"De Kanaar folk tink all dere gods and medicines are secret. But I live in dese marshes long enough to hear dere gods, whether pointy-ear folk like it or not. I can hear dere comin's and goin's, an' I can make dem see you or skip you as you like."
- Tonis, hillaq of Rakart Village
"Anyone can draw a map, boy - there's no more difficulty in that than laying brick. What makes maps useful is when they are so proper, so precise, that they are living images of the places they represent. Encompassing knowledge of the geography, and mastery of the very space itself - that, child, is cartogramancy."
- Sage Pakpao Sasithorn, Chief Lecturer, the Ezagun-Darkbolt College of Cartogramancy
A vicious murder happens in a town that the party happens to pop in at. Under heavy suspicion as they are strangers, the party is forced to discover the perpetrator or have their reputations blackened, especially as more and more murders occur in the town, and mysteriously stop and restart when the party leaves to go kill off that evil necromancer who kidnapped the princess.
The only problem is that a demon, possessing one of the party, is the perpetrator. And the demon makes no signs that its living in the PC's head.
In fact, for all the party knows (except for the possessed person's), their companion is an evil murderer.
Do they try and execute their friend as he's a vicious murderer, and no evidence points to demonic posession? Or do they flee town with him, trusting him, and have their reputations destroyed?
