Dameon was born on the 5th of Terra in the sick bay on the shores of Eryndor. His mother was infamous pirate captain, Captain Veilwake, and his father was rumoured to be a rival pirate captain. Because she concealed her pregnancy and wanted Dameon to be safe, his life was entrusted to Veilwake's brother Talren and her second mate Kestrel.
 
Kestrel and Talren brought Dameon to Hariel's Rest in the Abyssal Plane, where he remained until adulthood. There he was taught how to survive in the chaotic plane. Talren told Dameon tales of his mother while Kestrel trained him for survival and combat. It wasn't easy and to this day, he can't sleep without a source of light nearby.
 
After gaining independence, Dameon, Kestrel, and Talren traveled to the Azure Citadel in Eryndor, where the trio became part of the official Free Flags crew. However, when Dameon learned that his mother was captured during a naval skirmish and brought to Varanthia, he decided to join the Onyx Circle, hoping that the connections and information he establishes will lead to a reunion with her. Talren gave Veilwake's compass to Dameon as a parting gift. Dameon isn't sure what he wants once he meets his mother again, and doubts that she will even recognize him due to their disconnect and how he's aged from living in the Abyssal Plane, but he still longs to see her and ensure her safety.
 
Dameon's induction into the Onyx Circle was traumatic. He was assigned to kill one of the following: a member of the Free Flags, an unknown woman, or a man that was named a good husband. Choosing to kill the husband, the Onyx Circle also ordered an assassination on Kestrel, a symbol of the end of Dameon's life with the Free Flags and the culmination of his banishment from them.
 
The loss of Kestrel was devastating and led to Dameon becoming jaded at the idea of affection towards anyone from then on, refusing to get close to people in a deep and meaningful way. All of his situationships since then are shallow and superficial, only seeking the thrill of a hook up or conquest. He focuses on work and becoming more efficient at it.
 
The survivor, the unknown women, named Irrine, was a fellow recruit of the Onyx Circle, and eventually became Dameon's shadow. He feels burdened by her and her presence often stirs feelings of shame and grief that he tries desperately to tamp down. She's grateful to him for sparing her and has made many attempts at camaraderie, but Dameon keeps her at arms length. She's ultimately a terrible Onyx Knight, which leads to frustration as Dameon needs her to succeed.
 
Despite his tumultuous past, Dameon can be very playful and humorous in his interactions with others. He cares about his appearance and makes sure to be well-groomed, sometimes coming across as vain. He conceals his self-doubts with overconfidence and arrogance. Unless on a job, he's very flirty with women. While a womanizer as a way to cope with his trauma and mommy issues, he puts emphasis on consent. At times he may pursue a woman as a conquest, but he rarely sleeps with them more than once, leaving multiple one-night stands and broken hearts in his wake.
