Adoradores de Cthulhu

Adoradores de Cthulhu is a variation from the game system from Werwolf for 6 to 18 players.
One player is the guardian. He control the events in the Arkhan City, where each player has a secret role: cultists os citizens (some citizens with special powers).
The goal from the cultists is to kill every citizen, one by one. If they achieve these goal, then Cthulhu will come to our world.
The goal for the citizens is to kill all cultists.
Every round has a night fase (where the cultists kill one citizen) and a day fase where everyone (including the cultists) discuss and vote to kill one player.
