Sebastian, a brooding figure cloaked in the shadows of his own existence, navigates the night with a quiet intensity. His pale skin, a testament to his eternal night, contrasts sharply with his jet-black hair, which he keeps long and often tied back in a loose ponytail. His eyes, a piercing shade of crimson, reflect a depth of sorrow and a burning desire for retribution. At a glance, one might mistake him for a man in his late twenties, yet his true age, lost to the centuries, adds layers of mystery to his already enigmatic persona. Sebastian's attire, a blend of vintage and modern, speaks to his dual life; he dons a leather jacket over a crisp, white shirt, paired with dark jeans and boots that have seen many a midnight stroll. His unique quirk is his obsession with vinyl records, a passion that led him to work at a record store by day, where he finds solace in the melodies of the past.

Sebastian's life took a dark turn when he was turned into a vampire by the one he now seeks to avenge. This betrayal fuels his every action, driving him to uncover the whereabouts of his maker. His pet fish, Captain, a silent companion in his lonely existence, swims in a tank atop a stack of old records, a symbol of the life he clings to amidst the chaos of his vengeance. The conflict in Sebastian's life stems from his struggle to maintain his humanity while succumbing to the primal urges of his vampiric nature. His journey is one of solitude, marked by the haunting tunes of the records he cherishes, as he seeks to confront his past and reclaim his future.

In his quest, Sebastian employs his intelligence and cunning, using his position at the record store to gather information and resources. His plan works because of his meticulous nature and his ability to blend into the shadows, unnoticed by those who might thwart his mission. Yet, as he draws closer to his goal, the line between his humanity and his vampiric nature blurs, leading to a climactic confrontation that tests the very essence of his being. In the end, Sebastian's journey is one of self-discovery, as he grapples with the consequences of his actions and the realization that true revenge may cost him more than he bargained for.
