ToME: the Tales of Maj'Eyal

Which I just did in fearscape. Does that mean you don't go to zigur together? What if I go to zigur now?

Every other time, and there have been dozens of times, he speaks while I'm attacking him and offers to go with me. But this time I just killed him.

What now?

You have to have at least ten spells (Is Spell = True talents, so far as I know) for the grand corruptor to talk to you, otherwise you just kill 'im. Once that happens, well, you take your loot and move on.

Also just killing him proves you're a better person!
