Dweomerheart

Dweomerheart was the home plane for Faerûn's deities of magic. It appeared much as a glittering city set on a high plateau. Much of the city was built from pure magical energy.

Dweomerheart had no known portals that linked it to any other plane.

Dweomerheart was destroyed in the year 1385 DR. Though the deities of Dweomerheart largely perished, most of the Faithful of Mystra, Azuth, and the other gods dwelling there were transported safely to the Fugue Plane where they were restored, many of them ending up either in Towers of Night, Gates of the Moon, or Kelemvor's own City of Judgment.
