I'm sure someone's probably already thought of this, but I just realized it while skimming through the preview of STAP listed in Dungeon 138.
It states that the PC's are able to bargain for the assistance of Orcus, Malcanthet, or other demon lords . . . .
Would this also include the Lord of Occipitus in the event that the PC's are able to contact them?
I would think that if there's a group of players that's going through STAP that's already gone through SCAP, running into an old character could be . . interesting.
