Resonance, as the Fallen understand it, are the remnants of the multiple levels of Creation that the Creator originally envisioned. In Paradise, each object existed in several states of being simultaneously, so a flame was also a mathematical equation, a song, a philosophical concept and a plant, all at the same time. This multi-existence was shattered during the Age of Wrath, when God, in His anger, touched Creation and broke it apart. Still, these connections linger as a form of sympathetic Resonance that connect things to concepts.
