- "Our world is our own."
Velieris was the homeworld of the Nox, and represented one of the oldest continuously-inhabited planets in the Milky Way Galaxy before its destruction. Although it appeared void of intelligent life to the unprivileged observer, the world was teeming with a population that simply chose to render itself and its floating cities invisible to the naked eye. Ignorant of the planet's true masters, the System Lords often hunted rare prey on its surface, but were driven off permanently when SG-1 made first contact with the Nox and forced them to reevaluate their outlook on galactic life. Later serving as an well-protected fortress of the reborn Alliance of Great Races, its kindhearted inhabitants allowed millions of refugees from the war with the Der'kal to take shelter on and below their flying metropoli. The displaced were eventually relocated to other Alliance planets when the Nox lured a massive alien armada into orbit and triggered a supernova within their star, resulting in a supernova that obliterated everything in its path, including Velieris.
