Wars ravage planets and galaxies are slowly destroyed on by one. Living in a castle on one of Venus's moons is the moon's princess Asteri. She is good-hearted girl but a bit naive. She has an affinity for the arts and is a practicer of heavenly body magic, although she hasn't really delved into her magic's abilities thoroughly she has potential. Her father, the king, handles all matters in the galaxy in private, so Asteri is protected from the affairs of the outer worlds so she has no idea what is happening outside of her families kingdom.
