Birth of a Necromancer

A human is found on their knees in a field surrounded by bandits and the corpses of fallen allies. Chanting the Prayer of Grenth, they cause their fallen allies to rise and defend them.

"Where is the god to whom I may give my undying devotion? Where is the god to whom I may beg revenge against those who scorn me?"

Note that Necromancy on its own is not considered evil, indeed it is approved by Grenth, though using allies for it is considered taboo.
