Synuefe EU-Q C21-10 System, is an obvious choice. But to scan a Guardian Beacon, Synefe EU-Q C21-15 should be a destination. But "Bridging the Gap" should lead to a new expansion that centers on something other than the ships. I don't believe Guardian Technology was used to modify or create vessels to traverse space. Probably something more important like aiding and assisting in evolving, with the help of genetic engineering.
