The Thlanax Star System is a planetary system within an unspecified stellar system located in the outer arms of the Milky Way Galaxy. It consists of 1 star, 4 planets, and a solitary moon. Two planets 'naturally' possess life, although with Dosganna having been hit by a process of panspermia, and with Rhaonii having been a former extrasolar colony to an advanced sapient civilization, it is possible that all of the system's life originated from other locations.
