The Scroll of ErocEdit
The Scroll of Eroc was written by a Watcher philosopher named Makorameroc'Takalith. He wrote it when he observed an enormous light while stargazing on his home world. Upon staring at the shifting light, which happened to be Oaches in his pure form, he was enlightened and wrote the scroll.
Anyone who reads The Scroll of Eroc (without months of preparation) is driven completely insane. In order to become a Stierp, or high priest, of Oaches they must first go through preparation and read the scroll.
To prepare to read The Scroll of Eroc you must not talk for 6 months and 5 days.
