Tiamat
The saltwater mother of all gods, slain and divided — the cosmos itself built from the body of the dragon-mother.

In the Enuma Elish, Tiamat is the primordial saltwater mother from whom all gods descend. When her children turn against her, she becomes the dragon of chaos; Marduk slays her and builds heaven and earth from the two halves of her body. Every Babylonian lived inside her. The epic can be held tenderly: the 'monster' is the primordial mother, and the story of her slaying is the account a new order gives of its own foundation — worth reading with eyes open to what was divided to build the world we know.
The SGE Reading
Shadow as origin-story: what a civilization slays and divides at its founding remains the substance of everything it builds.
Canon Resonance
The buried mother beneath the series' patriarchal institutions — the ground that remembers being a body.
