Dragon Egg

A Dragon egg was an egg from which Dragons hatched, having been called into the world by a Dragonlord. Following the Great Purge, all but one was destroyed.

Merlin and King Arthur Pendragon set out with the Knights of Camelot, with the latter two wishing to destroy it and the former to rescue it and return it to Kilgharrah - the last surviving Dragon. Merlin was successful in his goal and the Dragon was born. Merlin named it Aithusa (which means 'light of the sun") and Kilgharrah noted that, as a white Dragon, it was a sign of good times to come for Camelot. (Aithusa)
