Power System (Resonance)
1. Resonance Core: Every Harmonic is born with a natural note, their starting affinity (e.g., Metal, Wind, Shadows).
2. Chords: By combining different Resonances, Harmonics create Chords (like combining Fire + Emotion = "Burning Rage").
3. Symphonies: At higher levels, multiple Harmonics can join powers into a Symphony, reality-bending performances that shift entire battles.
4. Dissonance: If someone pushes a Resonance against its nature, it corrupts, backlash that twists body or mind. (e.g., trying to force healing Resonance to kill someone).
