"Oh yes, it seems harmless. A slithering mass of bone and flesh, silent, motionless. Watching. It sits there, sleeping, two mandibles resting astride its face, two black pits where eyes should be with only a pinprick of light to show any life at all.
But the moment when you step out of line - and woe to you, if it is watching - those eyes will blaze with unearthly light and you will be defeated. From bone to bone teeth with emerge and your blood will be on its blades, and once your body wheezes its last breath your soul will be crushed and beaten, eternally strangled in the ever-present blackness."
