Llerwen

Llerwen was a True Ancestor who possessed the ability to distort life and create new beings.

History
He was not well liked by the other True Ancestors. They did not actively torment him, but he did not have any friends due to his general lone ranger philosophy. Thus, when he retreated into his laboratories in The Dragon's Fangs, no one really thought it odd. When he began his experiments on the Life Stream, a Supreme Subjugator came to take him down. Llerwen, however, had been studying the powers and weaknesses of the Supreme Subjugators, and laid a trap that was very successful.

With the captured Supreme Subjugator, he began a series of experiments that ended with the creation of his magnum opus, the Prime Revenant. He meant to use it to control the other Immortals and Dark Creatures. It immediately backfired and ate him. Because of the True Ancestor's direct connection to the Lifestream, he inadvertently increased its power to unsafe levels, becoming a direct threat to the Lifestream. It was thwarted by Llerwen placing limiters on its powers, forcing it to seek out ways to remove them. Llerwen also had placed more harmless creations in safe places, that would, in the event of his destruction, seek out powerful Immortals. Tanith, an Administrator, was eventually contacted by one of them, and he gathered the other Administrators and Moderators in battle to fight it.
