Finley is a 23-year-old shifter living in a cursed village where residents are trapped in their human forms. Living in poverty, she risks her life to harvest everlass plants from the dangerous forest. She serves as the primary protector and provider for her family, utilizing her knowledge of plants to brew an elixir that slows the curse's illness. She openly defies the restrictive gender expectations of her community, preferring to hunt and wear trousers rather than conform to traditional feminine roles like needlepoint. Her frustration with the village men stems from their refusal to value her for anything other than her physical beauty.

Nyfain is a cursed noble and the only shifter in the land who retains his ability to transform into an animal, though his first shift sheared off his dragon wings. Bound to a dilapidated castle overrun by incubi and other demons, he acts as the fearsome guardian of the Forbidden Wood. He carries an immense burden of guilt over his people's fate and the ruinous deal his father struck sixteen years ago. Nyfain patrols the borders constantly, using a brooding and surly demeanor to push others away and avoid confronting his emotional trauma.

The Demon King is the powerful entity who cursed the land and stripped the shifters of their abilities. He leaves his incubi and lesser demons to occupy the castle while he wages war elsewhere. He maintains an iron grip over the frozen inhabitants through a magical gag spell that suffocates anyone who tries to reveal his secrets. He weaponizes the desires and sexual energies of the castle's prisoners to feed his own demonic forces.

Hannon is Finley’s older brother who remains at home to care for their ailing father and younger siblings. Unlike the other men in his village, he thrives as a domestic caretaker and strongly believes in finding a true shifter mate. He provides a safe harbor for his sister, patching her wounds after her dangerous excursions. He openly discusses his emotions and encourages Finley to pursue a romantic relationship that respects her independence.

Hadriel is the castle butler, originally from a neighboring kingdom ruled by a wolf shifter. The curse froze his physical age at 26, trapping him in the castle for sixteen years. He despises his situation but regularly participates in the castle's demonic incubus parties out of sheer boredom and a lack of willpower to resist. To survive, Hadriel deliberately hides his talents and rewards his own mediocrity, knowing that the demons execute anyone who displays exceptional strength or ambition.

Leala is Finley’s appointed lady's maid within the cursed castle. She actively embraces the environment the demons have established, willingly participating in their esoteric sexual games in exchange for survival and social privileges within the castle. Rather than succumbing to the self-loathing that plagues other servants, she maintains her agency by finding personal enjoyment in the dark atmosphere. She assists Finley with daily dressing and meals while sharing gossip about the castle's frozen inhabitants.

Jedrek is an arrogant, wealthy man living in Finley's village who aggressively pursues her. He views himself and Finley as the most attractive people in the community and believes they are destined to mate. He completely disregards Finley's autonomy, viewing her solely as a beautiful prize to enhance his own social status. He refuses to accept her clear rejections, demonstrating the entitled attitude prevalent among the village men.

The Queen is Nyfain's deceased mother. Before the curse fully took hold, she bonded with her son by tending to a private garden and sharing her knowledge of the everlass plant. Her former sanctuary now houses a dying rosebush that serves as a painful reminder of her absence. She allegedly died of a broken heart, unable to survive the toxic environment created by her husband's choices.

The King is Nyfain's deceased father and the former ruler of the land. Driven by a desire for power, he struck a disastrous deal with the Demon King sixteen years ago that cursed the entire kingdom. He strictly enforced traditional gender roles, mocking his son's interest in gardening and demanding brutal dominance. His selfish decisions directly caused the ongoing suffering of both the villagers and the castle inhabitants.
