The Kr'thak are a spacefaring civilization indigenous to an unknown area of space. Little is known about them, other than their involvement in a period of turmoil in Xi'an history called the Spirit Wars. The Xi'an have strict laws in place preventing the populace from interacting with the Kr'thak and have refused to fulfill information requests from Human. While some Human explorers have made attempts to locate jump points into Kr'thak territory, none have so far been found. In 2943, the UEE Senate discussed establishing contact with the Kr'thak, but ultimately decided against potentially jeopardizing diplomatic relations with the Xi'an.
