The world of Tir Na Nog was brought to prosperity by Chiral Particles, which produce infinite energy. It eventually led to the development of the weapons called mirrages, wielders of whom are called mirrists, and eventually the Kaleidoscope, a fearsome weapon that could deplete the anima at the hearts of people and materials and turn them into light. Overuse led to anima separating from the world itself, turning all to dust. Repentant mirrists oversaw Project Aegis to revitalize their dying world. Years later, Tir Na Nog has returned to a verdant land, but one day a storm of meteors takes out the island home of Ix Nieves and Mileena Weiss. Surviving by pure chance, the two are taken in by the Salvation Front and discover a grave new threat to their world.
