Aerin is the teenage first sol, or princess, of Damar. She is an outsider in her own court due to her pale skin, red hair, and her late mother's reputation as a witch. Lacking the magical abilities common to the royal family, she struggles with feelings of inadequacy. She compensates by turning her attention to ancient lore, horseback riding, and experimenting with a protective ointment called kenet to hunt dragons.

Tor is the first sola, or male heir, to the Damarian throne. He is Aerin's cousin and one of her few genuine allies at court. Heavily burdened by his royal duties and political expectations, he remains steadfastly protective of Aerin. He regularly defends her when the rest of the court acts with hostility toward her.

Arlbeth is the wise and steady king of Damar. As a monarch, he constantly weighs the good of his kingdom against his personal feelings. He cares deeply for his daughter but struggles to express his affection openly or defend her against the court's prejudices, creating a painful distance between them.

Maur is the legendary Black Dragon, an ancient beast whose size and power completely dwarf the smaller dragons native to modern Damar. He is a terrifying force of destruction who awakens to lay waste to the countryside. His immense presence challenges Aerin to face a truly deadly test of her skills.

Agsded is an evil sorcerer from the North who wields immense magical power. He is intrinsically tied to Aerin's Northern heritage and serves as the dark architect behind the chaos threatening Damar. He seeks to conquer the land and destroy anyone who stands in his way.

Luthe is an immortal healer and magic practitioner who lives in a hidden mountain valley. He serves as a guide and teacher to Aerin, helping her recover from devastating injuries. He instructs her in the ways of magic to prepare her for her ultimate quest to save Damar.

Galanna is the second sol of Damar and a stunningly beautiful royal who craves social dominance. Because Aerin's birth disrupted her position as the center of attention in the household, Galanna dedicates herself to tormenting her younger cousin. She possesses a minor magical ability and uses her influence to isolate Aerin from the rest of the court.

Perlith is the second sola of Damar and Galanna's husband. He is a charismatic but cruel courtier who uses his minor magical abilities to exert subtle power over others and embarrass those he dislikes. He aligns perfectly with his wife's vanity and shares her active disdain for Aerin.

Talat is King Arlbeth's former warhorse. He lives retired in a pasture after a severe leg injury disabled him during a battle. Proud and initially aggressive due to his pain and isolation, he gradually bonds with Aerin. Together they develop a unique riding style that accommodates his physical limitations.

Teka is a loyal house servant and surrogate mother figure to Aerin. She watches over the young sol with fierce devotion, providing practical care, emotional support, and stories about Aerin's maligned mother. She is highly protective and frequently worries about Aerin's unconventional hobbies.

Hornmar is a royal groom who works in the Damarian stables. He provides Aerin with practical advice regarding Talat's physical health and limitations. He is a rare friendly presence among the castle staff who respects Aerin's bond with the animals.

Nyrlol is a chieftain in the West of Damar who falls under demonic Northern influence. He seeks to secede from the Damarian kingdom, forcing King Arlbeth to ride out with his army to confront the insurrection and secure the realm's borders.

Katah is the oldest sol in the royal household of Damar. Like the other members of the royal family, she is caught up in the traditional social structures of the palace and observes the rigid rules of courtly life.
