). A year later, he found her carrying a cart on her way to the Sea of Meredor. He halted her, oblivious about who she was. She immediately attacked him but did not kill him. He later reported her powers had greatly grown (The Darkest Hour). When she conquered Camelot for the second time, he was one of the knights to lead the attack against the Southrons (The Sword in the Stone).

Gwaine
Leon first met Gwaine when he placed him under arrest under the orders of the king for "attacking" Sir Oswald (Gwaine). However, when Gwaine was made a Knight of Camelot, Leon started to respect him and eventually became friends with him (The Coming of Arthur). Both being Knights of the Round Table, Gwaine is one of Leon's fellow knights and close friends. Sir Leon enjoys pulling pranks with Gwaine and takes his jokes in good humor. Gwaine seems to have brought out the more mischievous side of Sir Leon. The two fight well alongside each other and never argue. The only time they fought with one another was when they were enchanted by the Lamia, which resulted in Leon getting a small wound in the arm (Lamia).

Lancelot
"If anyone can get Merlin back to Camelot, Lancelot can."

- Leon to Arthur Leon first met Lancelot when Lancelot and Percival saved him from Morgana’s immortal knights. Not long after, Leon watched him become a Knight of Camelot when they were all made Knights of the Round Table. Then, they went on to overthrow Morgana and Morgause (The Coming of Arthur). They had many adventures when they were both knights. Leon was very upset when Lancelot died on the Isle of the Blessed (The Darkest Hour). When Lancelot returned, Sir Leon, along with the other Knights, was absolutely thrilled at the apparent return of a dear friend. However, when Lancelot had the affair with Guinevere shortly before her wedding to Arthur and then took his own life in his cell in the dungeon (under Morgana's orders), Leon was again very upset with the second loss of his friend (Lancelot Du Lac).

Elyan
Elyan and Leon knew each other very well since Elyan’s mother worked in Leon’s house when they were boys. Together, they had many adventures once they were knights and they were great friends. Despite this, Leon still deliberately annoyed Elyan once in jest by not giving him any water (A Herald of the New Age).

Percival
As they were both Knights of Camelot and Knights of the Round Table, Leon and Percival went on many adventures together, as well as joking around with each other. They were both amazing fighters and extremely loyal. They were also the only two to survive out of the original six.

Abilities
As one of the longest-serving Knights of the Round Table, Sir Leon is an excellent  swordsman, surviving many battles in which many other knights were slain. He is capable of fending off immortal opponents such as Skeletons and Morgause's immortal army and dueled against the powerful warrior Ruadan, although he was defeated in this duel. Leon is also skilled with a lance and once, while practicing against Arthur, he would have defeated the prince if not for the fact that he was worried about injuring him. However, it should be noted that Arthur had the sun in his eyes during the practice session.

Leon also displayed remarkable luck, being able to recover from the wounds inflicted on him by the Great Dragon, survive a battle with Cenred’s men long enough to be revived by druids who had him drink from the Cup of Life, and escape from a group of immortal soldiers unscathed. On the first occasion, Arthur and Merlin were the only others who are known to have survived besides Sir Leon. On the last two occasions, Leon is the only person to survive. He also, along with Elyan, survived an encounter with Morgana, in which two of the four knights involved were killed.

In the Legends
While Leon appears to be a completely original character, it is possible he may also be based on or around King Leondegrance. King Leondegrance, or King Leon, was the father of Queen Guinevere and his kingdom was Carmelide or Cameliard. He served Uther Pendragon, King Arthur’s biological father and regnal predecessor. Leondegrance was entrusted with the keeping of the Round Table at Uther’s death. When Guinevere marries Arthur, Leondegrance gives the young king the table as a wedding present. In later romances, Leondegrance is one of the few kings who accept Arthur as his overlord. For this, his land was invaded by the rebel King Rience, but Arthur came to his rescue and expelled the enemy. Arthur meets Guinevere for the first time during this excursion and they develop a love that eventually results in their fateful marriage.

It is also possible Sir Leon's characted is ispiredd by Sir Lionel, how, according to the legend, was brother of Sir Bors de Gannis and cousin of Sir Lancelot and Sir Hector de Maris. When Lancelot was exiled due to his romance with Guinevere, Lionel goes with him, and in killed by Gawain in the battle of the Joyous Garde, in Wales, where Arthur's armies fought against Lancelot troops.
