For the episode with the same name see: Aithusa (episode).
Aithusa is brought into existence when the dragonlord, Merlin, rescues her egg from the Tomb of Ashkanar and Julius Borden. A dragon will only hatch when a dragonlord gives it a name. Using his power, Merlin names the hatchling Aithusa.Kilgharrah, The Great Dragon, notes that the name Merlin chose is very fitting, for in the Dragon Tongue, her name means "Light of the Sun". It is fitting because Aithusa is a rare white dragon, and her birth symbolises a good omen for Merlin's destiny, for Arthur, and the land that they will build together.
"Aithūsa" is Greek (Αἰθουσα) for "she who burns (transitive)", i.e. "she who burns things".
Aithusa presumably remains with Kilgharrah while maturing. When Morgana loses the throne of Camelot for the second time and is gravely injured fighting her way out, Aithusa flies to where she lies in the forest and heals her wounds. Morgana appears both shocked and elated at the sight of the dragon, smiling in disbelief as Aithusa flies away once again right after healing her (The Sword in the Stone).
Tormented Ally of Morgana
Aithusa bonds with Morgana within the next three years since they spend two of those years imprisoned and tortured together. By the time she visits Morgana just before Arthur and Merlin arrive to rescue the Knights Morgana captured, she has grown quite a bit larger, although still small enough to fit in Morgana's bedroom and in the caves Morgana is searching. Aithusa attacks Merlin, Arthur and Gwaine, who are all shocked that Morgana has found a Dragon. Merlin chases after her and when she tries to attack him he blocks her fire with a magical shield and then uses his Dragonlord ability to stop her from attacking again. Merlin realises that something traumatic happened to Aithusa, and it is revealed that she can't speak. Merlin lets Aithusa go not realising that Aithusa is loyal to Morgana. Aithusa displays her loyalty to Morgana by presumably healing her after she is wounded by Mordred and is last seen following Morgana through a blizzard. (Arthur's Bane:Part Two)
Aithusa is a female dragon, or (dragoness) with white scales, and wings with a white, almost transparent membrane. She has big, light blue eyes, four horns, short neck spikes and tail spikes. Since she is female, her body structure may turn out to be more feminine than Kilgharrah's, but for now it is unpronounced until she grows older.
As a newborn, she was about the size of a small bird. After three years, she appears to be the same size as a Wyvern. How long it would take for her to reach Kilgharrah's size is unknown.
Aithusa has a very mysterious personality. She saved Morgana's life, although it is unknown exactly why. This might have been out of compassion, or she might have had a darker motive. Either way, Aithusa has been shown to have a genuine bond with Morgana, who treated her like a pet. Aithusa appears to be mute since she has never been seen speaking, although this might be because she simply hasn't learned to speak since she is only three years old.
Aithusa was, like Morgana, traumatised from being imprisoned and tortured for two years. It might have been this trauma that made her unable to speak.
As the last Dragonlord, Merlin used his powers to summon Aithusa from her egg and gave her a name. However Aithusa later saved and bonded with Merlin's arch enemy Morgana. Aithusa attacked Merlin, Arthur and Gwaine and Merlin chased after her and used his Dragonlord powers to stop her from striking again. He could tell that something terrible had happened to Aithusa and realised that she couldn't speak. When Merlin told Aithusa to go the first time, she didn't want to. But then he commanded her to leave. Although Arthur had mentioned that Morgana now had a Dragon, Merlin appears to be unaware of Aithusa's loyalty to her since he allowed the white Dragon to leave.
Kilgharrah was Aithusa's Dragon guardian. He initially thought that Aithusa was male. Aithusa later saved Morgana's life and appears to have betrayed Kilgharrah. It has been said that Kilgharrah will not be the same Dragon he used to be because of his ward`s betrayal.
For reasons that have not been revealed, Aithusa saved Morgana at the brink of death. Morgana was grateful and elated when she did this. Under unknown circumstances, the two were imprisoned and tortured for two years and after escaping, both of them were still haunted by their past experiences. Morgana was protective of Aithusa and reassured her that everything will be alright. Morgana treated Aithusa like a pet and the white Dragon seemed to be the only thing she genuinely cared about. Aithusa was shown to be loyal to Morgana and attacked Merlin, Arthur and Gwaine, although she couldn't resist Merlin's Dragonlord powers. She was later seen following Morgana through a freezing blizzard outside of Ismere.
Aithusa is a dragon of the same type as Kilgharrah, so she has many or all of his abilities.
- She has great magical power that is used through her breath. She can use it to heal, gift knowledge or power, and breathe fire.
- She was able to fly only a few weeks after her hatching, even though her wings weren't fully grown.
- When she is bigger, she will have immense physical strength. She can use her wings, spiked tail, talons, and teeth to great advantage in a fight. For now though, she is only the size of a wyvern. She also breathes fire.
LegendsIn the legends, the red dragon kills the white dragon (symbolising Aithusa). The red dragon is most likely symbolising Kilgharrah.
- When the writers learnt about the fans debating whether Aithusa healing Morgana had to do with the white and red dragon legend or not, the only thing they said was that "we hoped it was a nice tease...".
- Katie McGrath has stated in an interview that Aithusa is female, despite being mentioned as "he" in series four.
- It has been confirmed that Aithusa will be Morgana's confidant in Series 5 in the same way that Kilgharrah is Merlin's confidant.
