Thaos

Thaos ix Arkannon was a member of the Engwithan civilization and grandmaster of the Leaden Key, an organization devoted to keeping the secrets of the gods. Having allied with the goddess Woedica, Thaos possessed the power to recall the memories of all his past lives, making him one of history's most notorious schemers. He was killed by the Watcher of Caed Nua, bringing an end to the Dyrwood's Hollowborn Crisis.
