NOT a crossover. Harry's magic, to minimize his injuries at the hands of his relatives, boosts him by mimicking the powers of Spiderman. I hate wounded duck heroes, Harry learns about Wizards with confidence, a keen intellect, and knowledge of history. Wizards are stuck with Victorian traditions harems, slavery, dueling the method of conflict resolution.

A simple question from Harry during his vault visit in book 1 changes his life, as Harry accesses a family vault. And a stone there that will change his life, even more than finding out he is a wizard did.
