Gilgamesh is a human colony world. It is a lawless world, mainly controlled by mobsters and Insurrectionists, and is relatively obscure as a result. The planet has a large and refined brothel on its surface.

In 2552, the AI construct Cortana wired a transfer of funds to the Gilgamesh brothel, masquerading as Colonel James Ackerson. This was her form of payback for his heavy-handed attempt to make sure that Dr. Halsey's MJOLNIR AI-Spartan integration test failed. Since the brothel would send a confirmation of this action, she knew that this action would make his wife quite mad and in turn disrupt his life.

Gilgamesh apparently still existed during the Battle of Earth, as evidenced by active transports from the colony to the Quito Space Tether.

Trivia

Gilgamesh was a Sumerian king that ruled Mesopotamia (specifically Assyria) circa 2650 BC. He was the Sumerian equivalent to Hercules, as he was considered a demigod of superhuman strength.
