"All magic around Britain flows into the ruling Monarch, giving them power and influence," Harry explained. "Through acts of reverence and worship, magical energy is literally expelled into a sort of energetic power grid that spans the country, and indeed, the whole world. There are points of ley line convergence, and swirling magical vortexes, where this power can be tapped into and manipulated or drawn out, but the knowledge of how to do it is protected by the Royal family. I only learned the technique properly when Elizabeth taught me some years ago."
