a.k.a. Reynard (by Dora, during her madness)
A creature discovered with an insane human man at the edge of the pit into the crypts of Briarstone Asylum. He initially presented as a scared, filthy, and malnourished arctic fox.
After looking into the pit and seeing the thing below the earth, Dora immediately began caring for him like a child and gave it the name “Reynard.”
When Dora cast detect thoughts in Chapter 18, she learned that Reynard had an above average intelligence, a level almost entirely unknown for typical animals.
In Chapter 27, while Thema had control of Dora‘s body, she released the fox, who ran deep into the fog of the North Courtyard of the asylum. Dora later found him wrapped around Brin‘s corpse.
In Chapter 31, Reynard expressed great discomfort with the champagne fox that Ray decided to let follow the party.
In Chapter 34, it was revealed that the fox was actually a middle-aged Kitsune man with black and white striped hair. He was also suffering from mental trauma, but remembered a school, and a person—a spouse or lover—and a book, and then… worms. He came out of his transformed state on 3 Neth and met the party and other chapel survivors at Briarstone, where he had been a patient. Naysa recalled stories of him singing to the other patients.
