Yalkara, also known derogatorily as the Mistress of Deceits and the Demon Queen, was a member of the Hundred Charon, who escaped the void and took control of Aachan. She was the youngest of the Charon and considered to be the second most powerful Charon mancer, after Rulke. It was Yalkara who gave the Charon the opportunity to flee the void, by using Chthonic fire; the soul-core of the Stilkeen. This folly caused the trouble of all the Three Worlds, though in her final moments Yalkara willingly sacrificed her life to make amends for the damage she had caused.
