Eternal Sun

Eternal Sun, sometimes called the Keep of the Eternal Sun, was a plane of existence thought to be lost long ago but was found again after the Spellplague and became part of the World Axis cosmology model. In the Great Wheel cosmology, it was located in Mechanus. It was the divine realm of Amaunator, who dwelt in the Palace of the Four Suns with his exarch, Siamorphe. The Palace was surrounded by Waukeen's Marketplace Eternal.
