HP: the Dark Lord from Gryffindor

Cassius, the nephew of Moody, gained an exaggeratedly powerful soul. The powerful soul gave him the abilities he dreamed of. Cassius decided to use this ability to bring a grand gift to the world. This time, everything will go according to Cassius's ideas! Voldemort: Everything is going well with the plan, but why do I always feel like something is weird? Dumbledore: Why don't you just tell me how many backup options you have. Harry: Just listen to Cassius! Cassius: Voldemort? It's just part of the plan~ (Purely written for fun, updated from time to time, welcome to keep books, just leave them on the bookshelf to gather dust)
