Before Atlantis moved to its new home, the team went to a small planet out of the farther reaches of the Pegasus Galaxy called Ombri where they were greeted by beautiful women, drink and music. One of the dancers was a young woman names Serah, who caught the eye of Ronon Dex. Politely excusing themselves from the festivities, the Atlantis team headed back to the Stargate. Before they could get there, Wraith darts came through and began attacking the village, and the team was powerless to do much but try to get as many people as possible through the gate. One of which was Serah, who was stunned as she ran out of the woods.
So, pretty much everything about it is the same, except Serah is part of the team as well.

The plot line would follow the plot of the series, with the Wraith and the Replicators. I hope this goes well! The characters go on a first come, first serve basis. So just put what character you want.
