Authoresses Note: Hi, this is a Harry Potter / Stargate Crossover with the fifth book in the Harry Potter series. It's Season seven in the Stargate universe. Hope ya'll enjoy, and please Read and Review.

Summary: Basically, during one of the DA meetings, something happens to the Room of Requirements and the wall in the back of the room starts to come apart and a bright blue- water like light encased in a circle of stone carved with astrological symbols pulls them through, and takes them to in a new world where there are no witches and wizards, but aliens and gateways to other worlds. With no apparent way home the DA works with the SGC to get back home. This is the meeting where Seamus Finningan joins, but Umbridge doesn't come.

If I misspell someone's name or something, please let me know.

Vote on who ya'll want to be together, but no gay couples okay?

Chapters will be longer later.

Disclaimer: I don't own anything except the plot.

Chapter 1

There's No Place Like Home

"Doing good Neville." Harry Potter is currently going around the Room of Requirements, checking everyone's work and making suggestions here and there.

Everyone's working on Patronus's and are making good progress.

Since Seamus Finningan had joined, he was able to help everyone more.

After fifteen minutes of walking around, he was going back to the front of the room to supervise everyone. Hermione's voice calling him to look at the back of the room made him stop and look behind him. Everyone's attention was directed at the far wall of the room. The wall was shaking with increasing intensity, and a bright blue light was staring to cut through the stone bricks.

"Everyone, RUN!" Harry shouts as the bricks fall apart and a large circle of intense blue light that looked like rippling water is revealed, encased in a circle of stone with constellations on it. Everyone, who had previously been mesmerized with fear at the light, began to run towards the door. They might have escaped had the large blue-water circle hadn't started to pull everyone through. Many clung to something, bookcases and tables, but soon lost their grip and went flying through. Screams for help went on deaf ears because Hermione had cast a Silencing Charm on the room so that no one would be able to hear them as the practiced. As the last person went through, the portal closed. Papers were starting to land on the floor and one particular piece of paper floated onto a table. At the top, written in large letters, were the words,

Dumbledore's Army.
