The Troigs were a race of bicephalous beings native to the planet Pollillus. Troigs often had different colorations on each head, most often green and red, and each head was supported by a long neck. Their stout bodies were studded with four long arms and short legs. One of their four hands was considered the primary hand, while the others were regarded as off-hands. The hands required that each head work together in order to operate with any level of coordination. Each head, the left known as Saprah and the right as Saprin, was capable of independent thought, and was humanoid in appearance. Troigs with three or more heads were born, although they were extremely rare. They were also revered and celebrated among their people.
