A planet that fought a centuries-long war with Vendikar by computer, sending real citizens to die in disintegration chambers, until Kirk ended it in 2267.
Eminiar VII is a planet whose government had been at war with the neighbouring world of Vendikar for about five hundred years. Rather than fight with weapons, the two sides used computers to simulate attacks. Each simulated strike produced a list of casualties, and those citizens were required to report to disintegration chambers so that the war could go on without destroying their civilisation.
In 2267 the USS Enterprise arrived carrying Ambassador Robert Fox to open diplomatic relations. The Eminians declared the ship a casualty of a simulated attack and demanded that its crew be killed. James T. Kirk refused and destroyed the war computers, leaving both sides facing the real horrors of war. Faced with that choice, the Eminians agreed to seek peace with Vendikar.
Eminiar VII is the setting of A Taste of Armageddon, one of the Original Series' clearest stories about the cost of war. It shows Kirk's willingness to break rules to protect life and his belief that people must face the truth to change.
