Mithyn

So far we know very little about Mithyn, other than she appears to be some kind of divine being or goddess. During the interlude between chapters 2 and 3, she discusses Zelica's captivity with Mystery Divine Being as well as a mysterious tower that seems to be what broke King Alonon's spirit when he looked inside.

Given Vera's impression that the Goddess of Magic has wings, Mithyn is a candidate for the role. Another possibility is that she might be the "Mother of the Succubi" of elven mythology, assuming that each goddess created her race in her own image.
