Cimorene is the 16-year-old princess of Linderwall who vehemently rejects traditional fairy tale expectations. Preferring Latin, fencing, and cooking over passivity and helplessness, she runs away from an arranged marriage to volunteer as a dragon's captive. She is highly practical, sharp-witted, and firmly dedicated to carving out her own unconventional path in life.

Kazul is a pragmatic, large green-and-gray dragon with three horns who resides in the Mountains of Morning. Unlike other dragons who expect princesses to act helpless, Kazul appreciates common sense and gladly takes Cimorene on as an assistant. She is well-respected in dragon society and possesses a sharp, observant mind.

Zemenar is the newly elected head of the Society of Wizards, easily recognizable by his waist-length grey beard. He relies on people's belief in traditional stereotypes to manipulate them, actively seeking to drain magic from the environment and ancient artifacts for his own gain.

Antorell is a wizard with a long brown beard who directly assists his father, Zemenar. He is arrogant and dismissive, particularly toward those he views as helpless princesses, and frequently ventures into restricted dragon territory to further the wizards' ambitions.

Alianora is a blond, blue-eyed princess from a neighboring kingdom who serves as the captive of the dragon Woraug. Although she appears to fit the stereotype of a helpless royal, she accidentally subverts traditional tropes at every turn. She quickly bonds with Cimorene over their shared feeling of being outsiders in a rigid society.

Morwen is a calm, highly knowledgeable witch residing in the Enchanted Forest. She sports wavy ginger hair, black robes, rectangular glasses, and an entirely practical approach to life. Maintaining good relations with dragons, she keeps a neat house and holds zero patience for foolishness or artificial social rules.

Woraug is a prominent dragon in the Mountains of Morning who holds Alianora as his captive princess. He is traditional and adheres strictly to the established rules of dragon society, holding strong opinions on what constitutes "proper" behavior for both humans and dragons alike.

The Stone Prince is a practical royal who managed to halt a magical petrification process by plunging his arms into the Waters of Healing. Fleeing the heavy expectations of a prophecy, he retains his mobility and speech despite being half-made of stone, offering a pragmatic and observant perspective to his new allies.

Therandil is a prince who blindly follows fairy tale expectations and societal norms. Believing it is his sole duty to rescue princesses and slay dragons, he stubbornly attempts to "save" Cimorene from the Mountains of Morning despite her constant refusals. He is earnest but entirely lacking in common sense.

Moranz is a prideful dragon who recently suffered embarrassment when three captive princesses ran away from his cave. Highly defensive about his reputation, he attempts to catch other dragons' princesses acting improperly to make himself look better by comparison.

Keredwel is a traditional captive princess who firmly believes in adhering to fairy tale tropes. She expects a life of weeping and eventual rescue, becoming deeply appalled by Cimorene's lack of despair and actively bullying those who deviate from expected royal behaviors.

Roxim is an elder dragon in the Mountains of Morning who appreciates common sense above strict tradition. He serves as an experienced figure within dragon society and acts as a reliable contact when other dragons need assistance or important messages delivered.
