[Harry Potter] I Heard Hogwarts Has My Legacy

In 1888, I transferred from Raya Lucaria to Hogwarts School of Witchcraft and Wizardry. After countless battles, I became a master of Dark Magic (crossed out) Ancient Magic.

While researching Ancient Magic, I transmigrated again. I passed through the corridor and found myself a hundred years in the future.

"A dark shadow has fallen over Europe. The greatest enemy of the Wizarding World will return, guided by prophecy, and ascend to their throne..."

Wait, why does that sound familiar? The legendary villain is actually me? And what's with this era? You can be a Dark Lord just by knowing two spells? Then don't blame this master of ancient, primordial Dark Magic for stepping in.

P.S.:

1. It's been a long time since I finished Hogwarts Legacy, but I still decided to write this. The protagonist is a Slytherin undercover as a Gryffindor and a master of Dark Magic, the strongest there is, and the sort who'd rather fight than talk.

2. The related game is Hogwarts Legacy (HPL). There are a few spoilers. The protagonist's timeline goes from the Grindelwald era, to the Legacy era, to the Harry Potter era.
