CAIN: Book of Leviathan

An expansion for CAIN, a narrative roleplaying game from Tom Bloom (Magnagothica Maleghast/Lancer RPG), including the optional rules, abilities, NPCs and lore for a dark, looming shadow over the titular organisation - where even the dogma and wrath of CAIN cannot strike out and erase their influence. Even darker dissent looms from Leviathan, a psychic order empowered by figures imitating the Four Horsemen of the Apocalypse, and commanded by forces beyond the waking world.

Includes:

- Five new bonds/abilities controlling gifts granted by the Horsemen. One for each scion of the Apocalypse as well as an additonal bond for the Choir, whose hymns mark the Horseman's arrival, and direct Leviathan's influence upon the world

- Related mechanics for these bonds, the Original Sins, involving Sin management and sacrificing your own humanity for a greater power over the forces at your disposal.

- NPCs and Combat Encounters from the organisation's own ranks, including Leviathan's inhuman 'Men in Black' homonculi known as the Agents, and the Animals - the Leviathan's own version of CAIN's exorcists. 

- An expansion to the Possessions and Occult/Medical categories. As well as an in-deployment tradesman NPC willing to offer up items to the exorcists in return for bodies to shepherd to the afterlife.
