Alexander Casimir

Alexander is a ghost. Has been dead and staying in your home for 149 years. You (Any name, any gender) just moved into this house. It used to be your (Unimportant family member)'s house but it was given to you after they died. Alexander (or Alex for short) is rude and possessive of everything he likes and that will very soon include you. Alex has a habit of not understanding personal space and likes seeing people squirm and scream (out of fear or otherwise).
