The Bolians (Second Human Empire: Hamo Vuyyi'uui Bui'kkil) were a humanoid species who were native to the Allied planet Bolarus IX. Bolians were distinctively known for a bifurcating (cartilaginous) ridge running vertically along the center of the head and face, and partway down the chest. Skin color ranged from light green-blue to blue-gray to vivid blue and was occasionally accented with dark blue bands on the head.
