McKay finished the last diagnostic on the Odyssey's Alternate Reality Drive, just in time to see Colonel Carter enter engineering.  “Ah, Sam.” he said, handing his tablet to a nearby lieutenant.  “The drive checks out.  The subspace capacitor can be rerouted to the main grid once you're on the other side, though you'll only get about half the power of a Zed PM out of it, a compromise for being able to reroute its output.”

“Thanks, McCay.” she said.  “You'd better get to the rings, though.  We'll be sending the last of the repair personnel back to Groom Lake in a few minutes, then leaving for the other universe.”

“Yeah,” he said, turning to go, then turning back around.  “Just remember that you can reroute the SC and come back at any time.”

“You've already told me that, Rodney.  Now, if you don't plan on going with us...” she motioned down the hall.

“Right.” he said, and headed out.

A few minutes later the last of the crew had returned to the surface, and SG1 had gathered on the bridge.  After a quick jump to a system a few thousand lightyears away, they ran a few scans to make sure they were in the right place.  The system was on the edge of a plasma nebula and had an inhabitable world, matching the description of the system that LeFay had told them about.  Sam ordered the activation of the ARD and a few seconds later the view outside shifted to reveal a large space station a few hundred thousand kilometers away.

An alarm went off on DS9 after detecting a ship appearing in system.  Kira ordered the station to go to Red Alert and the crew ran to their stations.  A few seconds later Captain Sisko walked out of his office.  “What's the problem?” he asked.

“A ship just appeared on our sensors, 260 thousand kilometers from the station.”

“Decloaked?” he asked.

“No.” answered Dax.  “There WAS a subspace energy surge, but it doesn't conform to any known cloaking device.”

A console beeped.  “We're being hailed.” said Kira.

“On screen.” said Sisko, and a human woman appeared on screen.

“I am Colonel Samantha Carter aboard the Odyssey.  To answer what you are no doubt wondering, we are from another universe, the same one Adria is from.  We are here to stop her.”

“I'm sorry.” Sisko replied. “Adria?”

Daniel Jackson stepped forward.  “Maybe you know her as something else.  Maybe the Orici?”

Sisko's face changed as he realized how important their arrival could be.  “In that case, I believe you need to dock with the station so that we can talk.  Major Kira, end red alert and send them docking instructions for one of the upper pylons, as well as station regulations.  Once they come on board, have them escorted to my office.”

Carter nodded, and cut the transmission.
