Telquorkhans stand on two legs. Their teeth sit on the outside of their mouths. They have dark green serrated skin, a helmet-shaped head and a short tail. They do not have eyes.
These are the most deadly. They infect their victims brain with a worm. Even Citizens are not safe from their sting.
They communicate telepathically.
They may be blind, but they can quickly sneak up on their victims, without being heard until they make their eerie clicking sound.
