Physical Description – Mavis is the kind of person you would notice if she were in the room. She has cold grey eyes, short, silky black hair cut in a wolf cut. She prefers to wear loose, baggy clothes. She’s seen wearing a small locket in the shape of a dagger and carries a black umbrella with her all the time.

Mental Description – Mavis looks intimidating at first glance. She can be described as cunning, confident, funny, sharp-tongued, and is known for having a very short temper. She’s a bit of an overthinker and very mature for an 11-year-old. She might look like she doesn't care at all, but she is highly alert to her surroundings and might eavesdrop without trying. She is extremely claustrophobic, and she panics easily in closed places.

Biography – Mavis Blair was born on the cold night of August 24th. Her parents were Damion Blair and Isabeau Blair (nee Beaumont). Her mother is from France and had to move to England for business purposes. The Blairs were known astronomers while having many connections with powerful wizarding families all over the world. Their Mansion is not entirely known to their heirs as well. They were extremely secretive. One of their such relationship included the Nygaards of Sweden (dnpc family as of now) and their heir, Arvid. He was Mavis's only friend when she was younger, but soon, at the age of 7, he moved away to his homeland, Sweden.

FIOM – When Mavis was exploring the Blairs’ Mansion at the age of 7, she entered a tiny broom closet, and the door immediately closed behind her. She panicked, and she slammed the door harder and harder, but no one heard her cries for help. She gave up after a long 15 minutes, weeping in the same closet she got stuck in, and the door opened by itself.
