The Place: Fantasy version of Russia, winter.
The PCs want to cross a river to get to town, but the local rusalka won't let them. She's been wronged by men her all life and now won't let any man cross the river in which she drowned. The PCs, being travelers from a distant land, are eager to prove to her that not all people suck and ask her for a quest to prove their worth. She tells them that she was kicked out of her home in winter along with her baby daughter and wants nothing more than to be reunited with her child - something that can only be accomplished if the PCs get her the bones of the dead child.
|Are you positive this is your villain?|
The PCs go to the death site and find a gnoll camp there. The leader of the gnolls is a fierce werewolf wielding a flail that can fell trees. They charge screaming bloody mayhem. There is a bloody battle and the PCs eventually defeat the gnolls and their werewolf leader and start looking for the old bones that will reconcile the rusalka. Meanwhile, the dead werewolf returns to its human form - a young woman remarkably similar to the rusalka.
|Gnolls eating dinner, an activity deserving termination with extreme prejudice|
Questioning a wounded gnoll, the PCs discover that the gnolls found a dead woman and a living baby. Believing the baby had killed its mother, a great honor in their culture, the adopted it and raised it to be the scourage of their canine deity, who in turn blessed the child with the gift of lycanthropy. At this point, the truth downs on the PCs.
Not even a bit crestfallen, and lacking any semblance of tact, they come to the rusalka and tell her "eh, we found your daughter, but we had to kill her, because she was a werewolf... sorry about that."
At this point the rusalka wails about how incredibly cruel they are - to give her hope, just to dash it. Frothing and raging, she swears that she won't let anyone ever cross the river again.
Also, to remove concern from you heart - this was not a game with kids.
