The Book of Madness
"The Darkness Has Teeth... And it Hungers. Beyond the Horizon, dark forces claw at the edges of sanity, battering at the fabric of reality, seeking final night: Nephandi, the Corrupters -- Marauders the Foot-Soldiers of Chaos -- Demons, the Renders of Souls-Paradox Spirits, the Mage's Bane -- Umbrood, the Living Mysteries. What are they? Why are they? Can we stand against them at all? And what if we cannot? The Book of Madness is a bestiary for Mage: The Ascension, exploring the darker reaches of magick's touch. It presents the forces of Chaos itself, for players to fight and Storytellers to champion".
