Aos

Marcus awoke on a planet far different from the one he died with magic, strange creatures and a vastly different sky. Aos has a pale red planet, revealed to be a moon by the author, several times bigger than Earth's Moon visible in its sky and at night two others take its place, one small and pale blue (sometimes appearing white) and the other medium sized with a green hue (sometimes appearing yellow).
