Omega IV
Type:	Planet
Native Species:	Omega IV natives (The Kohms and the Yangs)

Omega IV was the inhabited fourth planet of a star system. The planet's inhabitants were a humanoid race, divided into two ethnic groups, the Kohms and the Yangs, who had fought a bacteriological war centuries ago. (TOS: "The Omega Glory") The location of Omega IV was depicted on a Federation star chart. It was located near Omega Cygni. (TNG: "Conspiracy")

HistoryEdit

While the planet had different landmasses from Earth, Omega IV shared a history nearly identical to Earth's, up to the 1990s or slightly beyond. Omega IV once had a nation called "The United States" similar to Earth's United States of America, with the same handwritten United States Constitution, the Pledge of Allegiance and Unites States flag identical to that of Earth's.

The stand-off on Omega IV had escalated into open bacteriological warfare. One of the primary weapons of the war was a virus that disrupted the body at the molecular level, separating water molecules from other organic compounds until there was nothing of the body left but dehydrated crystals. The virus was still present on the planet in the 23rd century, though only a brief exposure to the atmosphere at that time was needed to provide a lasting immunity to the virus. The Asiatic Kohms, originally called "Communists", won the war against the Caucasian Yangs originally called "Yankees". As the survivors of the war adapted to the toxic environment, they acquired a naturally long lifespan. They could live to be more than a thousand years old.

The Yangs were driven from their cities, and took to the ways of the native Americans for survival. By the 23rd century, civilization on Omega IV had returned back to the iron-age level. The Yangs, dressed in tribal attire, lived in the hills and mountains surrounding the ruined cities. The cities were inhabited by the Kohms, who dressed similarly to Earth's Mongolians. The Yangs were attempting to take their old cities back from the Kohms.

In 2268, Captain Ronald Tracey of the starship USS Exeter beamed down with a landing party to survey the planet for research purposes. He found the Kohm city and established friendly relations with the Kohms. However, when some of the landing party beamed back to the ship, they carried the virus back with them. Within a short time the entire crew of the Exeter was killed.

Captain Tracey, without a ship or a crew, sided with the Kohm villagers in their conflict with the Yangs. He used his phaser to drive off a Yang attack in violation of the Prime Directive. When the USS Enterprise arrived to investigate, Captain Kirk refused to help Tracey in the battle against the Yangs. He took Tracey away from Omega IV and allowed its people to rediscover their own "history and liberty." (TOS: "The Omega Glory")
