So the spooky elf in the mirror is the one who gave/taught mankind dark magic in the first place, the whole “Mankind came up with this evil!” Immediately and permanently thrown out the window when people find out. I get that.
But what’s he trying to do? He’s pretty much stuck in his magical prison and it’s been kind of a long while since he’s been in there.
Why not just kill him?
