A character with a celestial bloodline can trace her heritage to beings of the Upper Planes, much like an aasimar or celestial creature. Most angels, archons, guardinals, and eladrins have the ability to interbreed with humanoids, and examples of celestial creatures descending from the heavens to live with mortals often appear in myth and legend. Descendants of such relationships often have silver or golden hair, a proud bearing, or a piercing stare.
