These vaguely insectoid creatures (despite having only four limbs), have a long, thin body, roughly 3 or so feet long with a serrated spine, and their color ranges from grey, to black, to steel, to silver, to pale green, always with a shiny and metallic look. While the neck, sides and tail of the Kruthik are bare, the legs, head and back are protected by spiny, jointed plates which eventually grow to protect the full body. In the unprotected parts of a Kruthik’s body, organic lights of a color corresponding to that of the Kruthik’s body glow. The Kruthik has razor sharp teeth, and a pair of mandibles. In addition to its four major legs, the Kruthik also has a much smaller pair of limbs hanging from its chest just a little back from the front two major ones.
Kruthik are known for their voracious appetites, but not much else is known about them. In Eberron, they appear infrequently, and many scholars believe that they dwell somewhere in Khyber in greater numbers. The only thing that is truly known about Kruthik is their avoidance for the smell of their own blood; a Kruthik will not willingly approach an area where other members of it’s race have died in recent months. Due to the foul, vinegar-like stench that Kruthik blood tends to have, most other creatures will avoid the location of Kruthik death, as well.
