Zydriss, The Undying

Zydriss The Undying. Is Great Wyrm, Obsidian Dragon whose age isn't known exactly. Zydriss lusts for dominion over M'Erenal. Likely due to the Psionic power and knowledge located there. Zydriss has been defeated 3 times in written history twice by Taldel and most recently in 1417 by Patir Nadaar and Deus Umbra. Zydriss is the progenator of the Dragonborn and creator of the plane of M'Erenal's Sister City, Citadel of Time.

Zydriss's name was used in nursery rhymes to convince children to do as they were told. If you didn't go to bed, Zydrss would come for you.
