Sebastin Onyx, a Human, served as a protocol intermediary and language interpreter at Jugsmuk Station located on Gamorr. He was a man of diminutive stature, characterized by light-colored hair and a timid demeanor, though he possessed a cheerful and eager disposition. For the majority of the year, Sebastin leveraged his profound linguistic abilities to assist merchants visiting the planet in their interactions with the indigenous Gamorreans. Given the Gamorreans' aversion to droids, a Human translator was a highly valued asset on Gamorr. During the summer and winter seasons, he supplemented his income by crafting poetry for lovelorn male Gamorreans.
