Tiamat

Tiamat is a primordial Babylonian goddess of the ocean and personification of chaos. She gave birth to the first generation of gods, and later, she was killed by the storm god, Marduk. From her divided body came the heavens and the Earth.

Myths & Legends
Tiamat originates from the Babylonian mythology. She was first mentioned in writer Berossus' first volume of universal history.

Enuma Elish
Tiamat is one of the two central protagonists of the Enuma Elish - the earliest recorded writing. In the story, Tiamat and her mate/brother Apsu/Abzu, embodied primordial nothingness. As they laid together they gave birth to gods, and from the gods, came creation. The gods started building the universe/reality. As being of primordial nothing, the very concept of creation hurt Apsu and Tiamat, disturbing their slumber. Tiamat ignored the fighting at-first, trying to get back to her sleep of oblivion, but Apsu would not ignore the commotion caused by creation and attacked the gods and earth.

The Gods fought and killed Apsu. Tiamat, enraged woke from her sleep and went to destroy the gods and creation as punishment for killing her beloved Apsu. She spawned millions of monsters - Dragons being the most prominent. Marduk, the strongest of the gods fought her. Only after an intense battle with the power of all the other gods behind him could Marduk overcome Tiamat and her brood. Apsu was thrown into the heavens and is the void of the night-sky. Apsu's corpse was the land and used as a foundation for Earth.

Appearance
Tiamat has the appearance of a dragon or a serpent. Sometimes, she is multi-headed, due to modern influences from the Dungeons & Dragons role-playing game.
