The Rule of the Spirits describes the era of the universes where The 11 Spirits secured the balance of the elements in the Chi World and The 11 Phantoms did so in the Astra World. Both universes underwent numerous vast changes, most notably on The World in the Chi Universe, and The 11 Levels of Hell in the Astra Universe. Many aspects of physics and magic were changed by the influence of The Priest in combination with the Titan Armor.
