In high-efficiency faster-than-light travel, Stargate Technology involves complex construction and lacks flexibility, yet it offers low single-trip costs, suitable for large-scale and frequent fixed travel. The Galactic High Governance Council built an extensive Stargate system throughout the Galaxy, which all high-level civilizations have the right to use, for a fee.
However, a normal Stargate requires setting up at both the origin and the destination to enable two-way travel.
But there are exceptions. In the complex and challenging tech tree of Stargates, there exists a technology that is difficult to master: the one-way Stargate.
