Eternal Sun was a plane of existence thought to be lost long ago[1] but was found again after the Spellplague and became part of the World Axis cosmology model. It was the astral dominion of Amaunator, who dwelt in the Palace of the Four Suns with his exarch, Siamorphe. The Palace was surrounded by Waukeen's Marketplace Eternal.[2]
