Out from LPJ Design is Obsidian Twilight, a post-apocalyptic horror setting for the Pathfinder RPG. After being struck by a meteor, the world of Abaddon has been overrun by undead and is now ruled by the vampiric lich Calix Sabinus. The main book (PDF) contains new races, feats, spells, prestige classes, equipment, weapons, magic items, and monsters. As an accessory, LPJ Design also offers Ultimate Spell Decks: Obsidian Twilight Spell Cards, with spell details on individual cards—including ones for Animate Vermin and Anticoagulant.
