Early Life
Cassius Malfoy is a pure-blood wizard, born to a witch and a wizard. When he started attending Hogwarts, he was sorted into Slytherin house. Despite this, he was noted to be one of the most intelligent students in his year and many professors (and unbiased students) thought he would have made a fine Ravenclaw. However, due to his upbringing, he asked the Sorting Hat to put him in Slytherin, even though it was about to put him in Ravenclaw.

After Hogwarts
Cassius grew distant from his cousin Lucius once he graduated from Hogwarts. While Lucius became facinated with dark magic and the Death Eaters, Cassius was indifferent to the matter, and didn't take either side in either Wizarding War. Cassius got a job as an Obliviator at the Ministry of Magic soon after he graduated. After the Second Wizarding War, Professor Horace Slughorn went back into retirement, opening up the position of Potion's master at Hogwarts. Cassius applied for the job, and got it, making him the school's new Potion's Master and Head of Slytherin house. He soon became the Alchemy professor. He later became the deputy headmaster of Hogwarts.
