Darien 224

Darrien 224 is a planet located in the Darrien 224 system of the Alpha or Beta Quadrant.

Thousands of years ago, before the teachings of Surak spread across Vulcan, a group of Vulcans established the Last-of-All-Cities colony on the planet's surface. With the oncoming turmoil on Vulcan, the Darrien 224 colony became lost and forgotten. Being left alone, divisions began to form between the Vulcans and at least two rival factions formed in order to gain absolute control of the planet.

In 2254, the USS Cortez (NCC-1834) entered the Darrien 224 system on a survey mission and soon discovered the lost Vulcan colony. After a short while, the crew of the Cortez fell victim to their internal politics and was boarded and taken in battle by one faction. She was later refitted with powerful pre-Reformation Vulcan weapons.

When the Constitution-class starship USS Enterprise (NCC-1701), under the command of Captain Christopher Pike was sent to investigate the disappearance of the Cortez, the Enterprise also became embroiled in the colony's internal strife. She managed to narrowly avoid the Cortez 's fate by repelling another boarding attempt.

This capture having failed, the commandeered Starfleet vessel was used to attack the Enterprise, which was only saved when the Ruler of the Last-of-All-Cities fired a planetary Doomsday Weapon, utterly destroying the Cortez and most of the members of the main opposing faction.

Firing this weapon had a devastating effect on the colony, powered as it was by the planet's core energies, and the Last-of-All-Cities was also destroyed in the planet's upheavals. (EV comic: "Cloak and Dagger").
