Sebastian, a Komodo dragon Amari, stands as a testament to resilience and fierce determination. At thirty-five years old, his physique is a blend of human and reptilian traits, with jet black hair that is half shaved and pulled up into a shaggy ponytail. His attire reflects his dual nature; he dons grey robes with green fabric draped over them, complemented by tarnished armor. Dark grey wraps and a hood complete his ensemble, hinting at his secretive life. His skin is adorned with green reptilian scales, and dark green tattoos run along his arms, neck, and over one of his bright yellow eyes, symbolizing his heritage and the trials he has endured. Sharp fangs and claws, along with a long lizard-like tail, mark him as a formidable warrior.

Sebastian's life is deeply intertwined with the northern clan, where he was raised and trained as a skilled fighter and assassin. Yet, his heart beats strongest for his young son, Jackson, whose capture by the cruel northern clan leader, Varkas, forces Sebastian into a life of reluctant obedience. Driven by the fear of losing his son to Varkas's brutality, Sebastian embarks on a dangerous mission to assassinate the western leader, Conner. However, upon confronting Conner, Sebastian's plea for help in rescuing Jackson sways the western heroes to his cause.

Together, they infiltrate the castle in the western lands, now under Varkas's control. The mission is fraught with peril, but Sebastian's intimate knowledge of the northern clan's strategies and his fierce determination fuel their success. The heroes manage to overthrow Varkas, freeing not only Sebastian's son but also liberating the Amari lands from tyranny.

Throughout this journey, Sebastian's unique trait of speaking in a low, raspy voice, reminiscent of the hissing of a serpent, adds an eerie yet captivating dimension to his character. His life is a tapestry of conflict, torn between his duties as a clan member and his unyielding love for his son, pushing him to navigate the treacherous waters of betrayal and loyalty.
