An innovative and interesting take on creating new and quick religions on the fly for your NPC cults and enemies. A very well thought out solution to the old deer caught in the headlights problem of coming up with a cult or group during play with details right then.
The ideas for this system are well thought out, for a free system this one is a solid hit for DM who needs or want religions during play for adversaries, enemies, allies and more. I can see using this pdf for everything from a Call of Cthulhu style horror game to a D&D style adventure with a slant of cults and deities. My advice here is to grab this resource yesterday and let fly with the dice to develop some nice setting backdrop details for your PC's.
