Elatsoe, often called Ellie, is a 17-year-old Lipan Apache girl living in an alternate America where magic is real. She possesses a hereditary family gift that allows her to raise the ghosts of animals from the underworld. Passionate about paleontology and paranormal investigation, she relies on her quick thinking to investigate the suspicious death of her older cousin in South Texas.

Trevor is Ellie's beloved older cousin who works as an elementary school teacher in the Rio Grande Valley. He is a humble, dedicated family man who recently welcomed an infant son. When he dies in a mysterious car accident, his sudden passing sets off Ellie's investigation into the town of Willowbee.

Jay is Ellie's lifelong best friend and frequent partner in her paranormal investigations. As a descendant of the fairy king Oberon, he possesses the ability to generate light. He is a high school cheerleader with an optimistic spirit, eagerly offering his research skills to help Ellie uncover the truth about her cousin's death.

Dr. Allerton is a highly respected, wealthy physician living in the insular town of Willowbee. He maintains a pristine public reputation through extravagant charity work and tight connections with local law enforcement. Underneath his charming exterior, he aggressively protects the dark secrets behind his unusually high medical success rate.

Kirby is an English springer spaniel and Ellie's constant ghost companion. Ellie brought him back from the underworld after his death using her family's ghost-training gift. He serves as an invisible protector who can sense when Ellie's loved ones are in pain or danger.

Vivian is Ellie's mother and a knowledgeable Lipan Apache woman who deeply understands the traditions of ghost-training. She constantly guides Ellie to respect the strict boundaries between the living and the dead. While protective of her daughter, she recognizes Ellie's growing power and respects her drive to uncover the truth.

Ellie's father works as a veterinarian and accompanies his daughter on the long road trip to South Texas. He supports Ellie's gifts but remains grounded in the practical dangers of the world, reminding her to stay safe while searching for answers.

Lenore is Trevor's grieving widow and a former teacher. Previously meticulous about her appearance and strictly opposed to ghost-raising, the trauma of losing her husband pushes her to abandon her old beliefs. She becomes desperate to find a way to interact with Trevor's spirit again.

Six-Great-Grandmother Elatsoe is Ellie's famous ancestor and namesake. She was a fearless Lipan Apache monster hunter and gifted ghost trainer who defended her people from colonial violence and supernatural threats. Her legacy casts a long shadow over Ellie's coming-of-age journey.

Ronnie is Jay's assertive sister who is recently engaged to her vampire boyfriend, Al. She is deeply loyal to her social circle and quick to mobilize her extensive friend group to provide backup when Ellie faces danger.

Al is Ronnie's fiancée, a young man living with the vampire curse. Despite initial skepticism from Jay's family regarding his condition, Al actively proves his worth by throwing himself into Ellie's dangerous investigation.

Aunt Bell is Jay's aunt, possessing strong psychic gifts and the ability to travel through fairy rings. She helps Ellie and Jay by reading the residual spiritual energy at the site of Trevor's supposed car crash.

Brett is Dr. Allerton's young son and a former student of Trevor Reyes. He deeply idolizes his father and proudly writes reports defending the colonial actions of his ancestor, Nathaniel Grace.

Nathaniel Grace is a colonial-era ancestor of the Allerton family and the credited founder of Willowbee. Historical records show he built his power and reputation by causing harm to Indigenous populations, setting a dark precedent for his descendants.

Baby Gregory is Trevor and Lenore's infant son. Like his father and cousin, he possesses the Lipan Apache gift to connect with the dead, though he is too young to control or understand it.

Dan is a respected Lipan Apache elder who provides spiritual guidance to Ellie and her family. He sternly warns Ellie against blurring the lines between the living and the dead, emphasizing the spiritual burden of dwelling on death.

Glorian is an ancient Lipan Apache vampire who works as a guard at Dr. Allerton's mansion. He uses his shared heritage to resist Ellie's traditional banishment spells during a confrontation.
