The planet Marilac had two wormhole exits that led from it; one connected to Xi Ceta, one of the eight satrapy planets in the Cetagandan Empire and the other connected to Zoave Twilight, which was a major Nexus crossroads. Astrographically, its placement in the wormhole Nexus was extremely similar to Vervain's. The Garson Transfer Station and Vassily Station were in or near Marilacan space.
