Necromancer on Elder Soteria Brainstorming

Working on writing up the Necromancer of Elder Soteria plot. I’ve got the main antagonist completed and I know that some characters are already wanting to play (@Dasfier and @TheChubbyGamer in particular).

So far what we’ve got is the Necromancer has returned from the time just before the banishing (see these notes on the Banishing part of the Peace of Ages). IIRC @Buckethead also wanted to participate. Remona (Dasfier’s character) and Lisa found some runes and old books that had pointed them in a direction but we haven’t moved forward on that yet.

I’d like any suggestions on plot points or what we want to do with this plot.
