Discovery
It wasn’t the first time Harry was running from Dudley and his gang, but it was certainly the first time he didn’t know where he was.
As he had turned a corner down a little-used side street, Harry felt almost like he was shoved by the wind itself, which was nonsense, of course, the wind was in his face at the time. Granted, no one would call Harry particularly sane, after all, being trapped in a cupboard with nothing but the spiders and your own imagination took its toll on even the most stalwart of adults, let’s not think about a boy not yet out of single digits. The two sides of the childe’s brain warred, the logical, rational side scrambling for some reasonable answer, while the less sane segment was far too happy just rolling with life’s punches to put much thought into it.
Eventually, a mental compromise was made. The further discovery of what this mystical feat was, with a less than healthy suspension of reality for the duration of the testing.
It was then that Harry blinked, and where before he saw not much more than the average person; worse due to the stunted growth and the glasses, suddenly he saw everything in brighter detail.
Several days later, after having been locked in his cupboard for escaping Dudley, Harry felt a shock go through his arm, and he grasped onto the new sensation, and thus started his journey into a magics so obscure and unheard of, he may as well have invented it.
