Eleusis is a planet in the Olympian Galaxy. Formally under the rule of Hephaestus for thousands of years, it was ignored by him for enough time to allow something very close to religious freedom until the fall of Demeter.

In the scramble to conquer her domain, Hephaestus battled Artemis on Eleusis causing extensive destruction (Beyond The Impossible 81).

Eleusis joined the Alliance during the Mortal Rebellion and became a founding member of the Mortal Republic.
