Vector Prime was the Yuuzhan Vong term for the path from which they would begin their invasion of the galaxy. It was located in the outer edges of the Dalonbian sector, (Grid location: L-3) near the Helska system. The invasion was needed to start in Vector Prime due to it being the only place known where the Yuuzhan Vong fleet could penetrate the energy field surrounding the galaxy. However, other Yuuzhan Vong suggested it had been chosen due to its proximity to the New Republic/Imperial Remnant border, which made both parties less able to respond.
