Yes, this is my first attempt at a fan fic. What do you mean, you could tell? Please be nice. I know it's short, but the chapters will get longer (promise). I'm planning on having as many crossovers as possible, but I won't give anything away. Brownie points go to everyone who notices the extra characters I've nicked, and bonus points if you can name the place I got them from. Please review, but I know there really isn't enough to review. Next bit will be up asap, I promise!

I am also really sorry if some of my pitifully sad humour leaks into the story- I'll try not to let it happen too much.

No, I don't own anything, so can this be my one and only disclaimer for the story? I don't own Stargate, Harry Potter, The Wizard of Oz or any other characters that wander across this screen.

Toto, I've a feeling we're not in Kansas anymore.

In Area 51, alarms were ringing. The obligatory flashing lights flashed. Nameless guards thundered down the corridors towards the intrusion.

Colonel Potter wiped a hand across his face up in the control room from where the intrusion had been detected. He'd taken this job as a favour. He only had to command the facility for a month, and then he'd get the retirement he'd always dreamed of. He could go back to Missouri and teach his grandson how to ride. Now he had to deal with strange men appearing in the middle of the day in one of the most secure parts of the building.

"Permission to report, sir." Some captain was standing to attention in front of him. Potter nodded wearily. "The intruder has been apprehended. He doesn't appear to know what happened. He says he fell through something. Keeps muttering about veils and someone called Harry."

"Was it the quantum mirror?"

"Quite likely, sir."

Potter smiled. "Well then, that's not our jurisdiction. Get the SGC on the phone. Tell them they're gonna have a visitor."

General George Hammond looked around the briefing room at his flagship team, SG1. They'd saved the world on countless occasions, and yet they never asked for pay rises. Personally he thought they could at least have asked for a snooker table.

"So, sir, why are we sat here this fine summer's day?" Colonel Jack O'Neill. Damn fine soldier, and good leader, but still an idiot at times.

"Area 51 had a visitor this morning. A man in a robe came through the quantum mirror. Doesn't know what happened to him. Of course, since the whole NID 'misappropriation' thing, anything that happens in relation to objects brought through the Stargate gets reported to us. He's being held downstairs. Colonel, I want you and Dr Jackson to interview him. Find out what you can. And please, try to be tactful."

Jack stood and saluted jauntily. "I'll try sir." And with that he left the room, Daniel Jackson following on behind.

"Jack, could you leave the talking to me?"

Jack stopped and turned. "What do you think I'm gonna do? Beat him to a pulp and reduce him to tears?"

"It has been known," Daniel muttered.

Sirius Black sat in the tiny room. It matched his mood exactly- blank and depressing. He didn't know where he was, but it certainly wasn't the Ministry of Magic. They didn't have big guns and speak with American accents.

The last thing he remembered was fighting against the Death Eaters- more specifically, Bellatrix Lestrange, his cousin. She missed him with her first shot, but then the second…he remembered being hit and falling…through a veil…

Harry! What happened to Harry? Dumbledore was there, sure, but would he be able to defeat Voldemort? Sirius was suddenly hit by a wave of guilt. James and Lily had appointed him to be Harry's godfather, but now he'd abandoned his duty.

The sound of the door opening brought Sirius partway out of his despair. His eyes widened as he saw someone he'd never expected to see again.

And that, my dear friends and associates, is it. For now, anyway. Please read (but if you're down this far then you must have done just that. Thanks). Who is the mysterious person Sirius recognises? Will he recognise Sirius? Just how many Wizard of Oz quotes will I be able to use as chapter titles? Find out next time on Daz (don't worry. I doubt anyone beyond me will get that joke).
