You are just past the point where the narrow ledge below Ilvara's chambers (6-8) widens out. The demons are in the center of that large open area south of the lift.
For the party, I'm inclined to go back to Room 6-8, as I am not equipped to deal with a demon and will be extremely ineffective. Hunter will go along with what the party decides, though, given that there's relative safety in numbers.
I agree with CancerMan. It's a rock and a hard place. Priestesses or no, the threat of a demon would probably force us to retreat to the nearest shelter. In this case, Ilvara's tower. Dun-dun-duuuuun! :-D
It would be interesting if we could get Ilvara and the demon to take each other out as CancerMan suggested hehe!
As mentioned, all I know is we have a spider in the temple place, but I suspect its not a normal spider (I'm guessing we're talking about a large spider, right GM?)
So it's a choice between fighting our way through a vrock, two lycanthropes, and the drow guards to get to the lift, or fall back to the tower, fight drow priestesses and a giant spider, and hope that if we survive, by the time we come out the vrock will have taken out the lycanthropes and all the guards... :-D
I honestly don't know what a vrock is other than it's some sort of demon, so I'm not even capable of metagaming here! :-D But yeah, lemme stop thinking like a player...what would Mai'ngor, Tikbalang Champion do?
EDIT: Yeah, rolling up a new character now just in case! :-D
How big is Stool? As a sprout, I'm assuming small, but is he small enough to carry like a toddler?
EDIT addendum: And for the lift, when it requires an operator, does that mean someone has to control the lift from somewhere else, or can it be controlled from the lift itself?
