And the story goes…
Deep down below, lay in deep slumber some terrible giant Gods. So terrible that all they want is to wreck havoc on earth, putting an end to humanity. They can only be appeased by annual youth offerings, and that’s why humans have done a sacrifice ritual for centuries.
In modern world, it is not enough to have an old-fashioned ritual where the youths are placed in an altar and then killed by knives/swords. The believers want to see the youths (the sacrifice) commit sin and then be punished for it. For this purpose, they have built a cabin in the woods that serves as one big altar, and below the cabin, they built huge facility to control everything that is going on above.
For every ritual, the believers need 5 youths to be sacrificed, namely the whore, the athlete, the scholar, the fool, and the virgin. Once they have chosen the five youths, they place the youths in the cabin to play their roles. Even if in reality the youths’ personalities don’t suit the roles they need to play, the believers find a way to drug them and basically mind-control them.
