This technologically superior alien empire has so far-proved little threat — as long as humans stay on their side of the border. The few times Vau ambassadors have parleyed with humans, trouble has resulted, although in forms hard to trace back to the Vau. For instance, the Vau “gifted” humanity with the jumpcoordinates to reach a previously lost world called Pandemonium. This world in turn revealed coordinates to another lost world called Iver. A cold war for the spoils of these new worlds began; the Vau’s present has proven most troublesome.
If the Vau were to expand into Human Space, no one is sure if they could be halted, for their tech is impressive. Human’s stole their own knowledge about energy shields and blasters from early Vau encounters. It is theorized that the Vau know far more about these fields than has been revealed.
