Thri-Kreen
From The unofficial Dark Sun wiki
Thri-Kreen: Also called Mantis Warriors, they are tall two legged praying mantis's with four arms, humanoid hands and thick carapaces. They live in hunting packs and use special racial weapons to hunt. They live in a Alpha society and will commonly challenge for their position in a pack. They never need sleep and find it confusing when other races request it. They also need less water and food than other races. They don't generally like to eat sentient races but will make an exception if their is an elf available as they have a taste for elf.
The actual name of the race is "Kreen", meaning "The Mantis People"; Thri-Kreen are the nomadic Kreen from the region of Tyr, while "Tohr-Kreen" ("Settled People") is the preferred name for Kreen who live in towns or other fixed places.
They are an extremely short lived race, never living past 25. They grow up quickly, bolstered by ancestral memories that cover Kreen language and proficiency with racial weapons. They make good use of their time, considering how strong they are by adulthood, and never waste time sleeping.
Their most recognizable weapon is the Chatkcha, a throwing weapon with three blades. They also use Gythka, double bladed staves meant to be used in pairs by the 4 handed.
