I've been watching some old series of late, and started up xfiles a few days ago. Started with a feature film that talked about an alien disease that would be the ultimate plague, and how the world of man would basically end in 2030. But then i started binging the series again.

S2E14 touches on the satanic cult effect, the ritualistic rape and sacrifices of children in such scenarios, "american stonehenge" (Georgia guidestones), and how people of power at the school in the small town it is filmed in have faith in the devil.

Key elements from the episode (spoilers):

1. Blood of the young is very powerful
2. "do what thou whilst" is mentioned (Alistair Crowley's rule one)
3. The name of the school is Crowley Elementary
4. The witch (Mrs. Paddock), responsible for the deaths of two students, has a pet snake that eats the one who betrays the local sect, and she winds up being show with snake's eyes (an homage possibly to reptilians)
5. The original sect "lost its faith" and the witch punishes them by killing the original sect using black magic, then vanishes

Will keep watching to see if another hint of what they do comes out from this series in particular.
