Long ago, longer still than even the golden age of Hamset, so long it is out of the memory of man, though not of the elves for they remember their history to the first. Many secrets areheld by the elves. As this, a glass vial containing the tears of Laitha, the fairest, kindest and most beautiful living being to grace the world of Hamset.
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.
