Orobelle is a principal character in Revolving Door who first appears in Chapter 2. Orobelle is The One Around Whom the Worlds Spin, the person who keeps the multiverse in existence.
Orobelle is also the Duchess of Diamonds, the second highest position in the Queendom of Hearts. Her bloodline was curated by her mother to position her to usurp the throne, and she was trained from a young age for that position. As a result of her upbringing, she is a deeply neurotic spoilt brat who throws around her forceful personality for petty reasons, affording little warmth to anyone.
