Jar'rat/Sarah, the red Goddess of Gye'in and ruler of dusk and dawn.

Her pelt bares fur, scales, feathers, and skin. When one looks through her left wing, they see the light of day. When one looks through her right wing, they see the darkness and stars of a moonless night. The crest upon her head gives off the light of a red sun at its birth and death.

When she crosses her wings over each other, the sun eclipses.

On the festival of the gods, she descends from the heavens and dips her tail into the sea so her brother can climb up it and leave the water.

(She's a character from my fantasy universe, Gye'in)
