"Remember always to copy each of the formulae as I have put it down, and not to change it by one line or dot, not so much as a hair's breadth, lest it be rendered valueless, or worse: a broken line provides entrance for those Outside, for a broken star is the gate GANZIR, the gate of death, the gate of shadows and the shells."
Quote from the (Pseudo-)Necronomicon translated by Simon from "The Mad Arab"
