In Harry Potter with shadow Magic.

I just came up with this Idea while online classes so don't expect some planed story (at least not at the start). Sorry for all the mistakes I'm gonna make but English is not my first language. The Mc (Rian) is not from another world, which means he has no idea, what the shadow magic can do. ________________________________________________________________ Rian is a descendant of all four founders of Hogwarts and has a large Mana core and great control over his magic, but a certain old Goat Fucker didn't like that, and sealed Rians Magic for 'the greater good' and made him a squib at the age of 3. But he didn't notice the accidental magic that young Rian performed to store Half of his Magic in his shadow... ________________________________________________________________ If you want R-18 Chapters write ideas in the comments, but nothing before young Rian is at least 14. Nothing in this story is owned by me exept my own characters
