HEROES OF IMPILTUR
Celestials have existed since nearly the beginning of the universe, originating on Elysium in the Astral Plane. The Blessed Fields of Elysium is a strongly good-aligned plane of existence. Elysium is a plane of idyllic good and the destination of souls who sought to further the cause of good. Elysium is home to many celestial creatures, including the Guardians; a race of celestials native to the plane. In times of need, these creatures are sent out into the worlds by higher powers to aid in battle against the forces of evil. At the beginning of time, several powerful and wise Guardians decided to remain on each of the various worlds to watch over them, becoming the Celestial Guardians. Each chose to take the form of a large animal.
