Tria

The Tria was an Aurora-class warship during the Atlanteans war with the Wraith. During a battle, the ship was damaged, and recieved word that the Atlanteans had already left Atlantis via the Stargate for Earth. Unable to rejoin them by Stargate, the Tria made the long cross between the Milky Way and the Pegasus galaxies. Halfway through the trip, the hyperdrives failed irreparably. Unable to turn back, the crew modified their sublight drive to go 0.999 of lightspeed, but due to relativity, they would only experience a few years, which could be further lessened through stasis. When the Tau'ri were testing a new Gate bridge they developed, the crew of the Daedalus made contact with the vessel, and transported its crew back to Atlantis. The fate of the Tria is unknown. Although it is possible that the Replicators had broken down the Tria and used it as nanite raw material to replicate furthur more.
