Each god brings its own madness. To know the god - to be accepted by it, to feel its mysteries - well you have to let that madness wash over you, and through you. This isn't in the books of magic. Why? For one thing, it's all too easily forgotten, and for an other, you have to find it out for yourself. And for those who would sanitize magic, whitening out the wildness with explanations borrowed from pop psychology or science - well, madness is something that we still fear - the great taboo. So why did I choose Cthulhu - High Priest of the Great Old Ones - lying dreaming "death's dream" in the sunken city, forgotten through layers of time and water? It sounds so simple to say that I merely heard his "call" - but I did. Gods do not, generally, have a lot to say, but what they do say, is worth listening to.
