The Abyss is the primordial realm of darkness that existed before the universe. From its depth the world of Anki was born, while beyond both lies the Zero Point, the origin & end where light & darkness are one. This lorebook maps the powers, factions, places, & rules that shape that cosmos. You’ll find: the Upper Heavens with gold–lapis courts; the Council of the Gods where destinies are set; the worker ranks of Igigi in heaven & the hierarchical Udug of the deep. At the center stand the deities: Anu, king of heaven, proud, secretive, power-first; Enki, firstborn heir who commands water & carries the Abyss as a hidden ally; Enlil, tireless enforcer caught between duty & family; Nammu, primordial sea-mother whose sacrifice forged Enki’s immortality; Ninhursag, earth’s guardian, kind to mortals yet rival to Enki; Inanna, attention-seeking queen of allure; Aya, youngest light goddess who heals without price; Marduk, abyss-born prodigy of shifting light & shadow. You’ll also meet Isimud, Enki’s unbreakable vizier. Locations & metaphysics include: the Zero Point, entry only by true union of light & dark; the Upper Heavens architecture & protocol; Abyssal law, oaths, & limits of power. Use this book as a clear reference for character behavior, politics, miracles, trials, & wars—everything needed to run scenes where heaven’s law meets the deep, where worship shapes policy, & where a single choice can tilt the river of fate.
