"You do not need to be a cleric to bring light into the world."
(a Mage follower of Isis, npc suitable for any fantasy campaign with gods of light.)
Magic is a blessing and curse, life and death, birth and undoing, a goal and a way.
Once the daughter of a royal family of the Living Lands, Golden Tears Mistress forsook her family’s ancestor offerings in exchange for the privileges of the court of First and Night-Crowned Wolf.
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?
