Hogwarts Expels Me? Devil of Azkaban

When the Cruciatus Curse became the prelude to his childhood, and when his Death Eater father was imprisoned, Karentheus Greengrass' magical path began in the abyss. The forbidden talent of improving magic spells at the age of five earned him the name "Monster" and also led to his ruthless banishment from Hogwarts. Five years later, in the salty fog of the North Sea, the iron gate of Azkaban reopened for him. The Dementors were afraid to retreat, and the Wizengamot was forced to compromise at Dumbledore's insistence - the devil who had been branded "dangerous" for studying dark magical creatures and touching the origin of the Dementors would return as a professor. What greeted him at Hogwarts was not applause, but fear and suspicion. The Daily Prophet calls him a "murderer" and the pureblood family sees him as a stain on their glory. However, when Quirrell's trolls run rampant in the castle, and when the shadow of black magic quietly seeps into the corridors, everyone will see what the real "devil" means are. When everyone thought Azkaban had left him nothing but madness, Karenius Greengrass would prove to the entire wizarding world with chilling grace that when the expelled genius returns, he will rewrite the rules.
