Eurydic Expanse

The Eurydic Expanse is a region of uncharted space on the extremities of Federation territory. The Expanse is irregular in shape, and is surrounded entirely by the Necro Barrier.

The first ship to enter the Expanse was the USS Ethos. The USS Endeavour followed soon thereafter. Both vessels played a pivotal role in the final defeat of Khan Noonien Singh.

Necro Barrier
The Eurydic Expanse is surrounded by a ring of densely-packed asteroids known as the Necro Barrier. The barrier's thickness is roughly 23,000 kilometers, but varies by several hundred either way.

The USS Ethos successfully traversed the Necro Barrier in 32 hours, travelling at an average velocity of 200 meters per second (720 kph/447 mph). The Ethos was forced to use its phaser arrays as a method of clearing debris from their path. As noted in Captain Doyle's log:"'[the Ethos 's] phasers have been fired more times in the last twelve hours than they have in the entire time the Ethos has been in service.'"

Interior
The Eurydic Expanse contains numerous planetary systems, and appears much like the rest of the galaxy. This observation indicates that the Necro Barrier may have been constructed by an intelligent warp-capable species that has since gone extinct.

Some of the planetary systems present in the Eurydic Expanse are the Kelvis System, the Kuscharz System, the Crynax System, the Morak System, the Essex System, the Latvius System, the Macgyvis System, and the Lekaran System.

Inhabitants
The Eurydic Expanse is inhabited by at least one known intelligent warp-capable species: Drakovians.

Drakovians
(Main Article: Drakovians)

The Drakovians are an enigmatic race that appear to dominate a portion of the Expanse nearest the Federation. The Drakovians are potentially xenophobic, but certainly hostile. All Drakovians that have been encountered were equipped with an environmental armor suit. It is logical to assume that all Drakovians soldiers maintain this practice.

The Drakovian planet of origin is unknown, although it can be inferred that the planet is within the Eurydic Expanse. Drakovian technology is considerably more advanced that the Federation's, with their superiority including the ability to contain (and possibly generate) dark matter and the ability to create artificial wormholes. Drakovian vessels, however, appear unable to exceed Warp 10.
