Arthie Casimir is the dynamic protagonist and one of three primary narrators. Arthie is seemingly in her twenties and is from the fictional country of Ceylan (an analogue of Sri Lanka, given that Ceylon was the colonized name of that country). Arthie is ruthless, calculating, and protective of those she loves, and she holds a particular fondness for her adoptive brother, Jin Casimir. As a child, Arthie witnessed Ettenia’s brutal colonization of her homeland but survived the violence and an illness when she was transformed into a half-vampire. In her struggle to survive, she then killed multiple people, both Ceylan survivors and Ettenian servants. Arthie is simultaneously motivated by revenge and haunted by her history of violence, and this contradiction allows the narrative to explore her character and motivations in greater depth.

Now, Arthie manages Spindrift, and the establishment is her tether to life and humanity, allowing her to interact confidently and safely with a world that hates her for all aspects of her identity. Arthie’s growth in the narrative is directly tied to Spindrift, which in many ways serves as her mask. She also uses other details, such as her purple hair, to distract others from her race.
