Gilgamesh

Gilgamesh is a colony world of the United Nations Space Command that is noted to have a brothel on its surface.

In 2552, an A.I. contruct, 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 the MJOLNIR shield 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.
