P3X-289

A planet that is completely toxic but with a small haven not far from the Stargate that is toxic free. Survivors from the planet lives there, although in very small numbers. They acces what they call the Link for getting all the information they need and have so survived for 400 years, because of this dome's energy barrier that's also controlled by the Link.

The planet is now abandoned since the dome didn't have enough energy to sustain the people in the controlled environment. ([SG1: "Revisions")
