The Red Ocean. The distant collection of stars orbited the Milky Way Galaxy at a distance of approximately 350,000 light-years.
Crossing this distance was unimaginable to many people, but the Big Two managed to pull it off. Not only that, the MTA and CFA pooled their resources together to construct a pair of massive greater beyonder gates!
Utilizing a huge amount of phasewater as well as a dizzying array of high technology, these enormous gates formed a space tunnel between two extremely distant points of space that could temporarily connect them together!
The more astute scientists figured out that beyonder gate technology was likely derived from the more modest and limited portal jumping technology that the warships of the Big Two utilized on a regular basis.
