In early 2376 Voyager inadvertently trespassed into underspace corridors under the control of the Turei. The Turei demanded access to Voyagers computers in order to wipe out all information concerning the corridors, which Captain Janeway naturally declined. The Turei vessel responded by firing on Voyager, crippling the ship and forcing it to land on a nearby planet. The Vaadwaur suffered heavily in this battle, but fifty two of their vessels escaped into the underspace corridors. It is more than likely that Voyager has not yet seen the last of this species.
