Making an werewolf RPG
The town is called Westwick and its set in the 19th century. Players are townspeople of Westwick, which has a mayor who is distressed over his missing son.
You are part of the search party to look for the mayor’s son in the forest outside the town. Players need to do a Perception test to notice the monster hiding in the dark when the search party hears a strange noise.
And that’s all I got up to. I never wrote an RPG before. I got the fight scene down, and in the middle of the battle the wolf monster bites the head of the search team and turns into the mayor’s son when he dies. The players bring the corpse back and the leader is bitten and infected with lycanthropy, but you don’t know that yet.
