The Netherworld (Land of No Return)
A dark house where the dead eat dust — no heaven, no hell, only the long shadow beneath the earth.

The Mesopotamian dead went down to a grim underworld — the 'land of no return' — a dark house beneath the earth where the dead eat dust and clay and dwell in shadow, ruled by the stern queen Ereshkigal and her consort Nergal. There was no bright paradise and no fiery hell; nearly all the dead shared the same dim fate, their comfort depending less on virtue than on whether living descendants maintained their funerary offerings. This sober vision — death as a shadowy, irreversible descent rather than reward or punishment — shaped much of Mesopotamian reflection on the brevity and preciousness of life.
In short
The Mesopotamian land of the dead (Sumerian Kur / Irkalla; Akkadian erṣetu, 'the earth/underworld'), a dark, dusty 'land of no return' beneath the earth, ruled by Ereškigal, where all the dead share a dim, shadowy existence.
Where it’s found
'Inana's descent to the nether world' (ETCSL 1.4.1); 'Gilgameš, Enkidu and the nether world' (ETCSL 1.8.1.4), both in corpus; the Descent of Ištar and 'Nergal and Ereškigal' (akkadian-pending)
How the idea developed across Sumer, Babylon & Assyria
Sumerian Kur/Irkalla and Akkadian erṣetu describe the same shadowy underworld across the strata; Ereškigal rules, with Nergal joining her as consort in the myth 'Nergal and Ereškigal.' The dead's comfort hinges on the living's offerings (see kispu), not on moral judgment.
