(Translated & abridged) Publisher's blurb
Incarnate a hero dedicated to a powerful pantheon, as well as one of these gods in the World, the sword & sorcery universe of Enemy Gods !
If you are a god, you need a hero to advance your cause with the mortals. Most players will take a hero and a god that get along very well, but more audacious players will go as far as to make hero and gods mortal enemies.
