Mystic, despite being relatively sheltered, is actually pretty personable. He does have a hard time making friends, and has a lot of anxiety about being outside. Luckily, he has a great support system.
He spends most of his time doing art and creating worlds to play O&O in. Mystic is autistic and has a special interest in Ogres & Oubliettes (pony dungeons and dragons), so he loves to run campaigns and play in them with his friends.
Sometimes, he also gets small flashes of things before they happen, but… everyone has those, right?
