The state governing Eminiar VII, led by a High Council under Anan 7, which fought a five-century war with Vendikar by computer and sent its calculated casualties to disintegration chambers.
The Eminian Union is the government of Eminiar VII, the principal planet of star cluster NGC 321. For five hundred years it has been at war with its former colony Vendikar, a war conducted entirely as a computer simulation. Citizens listed as dead in an attack report within a day to be disintegrated, which spares both civilisations physical ruin.
In A Taste of Armageddon, the Enterprise arrives carrying Ambassador Robert Fox despite a warning to stay away. First Councilman Anan 7 informs Kirk that his ship has been declared destroyed and that the crew must die. Mea 3, one of the designated casualties, acts as the landing party's guide.
Kirk destroys the war computers, leaving the Union to choose between real bombardment and peace. Anan 7 accepts Fox's offer to mediate talks with Vendikar.
