A Certain Half-Blood Prince of Hogwarts

That year, Voldemort had just formed the Death Eaters and was about to usher in a bloody era in the wizarding world. The Marauders, the F4 of the Marauders' Era, had only just started at Hogwarts and were eager to dispense justice. Pure-blood ideology was rampant. Malice and fighting among students were more than ten times worse than in the era of the Chosen One! In these circumstances, Eric joined Slytherin under the name Severus Snape. Outside, the Death Eaters watched like hungry wolves. Inside, a blond-haired boy had his eye on Eric's childhood sweetheart! But Eric merely sneered. He looked at the many gleaming golden traits and talents on the Hogwarts students and teachers, then at the Replication System in his hands. His smile grew increasingly unhinged! This is a story set in Hogwarts during the Marauders' Era, and a story of the protagonist plotting his way step by step to the top. Slow burn, slice of life, no saintly hero, nearly invincible.
