Well the party, upon hearing the kill order charged galantly into combat, except the rogue, who commenced to shooting anyone who shot at Demetri. Demetri got wounded bad enough to decide to cast invisibility and use a ring of flying to make good his escape, so he'll be back later.
Meanwhile the party hauls Samara up in front of a midlevel cleric and get's her geased to insure she doesn't attack the party again.
Party meanwhile finishes the tomb raid and learns the general location of 3 magic items they need to recover - a sword, a shield and a suit of armor. Elven lands have the sword, dwarves have the armor and the shield is on the plane of Ravnica (plane hopping is so much fun

)
Meanwhile I'm going to reintroduce Demetri in a hellaciously more EVIL way. I was paging through the Monster Manual for random encounters - Dire Bear, Displacer Beast...
DOPPLEGANGER...
Hmm methinks.. Huge hmmm.. If the player really wants his old character back (and at this point I'm inclined to think he does) I can slip in the doppleganger as a spy of Triel's absolutely loyal to Triel -- Hell I can say the doppleganger was the one they fought already -- which opens the question, where is Demetri?
Anyway, still looking for evil Rat Bastardly ideas.
Here's something I created for the party at session start - a collage of group portraits to use as a desktop background (I use a projection screen to display the dungeon, so this gives them something to look at between scenery programs).
