Celestian

Celestian was a deity from the world of Oerth  revered by planewalkers and wildspace wanderers. He was one of the major powers worshiped on the Rock of Bral.

Description
Celestian was portrayed as a black-skinned man who traveled the skies.

Worshipers
Celestian appealed to good or neutral worshipers who never liked to settle down—not even in a single plane of existence or crystal sphere. The Far Wanderer's presence in the Astral Plane meant that his clerics had a major advantage over those of most other deities, in that their divine magic did not lose power wherever they might go in the Outer Planes, since the Astral bordered all of the Outer Planes of the Great Wheel.

Celestian's holy symbol was a black circle with seven stars.

Divine Realm
Ever the wanderer, Celestian did not even maintain a divine realm. Instead, he traveled from place to place within the Astral Plane. His petitioners, without a divine realm to inhabit, instead became the stars of his black robes, until finally merging with his essence.

Relationships
Celestian got along well with many gods of travel from other pantheons. Similarly, he was strongly allied with his brother in the Oerthian Pantheon, Fharlanghn. He was working to establish his brother in the planes beyond the world of Oerth.

History
On the world of Toril, Celestian played a significant role in the Time of Troubles by agreeing to transport (a now mortal) Waukeen from Toril to the Astral Plane so that Ao would not discover her leaving. (Her plan was to make her way from there back to the Outlands, but because of the machinations of Graz'zt, she was instead trapped in the Abyss for many years.) Celestian had owed her a favor, which was why he agreed to her plan, but he refused to also transport her ally Lliira, whom he did not know.

Towards the end of the 13 century DR, though Greyspace itself was said to be "dying", Celestian was beginning to gain so many new worshipers among the various planes of existence that some scholars postulated that he might soon be elevated to the power of a greater deity.
