You need to make offerings at the altars of various Gods in a specific order. If yo complete it, it gives you some neat benefits. Click and read.
So, what if I've made the offering in another way.? Why do I die when I offer myself.? And why won't the altar in the Gorgoth Pass, accept my offering.?
I've never actually completed the God's Quest (I keep getting side-tracked into doing other stuff), but I am almost 100% certain you'll get killed unless you do the Quest totally according to schedule. As for the altar -- sorry; that's one of the ones I tend to forget about.
If you've made offerings in the wrong order, I believe that you can still do the gods quest, by just starting doing it the right way.
Yeah. You can just go back to the start of the current circle you are in i.e. good, neutral and evil.
