|This article is about the class of starship. You may be looking for the abandoned city on Kharak built from the wreckage of a starship of this class.|
Khar-Toba-class Transports were ancient prison vessels used to ferry large numbers of POWs to other locations. They comprised the convoy that took the Hiigarans to the Outer Rim during their Exile. The convoy ventured through space for generations with no escorts and virtually no contact with the rest of the galaxy. After many generations, the Hiigaran Exiles came to forget their origins, thus reducing their species to myth and legend. The journey through space was hazardous, with many Khar-Toba-class Transports malfunctioning due to their extremely flawed technology, leading to the untimely deaths of many Exiles.
During the voyage, several Khar-Tobas broke off from the convoy to other worlds. One notable Khar-Toba was the one that fled to the safety of the Great Nebula, where they were reborn as the Kadeshi, who made the nebula their home and terrorized anyone who dared to enter it. This Khar-Toba's remains still exist in the nebula undisturbed.
After a long journey, the convoy finally found a habitable planet - Kharak - and landed on it. One of the ships landed in the desert and became the heart of the city known as Khar-Toba. Thus, the Hiigarans were reborn as the Kushan.
It is interesting to note that the only ship of the convoy discovered on Kharak is the Khar-Toba herself. This implies that the others either never made it to the planet or did not land. They might have burned up on reentry. Of course, its more likely that the writers or editors made a mistake.
