Sebastian is a stout, rugged dwarf with a tangled, dark beard and dark brown hair, usually several days from a proper braiding. His skin is weathered and tough, showing scars from countless brawls and battles. His piercing blue eyes are often bloodshot from drinking, but they retain a sharpness that warns others not to underestimate him. He wears patched and battered studded leather armor that bears the marks of years of use, paired with a pair of viciously gleaming adamantine spiked gauntlets that seem to be an extension of his fists.
