Arthur

Arthur is a ghost, and the older brother of Bobby. Formerly a nasty poltergeist, Arthur was partly reformed by a term of (punitive) guardianship, but remains a sullen and reluctant presence all the same.

Arthur is unique in being the first recorded instance of a "demon portal"--a human spirit capable of being actively possessed or forced to action by a demon. The reason for this state is as of yet unknown, but his situation is a regular source of headaches as the topic is explored.

Personality
The picture of a spoiled rich boy, Arthur is a bully by nature, his inferiority complex leading him to try and drag others down to his level. He's prone to sudden mood-swing, his behavior often erratic as a result. Some of this is due to apparent mental illness; the rest is just because he's a prick. A bit of a control-freak, Arthur dislikes being commanded, and habitually talks down to folks, often forgetting he is not the most important person in the room. He is becoming accustomed to being reminded of the fact.

Though a challenging presence to deal with, Arthur is not all bad. He is dedicated to his younger brother, to the exclusion of all else. He regularly considers how his actions will impact him, a practice that helps him self-regulate. If shooting his mouth off would upset Bobby, Arthur will bite his tongue. His loyalty, once earned, is permanent. Assigned a task, he will complete it out of spite, if not duty. And, for what it's worth, he's not bad looking--which justifies a lot of unfortunate things.

Trivia

 * Many of Arthur's uglier quirks stem from undiagnosed mental issues carried over from his life. With no access to help and no coping skills, he is at the mercy of an ever-changing mind-state, freely swinging between states of mania and depression on a whim.
 * Arthur has been extremely homophobic in the past. Turns out, this is partly out of self-hate, as he is solidly in a closet he refuses to recognize. He's getting better about it--mostly because he's tired of having his nose broken. It has been a slow process.
 * He can be a little creepy. He has a staring problem, and has been caught watching folks--Ravyn included--while they sleep. (Ravyn corrected this about how you'd expect: with a fist.)
 * Ravyn's relatively moral but no-nonsense presence has inspired recent attempts by Arthur to curb his more destructive behaviors. It's a process, but he's trying, if only to make a better impression.
 * Bobby is probably the only person Arthur has ever loved. Though flaky and passive-aggressive by nature, he will jump to Bobby's defense in a heartbeat, no matter who's on the other side of it.
