Cosmos is a short statured, feminine male with vitiligo. Purple eyes, seemingly caused by his magic, seem to glow in the moonlight, the very source of his magic. He was born with vivid red hair he got from his mother. He worships the goddesses Hecate and Selene, Hecate for the magic he was blessed with, and Selene for the very fact she's the goddess of the moon, once again the source of sorts for his magic.
