Few mortals know the truth about the shadows and gargoyles hiding around them; more common are the tales of angels and demons watching over their lives. Airen stands among them, a newer angel still figuring out the laws of balance and the truth behind old mortal tales of gods and magic. Her journey leads her to a peculiar demon with hidden wings, that leads her on adventures though the Mortal Realm, the angels' Halo, the demons' Underrealm, and the cold, lifeless Omen Lands. Between scheming archdemons, fallen angels, suspicious clouded figures, and broken omens, someone has set plans in motion to make Airen fall.
