When Harry Potter wasn't the Harry Potter we know:
He is a standard Slytherin, the third generation leader of the Death Eaters, and the potion master;
Born into the Potter family, a Ravenclaw family;
Both parents;
Godfather Sirius Black, a pure Slytherin;
The youngest Potions Master serves as a mentor, and the second generation Dark Lord teaches magic.
Such a Harry Potter accidentally came to the original world and became the "savior" because of making the potion "Hela's Smile". The trajectory of his destiny has shifted. What will happen to all this?
