The Conduit is a Vaul structure primarily used to warp-in more advanced technologies.
Terran ingenuity, Zerg hyper-evolution and recent Protoss technological advancement have made it clear that conventional infantry would not last long without heavy support from more powerful machines. Despite Foundries being able to produce legions of basic infantry, the energy requirements to produce more advanced technology would be easily sensed by even the lowest of Terran psychics. This posed a tremendous risk of detection from unwanted factions. So to produce these types of machines, the Vaul had to construct them on bases hidden outside the galaxy.
Like protoss Gateways, the Conduit transforms into a more powerful Void portal to further enhance the mobility of Vaul forces.
