Remnant

A form of pure energy with complete frequencies. The information it carries transcends time and space, enduring in a stable, unchanging state.
In their studies of Waveworn Phenomena, scientists discovered "Tacetite"—a substance that can permanently hold Remnant Energy. The Tacetite can be made into potent weapons for Resonators to combat Tacet Discords. Transdimensional spaces where Remnant Energy is abundant are known as the Sonoro Spheres.
