Haven

Haven, designated MX5-309 by the Tau'ri, is a planet in the Pegasus galaxy that was once home to the Travelers.

History
Haven was the first planet settled by the Travelers in more than 100 years.

Their planet was invaded by the Unknown Aliens, who enslaved the population to build a base and a fleet of Alien fighters on their planet.

Larrin and the Traveler fleet organized to attack the aliens. While waiting for their ships to arrive, they saved the Athosians on New Athos, who were also being attacked by the Aliens, which resulted in the Daedalus finding the Traveler fleet. Together they arrived to Haven. Colonel Caldwell had all of the planet's Travelers beamed aboard, which alerted the Aliens to their presence and started a fight between the two fleets in the planet's orbit.

After the battle, the Travelers considered colonizing a different planet, with one in mind that didn't have a Stargate, and no Wraith or Unknown Aliens.
