Hogwarts: The Strongest Hufflepuff Senior

Plum transmigrated into a baby's body and was tragically made the sacrifice for Voldemort's creation of a Horcrux, Slytherin's locket. He barely survived, only to discover, tragically, that he was an Obscurial. Worse still, he grew up in the same orphanage where Voldemort had spent his childhood... To keep his Dark Lord buffs from stacking up until he became the next Dark Lord in Dumbledore's eyes, all he wanted was to keep a low profile and grow quietly in this magical world. But to resolve the Obscurus inside him and stay alive, he inherited Slytherin's legacy and brought bloodline magic to new heights. His power no longer allowed him to stay under the radar...

Why does the Slytherin family have a bloodline inheritance of Parseltongue? Why does the Dumbledore family have the favor of phoenixes? The petrifying gaze of a basilisk, a phoenix's ability to be reborn in flames... As Plum gathers bloodline powers, he encounters all kinds of people and events, and a different magical world unfolds before him! Do Slytherins really hate Muggle-born wizards? Is the side effect of a Werewolf bloodline truly incurable? Why did Voldemort have no nose? How are alchemical creatures created?...
