Tarsus IV (Columbia)
In 2247, a fungus devastated the crops and food supplies on Tarsus IV. Governor Kodos declared martial law, and assumed emergency powers. A follower of eugenics, Kodos decreed that those he deemed not vital to the colony's survival were to be executed, in order to provide enough supplies for the remaining colonists to survive. Four thousand colonists were put to death, only for relief shipments to arrive soon thereafter. Kodos was believed to have died, when a charred corpse was discovered at his last known location. Nine eyewitnesses to the massacre survived, including Kevin Riley, Thomas Leighton, and James Kirk. At virtually the same time, Anton Karidian appeared, though no records of him existed prior to this date.
