Definitely out. Unfortunate.
Anyway, you can indeed continue with the story with a new party. Have the current adventurers arrive just too late to stop the portal, or whatever it is, from opening. A great horde of demons springs forth and the heroes get trapped in their final glorious battle. Gorshak charges close to the portal and tries to use his enormous bulk to hold back any more monsters from coming through. Mardok and Shaster charge around the battlefield like rabid mother




ers butchering everything. Quinn starts some serious god power ritual he remembers from a long past existence, knowing its a ritual so powerful it'll be his last. For now, the git.
Anyway, with all the demons in the keep busted up, Mardok and Shaster's attentions return to the portal where Gorshak is getting slowly battered into oblivion and already pretty much dead, holding on by sheer will. Mardok charges to the rescue, leaps over Gorshak's head and through the portal into whatever hell dimension it is. What he does there... well, the demons stop right away. Gorshak collapses from his wounds and dies.
Quinn's aura explodes, he drops to his knees and utters a final prayer and then dies. The portal is shut.
Uh... Shaster does...
Anyway, a few days later, the next new group of "adventurers" are really just some brave townsfolk from Winterhaven who come to check thing out. They find the fallen heroes, along with loads of dead demons and a freshly sealed hell rift. Oh, and blood. So much of it.
Oh, er, maybe not. Hell, I hope thats not the actual modules real story. It's just an idea if the game times fall apart completely for all of us... either way, when you kill Gorshak off don't do it by making him fall down a flight of stairs. Unless he lands of some boss creature and squashes it flat.
