A millennium ago, the Vaadwaur used their advanced technology to map a network of subspace corridors, which allowed them to travel instantly to distant regions of space. They used their technology and the subspace corridors to conquer a vast empire of worlds across the Delta Quadrant.
Some of the conquered races banded together and attacked the Vaadwaur home world, wiping out most of the race. By Stardate 53167.9, only a handful of Vaadwaur survive, and the subspace corridor network is controlled by the Turei.
The Vaadwaur had many encounters with the Borg 900 years ago.
The Vaadwaur also encountered the Talax-Ilzay -- now called Talaxians -- long ago.
