Gallu

In the Sumerian myth of the Descent of Inanna, when the goddess descends to the Great Below, she is accompanied on her return by gallu demons who are assigned to take a substitute back with them. They are described as beings who 'know no food, who know no drink, who eat no flour offering, who drink no libation offering, who accept no pleasing gifts.' They are relentless and without pity.

Depicted as grim figures who could not be appeased with food or gifts — they were enforcers of death's claims, not beings with human desires. They carried rods and rings as symbols of authority over the dead.

Could drag any living person claimed by the Underworld down to death. Could not be distracted, bribed, or appealed to emotionally. In myth they travel with the dead and prevent their escape from the Underworld.
