Humans have had no contact with the Kr'Thak. What is known to the UEE about the Kr'Thak comes only from the Xi'An. The Xi'An and Kr'Thak have been enemies for seven hundred years and for the UEE to try and make contact with their allies' enemy is not viewed as a bright political move. The Kr'Thak's home system is called Krell and it is located on the other side of the Xi'An Empire thus making it even more difficult to make contact with them. They are a space-faring, nomadic race that own several solar systems, but migrate around them.[citation needed]
