Nocturnum

"Nocturnum" is a campaign setting in the Call of Cthulhu role-playing game. It is one of the few materials produced for the ill-fated d20 version of the game. It was published by Fantasy Flight Games.

Plot

The story is set in the town of Snowflake, a small community somewhere in Colorado. The players are visiting the town for pleasure, for business, or are just passing through. The campaign begins on the road to the Clearwater Hotel, where the characters meet for the first time.

At the hotel, a woman named Cynthia Carmichael has been killed in her room, seemingly by a wild animal. The players investigate and are blamed for the murder by the local police.

In reality, Carmichael was killed by a werewolf named Ian McGuire, a slave to a Wilder Shk'ryth who plans to destroy the human race. He had been imprisoned in a nearby mountain for centuries by a local Native American tribe that had been performing a ritual to keep him trapped. He used Ian McGuire to escape.
