Ephemural

Ephemeral  , also known as Neutral , 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.

Additionally, she took control of Mary Silverlock for quite some time on the grounds that she'll give Mary her humanity back and that she'll be delivered to Flora.
