Intro. Resonance is the bond that forms between a Kindred and a Custodian, a synchrony between their souls that allows for transformation and combat. It's not just technique, but a shared emotional and mental frequency: when both are aligned, power flows stably; when not, it becomes uncontrollable and dangerous. The Resonance cannot be forced, it is born from a real compatibility and affects both equally, transmitting pain, fatigue and emotions. The deeper it goes, the greater the power it grants, but also the greater the risk, as a break can lead to the Kindred's corruption or the Custodian's total loss of control.
