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 PCs come across a wild thicket of luscious looking blackberries. They eat the berries and become drunken fools. Later they find out that the berries were part of a fae garden and were intended for fae wine. In payment for stealing the berries, the mischievious fae make life inconvenient for the PCs. Horses are untied, water skins are drained, spare clothing is drug into the water, etc.
