Vega

The star system of Vega is the original home of the Citadel and was the primary location for the Omega Men series. Vega is also home to the Psions, who negotiated far in the past with the Guardians of Oa to interdict any and all Green Lantern activity in the Vega star system. Vega is also of critical importance to the activites of the Spider Guild and represents a major Guild nest.
