Those left standing: Dorita, Kazbo Spinfist, Andreas. Those who fell: Damon Arlo, Stitch.
We'll be diving to retrieve Damon's body. He was wearing the ring of conjuration anyway, so it's important to get him. Of course, if Jay and Pete want, we'll buy Raise Dead spells to have the rezed. We have plenty of gold so this isn't a problem.
With Erebus gone, our next move should probably be to have a funeral for the ruler of Waterdeep and his two court wizards. We can place ourselves in good standing with the rest of the royal court that way, and probably make some great contacts to boot. I think one of us should check in with King Gorlar and see how the battle with the drow went. Maybe there are some dwarf scouting parties wandering the tunnels mopping up pockets of drow that are left. Or, on the other hand, the dwarves could have lost and then we have a whole new problem to deal with.
We've also now recovered four of the eight rings that, when re-combined, will resurrect Mystra, the goddess of magic. Here's the catalog: Ring of Divination: Andreas; Ring of Conjuration: Damon Arlo (currently on his corpse in the ocean); Ring of Necromancy (party fund--this ring turns anyone who wears it into a vampire); Ring of Evocation: Keira.
Kudos to Stitch who pretty much single-handedly took out Erebus! What a dastardly rapier wound.
