Not strong of body, and questionable of mind, she has a kind heart and one special talent. She is not a healer of wounds, or even of people, she heals the souls of creatures. She feels sympathy for even the most hideous and terrible of creatures, and when her tears for them fall upon them, their hearts are moved and their evil ways ended(for a little while at least).
The party is walking through the forest at night when they come upon a clearing. Half a dozen black-robed corpses lie scattered across the ground, and a pentagram of blood is shoddily drawn in the dirt.
It seems these people summoned something they could not control. Whether or not the demon returns is up to the GM, but it would be just as rich if the demon never returned, and for the rest of the night, every stray sound or odd shadow will be jumped at!
