There is a place near old London town where seemingly Normal people congregate to abandon their mundane lives and problems. They call it the House of Sin, the man in charge is known only as the Mage. No one knows who he is or where he came from nor do they care. In the House of Sin, they are free to explore every desire, perversion and emotion, to be humiliated and dominated or to be the one cracking the whip, to become someone or something else, engaging in bizarre behavior that would not be at all acceptable in the real world.
