Obsidian Twilight
A dark star has struck the world of Abaddon, triggering ecological and eldritch destruction. Endless twilight now covers a ruined land ruled by the vampire lich lord Calix Sabinus, while ghouls, demons, vampires, and other undead creatures prey on the survivors. Players create heroes and undertake adventures in this post-apocalyptic survival-horror setting. The book includes eight playable races, new feats, spells, prestige classes, monsters, regions, history, and organizations for campaigns focused on resisting the forces that dominate the shattered world.
