It is night and it is raining, you’re driving along a road in the Fairgaig forest near Loch Ness lake, when your car stops.
Looking for help, you see a house nearby: it seems abandoned, but there are some lights inside. 
The cemetery overlooking the entrance doesn’t seem to scare you, but if the name of Aleister Crowley tells you nothing, only once you set foot inside you will understand what you are going to face.
