Hulking insect-men standing as tall as 7 feet at the shoulder, tohr-kreen & thri-kreen are the least "human" of the player character races. 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.

The To'ksa of the North are aggressive and tend to be more primitive than other kreen; most are nomads, ranging sandy wastes, scrub plains, and stony barrens. Some northern To'ksa clutches live in settlements, particularly among the tolerant Jeral, though some small clutches are found in the nation of J'ez; To'ksa are are very rare in J'hol. Northern To'ksa are barbaric hunters, and are often found in the arenas. To'ksa tend to be chaotic, and are often fighters and gladiators, seldom priests and chakak, and almost never druids. To'ksa are considered the scum of the northern kreen; they are often subjects for the experiments of the Zik'chil.
