Sebastian is uncanny; his skin is lithe and tanned nicely, and his features symmetrical with refined features throughout as if he had but a small pint of elven blood in him.

He stands tall, built strong but not bulky, rather appearing athletically and nimble. Commonly dressed in a standardized uniform, with white and gray hues, he stands out as belonging to the guards; but often is seen without his helmet, along full view of his dark brown eyes and shoulderlong, slightly curled brown hair.
He is quick to a smile, and exudes an air of confidence - resting in himself and the notion that he is to some fairly attractive.
He wears a polished sword by his side, and remains attentive, but prefers to talk rather than draw it.
