Utterly Mad

Do it. I got the tonsil stone, and my body is ready.

You know those black hole things? Well you have to walk into one of those at a specific place that has a large set of doors. Its to the right of the Grand Cathedral where you fight Vicar Camilia, past that church graveyard area and past the fatties and executioners. There by the doors a black hole will appear, walk into that and you're in for a treat.
