From the Core of Aesontis comes magic, Resonance. A power of infinite abilities, woven to endless ends by the Resonators across the globe.
Resonance is volatile but, when in the form of a core, it can be wielded safely. The Seven Cores are that stability, offering seven different abilities to Resonators.
The nuances of the Seven Cores brought to life by Harmonics, restricting Resonance into derived forms but granting great power to each Resonator.
As explained by Rebbi Kuntza, the Izpako-Denrola Effect tells of the history that brought about the decline of the Cores of Time and Space.
The untapped fountains of potential, lacking control over their own Resonance.
Those who twist Resonance to become their own, marking their bodies with the signs of the seven. Resonex rise, filling the air with Resonance and brining terror down upon Aesontis.
