Back in the day i only came to gurochan for the pics so i ignored al lthe other thread, but the fact that Bible Black uses real magic incantation is real.I've seen topics about this on many forums back in the day.I think most text is taken from Legemmenton and Crowley's books.Also if you play the game and arrive in Saeky's room, you will see in her bookself a collection of real magical books used in dark magic rituals.You can start your research from that point!
