History and specifics[edit | edit source]
10,000 years ago, the native Dhauti civilization used genetic engineering to create the Xhosa species as hosts for identity transference, but their creations slaughtered them. An artificial intelligence program in the Monitor's sanctum maintained an electromagnetic dampening field around the planet, which also served as a planetary defense system.
In 2270, the Monitor program was still operational. It activated the defense screen when the shuttlecraft Armstrong attempted to visit the surface, disrupting Vehtora IV's atmosphere. This caused the shuttle to crash and left its crew nearly defenseless against the Xhosa. Spock visited the sanctum and shut down its remaining systems to free the landing party, but also to allow the Xhosa a chance to evolve beyond their barbarous nature.
