Janus

"The more someone told him not to do something, the more he had to do it."

- Elizabeth Weir

Janus was a Lantean who lived on Atlantis in the Pegasus Galaxy 10,000 years ago. He built a timeship out of a Gateship which was used by an alternate timeline version of Dr. Elizabeth Weir in her attempted escape from the flooding of the entire city of Atlantis caused by the expedition team's arrival. Janus' timeship crashed 10,000 years ago in the Pegasus Galaxy.

While Major Sheppard and Dr. Zelenka were killed, he was able to save Weir, and became her advocate when she met with the Atlantean Council. While he argued and defended Weir on hr behalf that she should be allowed to return to her own timeline in order to prevent the Atlantis Expedition from falling into the same tragedy again, High Councillor Moros and Melia refused, with Moros angrily condemning his experiments, and ordered the city to be evacuated as well as Janus' timeship destroyed.



Attempting to change the fate of the future Atlantis Expedition from walking into the same disaster as she herself faced, Weir pleaded to Janus to help her find a solution that would save the expedition from walking into the same disaster she faced with herself. Janus agreed to help her and after doing some calculations, he concluded that rotating the Zero Point Modules sequentially, manually, would save the city.

However, in order to maintain the city's power to hold the shields around the city, the three Zero Point Modules had to be manually turned sequentially every 3,000 or so years. Weir decided to stay behind in the city to perform the task. Janus programed a stasis pod to reawaken Weir every 3,000 years or so, so that she could manually turn the ZPM's. He also programmed a failsafe-mechanism into the city should power and shields drop.

As Weir decided to stay behind, Janus himself decided to escape with the rest of the Atlanteans to Earth, hoping that his efforts to save Atlantis with Weir's help for the future Atlantis Expedition would succeed.



''It is possible that he created a new timeship in the Milky Way Galaxy and that ship was the one discovered by SG-1 on Harry Maybourne's planet.
