         ● [1]
         The surviving remnant of the Caeliar city Mantilis arrives in the Delta Quadrant, landing on an inhospitable region of an inhabited planet. The handful of Caeliar and MACO begin a grueling fight for survival. [1]
 
         ● [1]
         With starvation and predators gradually claiming the survivors of Mantillis, the last remaining Caeliar creates a nanotechnology system to allow it to survive, assimilating a MACO and using the other humans as a food source. The resulting cybernetic creatures are able to hibernate until discovered by the natives of the planet, whom they assimilate to form a collective intelligence. The result is the creation of the Borg species. [1]
