Who is she again?
When Diablo was running amok during that time the church was fighting Tempest, there were 3 battle sages. 1 of them got stuck fighting (more like being toyed) by Ranga, the other 2 were attacking Diablo.
That Glenda woman shot Diablo, saw that it was pathetically ineffective, yeet herself out of dodge so fast the remaining sage didn't even realize he was abandoned.
I love them so much
