Ephemural is a demigod and one of the antagonists in Twokinds. Like all the other demigods, she is the caretaker of a specific race, hers being the Keidran. She is apparently the cause of Flora's pregnancy, claiming after her return to the Demigod realm that there is a race that she has not allowed to exist for many years, and that "I have no choice. I must ensure at least some Keidran blood survives." Ephemural is the cause of Trace's amnesia.
