2007

• SG-1 sends the Sangraal to the Alteran Home Galaxy, killing the Ori.

• The Atlantis expedition discovered the underwater drilling platform that the Ancients built on Lantia. While surveying the facility, the team encountered and killed the Wraith Queen who led the siege on Atlantis. She had survived the 10,000 years since that time by hibernating and feeding off of her crew until only she remained.

• The Asgard commit mass suicide, leaving their technology and history to the Tau'ri.

• SG-1 flies the Odyssey through the Supergate to the Alteran Home Galaxy to find the Ark of Truth and uses it to spread the truth of the Ori to the people of both the Alteran and Milky Way galaxies

• The Ori War ends

• The IOA sent the newest 304 to Pegasus, the Apollo, with the Horizon Weapons Platform to destroy the warships that the Asurans were building on their homeworld. In retaliation, the Asurans send an Asuran Stargate satellite weapon to Lantea, which fires a high energy beam on Atlantis. To escape this beam, the expedition evacuate Lantea by launching Atlantis into space, by using the ZPM and the emergy from the underwater drilling platform.

• While Atlantis is traveling through space to their new homeworld (M35-117), the city-ship drops out of hyperspace due to damage substained by the Asuran Stargate satellite weapon. While repairing Atlantis however, the ZPM power levels drop below the minimum level to jump into hyperspace again and continue their journey to M35-117. AR-1 and Weir therefore decide to use an experimental hyperdrive generator on a puddle jumper to travel to Asuras and steal a ZPM from the Asurans. During the mission however, Weir was discovered and captured by the Asurans. AR-1, without Weir, return to Atlantis and use the captured ZPM to power the city-ship's decent onto a new homeworld (M35-117).

ATL: "Lifeline"

• The expedition infiltrates Asuras to steal a ZPM and activated the Asuran base code to attack the Wraith, thus starting the Asuran-Wraith war, but with the expense of Dr. Weir.

• Newly-promoted Colonel Samantha Carter, formerly of SG-1, is appointed as the new commander of the Atlantis Expedition.

• McKay is captured by the Wraith, in-order to shut down the Asurans' attack code. The remaining members of AR-1 rescue McKay however, before he was able to make any changes to the code.

• John Sheppard is captured by a group of ship-faring people known as the Travelers, who want to use his Ancient gene to reactivate a dormant Aurora class warship. The Travelers wanted to use the Aurora class warship to help resolve the population problems faced with the race's limited number of ships.

ATL: "Travelers"

• Teyla's people, the Athosians got kidnapped by the Wraith Michael

• The Atlantis Expedition met Davos of the Vedeenans, who could see future events in remarkably detailed visions, which he was also able to share telepathically

• The Asurans eventually attacked human worlds as a new strategy to defeat the Wraith.
