Vaylen is a Twi'lek who stands approximately 1.85 meters with a solid, if slender, frame that speaks to a life of physical activity and minimal available nutrition. His skin is a deep tan color, toned by hours spent underneath sunlight. He has amber colored eyes, which seem deceptively calm, with the occasional spark hinting at a deep burning flame. From the base to the tip of his lekku, Vaylen has tattoos, signifying his membership and devotion of the Kreysh'Ullan Order. Vaylen typically dresses in practical clothing, favoring mechanic coveralls or his flight suit to more formal garb.
