The Dragon Knights were an ancient order founded in the Keldarain Era. Each Knight was the result of a bonding between mortal and dragon. They shared a spiritual connection which bound the two together, and through this, a fragment of dragon essence was absorbed into the Keldarain undergoing the ritual. After the cataclysmic event that ended the Keldarain Era, the Knights died off, along with the rest of the Keldarain races, but part of their essence survived through the Nor'l, becoming directly intermingled with that of the new elves. This latent connection would much later be re-awakened by the magical forces of Umbra, leading to the rise of the dark elves.
