Darth “Cassandra” Slytherin is a mean cruel woman who is the Empress of the New Sith the owner of her Chamber of Secrets.

Darth Slytherin has her abilities as a Parselmouth and a skilled sorceress by her cobra staff.

She mistrusted Muggle-born to the point of proposing that they should not be accepted. When she expressed her opinions, she left the school, never to return, and constructed the Chamber of Secrets to house a Basilisk, so that one day, the Heir of Slytherin purge the Muggle-borns in her name, and fulfil her long-lasting wish of having only students with at least one member of the New Sith.
