Thri-kreen

The thri-kreen were an insectoid humanoid race that primarily lived in the Shaar.

Physical description
They had six limbs: two for walking and four to use as arms. Their heads had compound eyes and antennae. They secrete a paralyzing poison from their mouths, and have claws.

Combat
The thri-kreen primarily fought with two types of weapons: the gythka, a two-headed spear, and the chatkcha, a crystalline throwing wedge.

Society
The thri-kreen were a race of nomads and hunters, and controlled the land just north of the Toadsquat Mountains. They were alien in their thinking, regarded by their neighbors as savage and brutal, and are not liked by humans and their ilk. The thri-kreen traded with some loxo tribes and would fight anyone they viewed as intruders upon their territory without fear of death.
