Y'golonac is a horrible entity trapped behind a brick wall under the earth, destined to once more roam the world, killing, raping, and doing whatever it pleases once more. The fufiller of all desires. The Violator. The Defiler. Anyone who reads it name or hears it aloud is subject to possession by it. Yep, you're pretty fucked.
Wait a minute, the bastard can possess me now that I've read this? What the fuck! People want warning labels on a Big Mac, and there isn't even a forward about Y'golonac in this thing? What the HELL?
