The party has chosen to work their way up from level 7 of Castle Whiterock, looking for traces of the previous player group, who were TPK'd in the dungeon. The previous group, however, did such a great job of depopulating the dungeon levels above them that I now have to fill in the blanks.
Need to buff up the slaver party; the PC have wiped out the small derro camp at the foot of the elevator. Thane Vejik is tired of all these nuisances; the flow of slaves must never cease! More surprises await above...
The party finally wiped out the last of the toad god cult and the undead troglodytes, but random encounters in this area will keep them from getting lazy.
This area was wiped out by the previous party but is now quiet, filled only with scavengers and a few escapees from the original purge. The bugbear lost a bet and has to scavenge for food for the others above.
More nuisance monsters. Where do these stirges keep coming from??? The White Roc orcs have fully retreated to the inside of the fallen tower, insufficient in numbers to secure the entire level and insufficient in power to negotiate with the stone giants up above.
This level is mostly empty except for the duergar envoy party, who are engaging the giants in negotiations.
At this point the party simply has to gain access to the surface. Since they are already on fairly friendly (ish) terms with the stone giants, that shouldn't be too hard unless they antagonize the sentry.
And perhaps more important; what are they doing?
