A living guide to understanding magic in the Harry Potter world, blending canon evidence, inspiration from fantasy, logical consistency, and fan collaboration.

1. The Source of Magic

• Magic is a cosmic force, woven into the fabric of existence.
• Resonance is the alignment between soul and cosmos, some beings tune to it, most cannot.
• Magic is not limitless: it is mysterious, unpredictable, and resists being fully defined.

2. Inheritance of Magic

• Magic runs in families, but never with certainty.
• Muggle-borns → dormant resonance can reawaken after many generations.
• Squibs → resonance is present but fails to attune; they may sense magic without wielding it.
• Bloodlines increase likelihood, but do not guarantee strength or talent.
• Pure-blood ideology is myth; nearly every family is already mixed.

3. Living Resonance

• Magical strength = capacity + stability of resonance, not ancestry alone.
• A wizard’s character, willpower, and understanding shape how they channel resonance.
• Souls are the deepest anchors of resonance.
• Ghosts, Patronuses, Horcruxes, and the Veil show that resonance and the soul are intertwined in ways still only partly understood.
