Dragon

For information on Dragons outside Merlin, see dragon.

History
Dragons had a special bond with the Dragonlords, the Dragonlords could talk to, tame and kill a dragon. According to the Old Religion, they are brothers to Dragons, connected through their souls so that Dragons obey Dragonlords.(The Last Dragonlord)

Dragons were old allies with Trolls. (Beauty and the Beast)

During the Great Purge, King Uther Pendragon had all Dragons killed except for Kilgharrah. He tricked the Dragonlord Balinor, he asked him to bring Kilgharrah to him so he could make peace with it. But instead, Uther imprisoned him beneath Camelot and then had all the Dragonlords rounded up and killed.(The Last Dragonlord)

Appearance
The Dragons in Merlin have many similarities to Dragons in myth. Dragons are massive scaly, four legged creautres, they have long tails and large wings. They have Golden Eyes.

Abilities
Dragons had great knowledge and power in Magic. They were impervious to almost any weapon, an enchanted spear hurled at a Dragon would just bounce off it's scales despite being filled with Magic (The Last Dragonlord). As with all Dragons in Myth, they had the ability to breathe fire. Despite his massive size Dragons are far more graceful and much faster than they appeared, able to easily avoid numerous projectiles such as arrows even when they were fired at the same time. Dragons could easily defeat defeat a whole group of Human knights (though not without an injury) and they seemed to be undefeatable to anyone except the Dragonlords. Dragons are an incredibilly powerful almost indestructible enemy in combat, a single Dragon being able to ravage a city within weeks.

In addition to being virtually unbeatable, Dragons had the power to transmit spells from their thoughts into another persons mind (The Curse of Cornelius Sigan) and they could use their fire to fill the Weaoibs with magic giving it great power (Excalibur). Due to Kilgharrah's prodigious knowledge of the future it's likely that Dragons could foresee the future, though he may have learned the future from another source.
