Tom Marvolo Riddle, a game character created by a TR fan, transmigrates into the world. As he struggles to adjust to a life no longer controlled by anyone, people suspect he is another incarnation of the Dark Lord. A thoroughly bewildered Dumbledore keeps a close eye on him, while the wretched, overworked Professor Snape provides close protection (and training).
Dark, expressionless, slow on the uptake, silence is golden, full of inner monologue, indecisive, Avada Kedavra at Jerry, Lord.
A Dark Lord sorted into Hufflepuff who is determined to lead his house to glory. He loves food and magical creatures, and is skilled at using the Unforgivable Curses, Fiendfyre, and Snape's own Sectumsempra. Dumbledore is so shocked that the pile of cockroaches in his hand drops to the floor.jpg.
"Oh, you can't use the Unforgivable Curses at Hogwarts? That's not how I remember it." The little Dark Lord is expressionless and obedient.jpg. "Did I do something wrong?"
Snape's lips twitch. "No, you did nothing wrong, my lord. No one said you were wrong." No one ever said it was wrong to use the Killing Curse on a mouse, either.
A naturally dark, obedient(?) young master who sometimes doesn't even know what he's doing when he throws his weight around (because of the soul fragment's influence), living in chaotic circumstances with Voldemort's most loyal, capable traitor of a servant and a master of honeyed words. They're forced to share both a home and a school.
Also known as Severus Snape's Ordeal.
The male lead isn't actually Voldemort. At most, he's an NPC who has awakened to self-awareness, but he's still pretty powerful.
Also, his mental age isn't that of a child. He just isn't used to expressing himself, and isn't used to Hogwarts without Avada Kedavra flying everywhere.
