Description
Star-gates are ring-shaped machines that directly connect two locations in space. All star-gates are constructed in pairs that connect to one another. They are huge and very expensive to create. The two halves are built together, and then, after the gate has been activated, the two pieces are separated, one going to either location that is to be connected. Once activated, there is no way known to shut down a star-gate. The construction of star-gates requires large amounts of exotic, and hard to obtain substances. The absolute minimum size a star-gate can be is about 500 Meters in diameter. If one half of a star-gate is destroyed, both halves will explode with a colossal amount of energy.
History
In the Empire of 1,000,000 Suns, the star-gate was invented well before the 1,000 Years War. The legendary engineer, Kroah Dashan, oversaw the creation of a dense network of star-gates that protected imperial shipping routes from piracy, but also helped keep the Empire provincial.
Within the E1MS, and in a few other places, there are some ancient, dormant star-gates, known as the Zanathian Gates. They are rumored to have been built by a civilization even older than the E1MS.
In human space, Star-gates were invented midway through Era-1, but the Planetary League only ever built a handful connecting a few major systems and regional capitols. The Holy Empire of Man built a few more during Era-2. Era-3 saw a dramatic rise in the use of star-gates, after the Galactic Republic discovered a more economical means of production.
