Samhain

The entity that calls itself Samhain (pronounced: 'SAH-win') is a primordial force of pure fear who has based itself around the celebrations of the holidays that bare similarities to All Hallow's Eve (or Halloween). It is usually harmless if the ancient superstitions of the holiday are obeyed but will occasionally see fit to torment humans for either defying the rules or usually for its own amusement. It can take many forms and can put numerous humans or animals under its mind control. A favourite form would be either a thick orange mist or a pumpkin-headed wraith.
