yeah, it was a little confirmed lol.
maybe I misread the event, but I thought he said out teacher was in Northcrest for a short time, might be my bad. ill check again.
he corrupted the lake and such because he can't reach inside the temple, something is protecting everyone (except us) from his power. also, it's because he needed the barrier to fall so, he could get the gem. so yeah, the magic of the lizard folk is pretty much exactly why he needs them corrupted lol.
mentioning it does make him kinda fishy, I wonder what's going on without us knowing?
