“ Ursula is a were-bear; she and Stewart, the bailiff of a rural feudal estate, are lovers, sharing all their secrets as lovers often do. Recently something has been taking livestock. *He* must deal with suspicions that a bear is involved (one has been seen nearby...): *she* must defend herself if it is revealed (perhaps by a jealous suitor, perhaps accidentally) that she is a lycanthrope. The adventurers might be called in to track the hungry beast(s) and discover her secret, but be able to reveal that the culprits are a small pack of wolves that has moved in to the area. The adventurers might earn the gratitude of both Ursula and Stewart, depending on what they reveal, and to whom.”

If you get high enough, (meaning you get enough new members) you start to enjoy the benefits. Maybe a willing sacrifice is much more effective for the transfer. But no one says, that a suddenly unwilling member, threatening to tell the authorities, may not loose it involuntarily... thus start people to vanish, and aged corpses are deposited somewhere safe.”
“ Village has a nearby natural substance that comes from the ground and burns well when lit. They use it only locally and try not to let the secret get out.”
