We've been having a blast with the NPCs, a pretty cohesive group lead by the PCs. The external threats have been stronger than the internal tensions. Having built up those ties, I'm now starting to turn on the gas.
Topsy and Turvy flipped out during a boat crossing in rapids in the Darklake. The party had no magic or silver weapons and were eventually forced to throw them overboard.
In Gracklstugh the party acquired poisons. These were stolen and covertly fed to Ront. He survived only because someone had Lesser Restoration. The party suspects Sarith, who has been acting increasingly erratically. They have seen flashes of red behind his eyes*, they think Sarith might well be possessed, killing people in his "sleep". They are close, but it is Buppido that is starting to get lively, he'll try an assassination every day he is in Gracklstugh, trying to frame someone else. He'll take souvenirs to his shrine.
*from the portrait, though I don't really get that. I've also told the party that Sarith has a bad rash, also based on the portrait.
I need some help with Sarith's infection, how does it work, how does it (physically) manifest?
I'm going to have Sarith act increasingly erratic, manic-depressive, berserker fury, that kind of thing.
