The Vardon-Kosnax War was a war that took place 140 million years BC between the Vardon and the Kosnax. The planet Xeriphas was caught in the crossfire of the war and devastated by radiation. The native Xeraphin, who were poisoned, merged into a gestalt intelligence and travelled in a ship to Earth, which at the time was nearing the end of the Jurassic period. (TV: Time-Flight)
