Astarion

The only former member of the Pantheon.

Some view him as being replaced by Trinity, though their purposes in life are very different.

Domains of Order, Light, and Knowledge

Focused almost entirely upon the preservation of the universe at all cost and would devote all of his focus upon anchoring all of the stars in place so that the Nothing, a strange inky black material separating patches of the Astral Plane without stars, would not someday grow to consume the world.

He does this through the use of the Masked One and the Starry Eyed, a guardian and a keeper intended to ensure these stars shall always be anchored in space by human perception.
