In AD&D's Planescape setting, Elysium is the plane of true Neutral Good. There are four layers, named Amoria, Eronia, Belierin and Thalasia. Thalasia is a great shallow ocean, while Eronia and Amoria are both rolling landscapes. For some reason, the guardinals who dwell on the plane don't like to talk about Belierin. Sumerian, Babylonian and many other gods live here. One notable location is the City of the Star, home to the goddess Ishtar.
