The jaws work from side to side and have several small extensions that grab and manipulate food while it is being eaten. The four forward limbs each have a hand with three fingers and an opposable thumb.Ī thri-kreen's head has two large eyes, two antennae, and a small-but-powerful jaw. Its hind legs are the most powerful, used for walking, running, and leaping. The individual thri-kreen is a six-limbed creature with a tough, sandy-yellow exoskeleton. Their survivability in the wilderness, combined with their cunning and intellect, have made the mantis warriors (as they are known to some races) the undisputed masters across large tracts of the Athasian wastes. Hulking insect-men standing as tall as 7 feet at the shoulder, the thri-kreen are the least 'human' of the player character races.
