World One

was one of the many worlds of Multiworld.
World One recreated both a Jurassic period of Earth and a Arabic environment.
Variations of the Sontarans got stranded on World One as well, and they acted as the local population. One of the Sontaran variation was called Caliph Sul'taran. (COMIC: When Worlds Collide)
