Celestia

The plane of Celestia is known to some as the Angel Plane or, in the times of Seleucar, the Sacred World. Rarely have mortals had the chance to travel there. This home plane of angels is arranged in "spheres," from Aydin at the lowest to Empyrean at the highest. The Rulers of Celestia, the Hierarchs, reside in the Sphere of Empyrean.

The first mortals to visit Celestia were the Priests of the Ancient Church, who used special coronets to anchor their souls to their bodies, which were left behind. Though unable to even see the Angels at first, they revealed themselves to a Priest named Diale, who gave her coronet to Tamarin, the first Guardian Angel. From then on, it became customary for Priests to receive Guardian Angels.
