Welcome to the post-apocalyptic Purgatory Wars, where the battle over "harvested" human souls has destroyed Heaven and Hell. Sebastian, a young human tragically killed and unwillingly drafted into the war, is reunited with his deceased brother, Gideon, the most powerful angel in the Legions of Heaven, who plans to lead a coup to regain power and restore order. Realizing he holds the key to ending the war, Sebastian must face his brother, before Gideon destroys the cycle of life on Earth.
