Abridged History
Until the year 2363, this dimension progressed extremely similarly to that of the canon Star Trek universe. However, after this time, this dimension spiraled in a different direction. Technology advanced at a much slower pace, and discipline began to fall away, as the high ranking officials became corrupt. Before long, hundreds of officers were dying weekly and ships were being lost by the day.

Several high ranking officers took advantage of the situation and formed their own smaller groups within the government. These groups often battled each other for supremacy. The Head Admiral often used his power for corrupt purposes. A few of the higher ranks who knew the extent of the corruption (such as Admiral Ugly, Captain DeSanto, and Commodore Carlos) battled tirelessly to remove this corruption.

That crusade was eventually put on hold when a terrorist organization that called itself Traxia began making attacks on the Federation. The Federation was entirely unprepared. Its officers were untrained and ships out of date. The USS Victory-D, once the prized flagship of the Federation, manned by the finest crew, had become a laughing stock. Before long, Traxia managed to take over several entire planets. The Federation Council declared a state of emergency.

The few competent officers in Starfleet were assigned to ships such as the USS Victory-D, USS Paladin, and the USS Chicago. Those ships were frequently reassigned around the Federation, often preforming the tasks of entire fleets while undermanned and battle-broken. In the matter of a few months, Traxia had become a formidable fighting force.

The Federation continued to lose ground. One of the Federation's greatest losses came when Admiral Ugly defected to Traxia's side. Traxia was, at its roots, an organization against corruption in the Federation, the same agenda Ugly had. Ugly helped Traxia develop technology far superior to the antiquated ships being used by the Federation. Several other competent officers such as Vulcanian, Estricta, and more also defected to Traxia's side.

Traxia's fleet grew to an alarming size. In a last ditch attempt to stop them, the entire Federation fleet massed around Earth. Klingons and Romulans sent help, recognizing that Traxia was a bigger threat to them than the Federation. Ugly led the Traxian fleet, while Admiral Bunny led the Federation fleet. Admiral FuwwyFox was the second in command of the fleet. One of the few competent admirals remaining, he fought valiantly until the end.

The Federation was undoubtedly going to lose, so in a last ditch effort to stop Traxia, Bunny detonated a device that caused a rift in spacetime, destroying Sector 001 and several surrounding sectors. Spacetime across the dimension was so damaged that most attempts to reach this dimension now fail entirely. Since then, no news from dimension 001 has been received.
