I'm guessing that through the patch cycles we'll discover her blindness and will have to kill some sort of dark being, possibly (probably) named Astos who has developed or is guarding a crystal eye from which she can regain her eyesight. Or at least something similar to such a endeavor.

Is no one else drawing parallels from a wide-brimmed-hat wearing witch, living in a cave with sweeping brooms that partially talk backwards, conveniently named Matoya and a case of curing blindness?
