Walking Through

A Harry Potter and Stargate SG-1 Crossover

Chapter 1: Beyond the Veil

There was a small period of time after the war where Harry held enough sway that he could have pushed for any change unopposed. However, he was not interested in the political and instead asked for a job as an unspeakable. His request to study the Veil alone was met with questioning glances and raised eyebrows but no protest. Although there was some concern about his mental health due to the nature of the request and his past with the Veil, so as to alleviate these concerns he allowed for one assistant. Someone who hadn't taken part in the war.

At first the Veil didn't particularly interest Harry. Years' worth of research had already been done and the findings were rather unexciting. Anything going in disappeared and did not come back. Granted, at times whispers could be heard emanating from the Veil suggesting there might be something to it. Yet they were without rhyme or reason and when something did pass through, the Veil could be seen fluttering as though in a high wind. No, the Veil was not the reason he requested this position. Rather he wished to watch the Ministry while simultaneously keeping out of the public's eye, and watch he did.

At first, progress was slow, people were coming around to being more accepting of things. Everyone had their mind on the recent war so when a proposal was made it was usually met with tentative agreements. This held for a while, and it was around this time that Hermione joined as a rising star among the Department of International Magical Cooperation. She fancied herself a peace maker now, someone who in time could rise to the position of Minister and on the way strengthen ties with magical communities. Ron of course became an Auror, while at first, he was disappointed that Harry had not joined him. He quickly overcame it and was secretly pleased he could shine in his own light. Harry watched over them both, sometimes in person and sometimes from afar. If they ever had any issue from an opposing party not playing fair then Harry would step in and the problem would disappear, some would say like magic.

When he wasn't wandering around the Ministry or with Ron and Hermione, he was down on level nine with the Veil. Not studying it of course, rather just doing whatever he desired. Some days he would study on the theory of magic, others he would practice it. He picked and dropped projects like it was a pile of Chocolate Frogs. He was happy doing it for a little while, to work at his own pace without any Dark Lords pressuring down on him.

Eventually he grew tired of the routine because as ridiculous as it sounded, he longed for adventure again. Hermione was closing in on her seat as Minister and Ron wasn't too far behind with the Head Auror position. It had been nearly three years and the Ministry was practically a bastion of stability now, with those two running things it would be a great success or a colossal failure. Harry tried not to think of all the trouble they – as a group – had caused, he trusted them to make it work. While it wasn't perfect and it would never be. It was the best they've had in a long time. Harry was ready to move on. To explore the world in hopes for something new and interesting.

It was a week after his twentieth birthday and Harry had made up his mind. He was leaving, he had casually mentioned the possibility of traveling and seeing the world at dinner with Hermione and Ron. They had been supportive with the rule that he stay in contact, which he could agree to. So now he was down in the chamber with the Veil packing his things and tying up some loose projects or rather that was what he was doing until the Veil started flickering erratically, wisps of energy lashing out at the nearby stonework. Abruptly stopping his current task, he looked at the archway that he had ignored for the past three years. All this time he had ignored it for a myriad of reasons, one of those being his lingering bitterness for taking Sirius away from him but he tried not to dwell on such thoughts.

Intrigued he approached the Veil, he tried to recall if something like this had been reported happening before but he couldn't remember, perhaps something would come through? As he got closer, the whispers which were normally so quiet, were not quite louder but perhaps harsher. As if all the voices were attempting to speak deeply. He quickly cast Sonorus and pointed it at the Veil. The whispers became louder yet it was layered in static, like a bad signal. Harry could pick up on some words but nothing that seemed to form any coherence. He was about to give up for the moment and go research the matter further until he heard a word from the Veil, one that had him extremely interested.

Lise was a smart person, or at least she thought of herself as one. When the war struck, she fled with her family and left the matter to be resolved by others. She had no combat skills and the very thought of actually being in a war zone made her sick. Her mother and father had felt the same way so they had done the simplest thing and left. In leaving she managed to avoid what would have been many hardships for her family and when the war was over, she also managed to secure a job as Harry Potter's assistant. Yes, Lise would say she thought of herself as smart. So, when she arrived to the ninth level of the Ministry and entered the chamber with the Veil only to be met with the sight of Harry Potter leaning against the ancient archway, ear pressed up to the stone, hands caressing every worn line and curve. She couldn't quite understand what was happening.

"Sir?" She asked slowly, unsure if she should be disturbing him.

Harry whipped around to her and for a moment he looked like he had been caught doing something he shouldn't have but he soon recovered and offered her a smile. "Lise, come see this," She approached only confused now.

"Did you find something?"

He ignored her question or maybe he didn't hear it because he asked her a question instead. "What do you hear?" Then he pointed his wand at the Veil, a Sonorus making the whispers louder. She heard as she usually did, the random chaos of whispers. Words scattered about without reason.

"Nothing," She admitted.

He looked at her oddly. "Nothing?"

"Not nothing." She corrected, "Just nothing new. The same whispers from last year and the year before that."

He was shaking his head before she had even finished her sentence, "You're not listening. Take your time and really just… listen," He was the Harry Potter, so she did. She took a breath, closed her eyes and calmed herself. She tried to listen for whatever he might have picked up on. At first the same whispers came and went but as the seconds prolonged, she then caught a word that seemed interesting given the context of the Veil.

"Gate." She finally said, opening her eyes in the process, "As in gate to the other side, the land of the dead," She elaborated.

Upon looking back at him she saw he had that infuriating grin over his face like he usually did when he had an advantage over someone or he was close to getting his way. "Close," He encouraged, "But there's something before it, try again."

So, she closed her eyes once again and took another breath. She tried to pick up on that word again but sometimes it came faster than other times and she wasn't always prepared to hear it. Eventually the other words seemed to drown out and she could only hear what she wanted, she tried to really concentrate on the word as it came for that earlier part. It seemed just like hissing to her but she kept listening determined to understand it. Her brain started to associate it with words she knew.

Scar-gate? No.

Spar-gate? No.

Star-gate? No – Actually that one was possible however unlikely, she opened her eyes and stared puzzled unsure if she had correctly deduced what he wanted. At Harry's grin which had grown larger, if at all possible, she thought herself surer. "Stargate?" She questioned.

"So, you hear it too. Do you know what this means?" he said this as he stepped back to take in the entire Veil as a hole.

The implications where huge, but… "Isn't it a bit of a stretch?" She asked skeptically.

Harry didn't seem bothered by the accusation but he was quick to provide his own thoughts. "You know what's a stretch? An archway that kills anything that goes through it for no reason" He lightly tapped his hand against the stone surrounding the Veil like they shared a big secret.

This led to their regular routine, Harry would try to convince her of something and she would argue against it. Sometimes for the sake of arguing.

He turned back towards her, "I think it's a portal."

"If what you're suggesting is true then how come nobody has tried to come through it?"

He shrugged at this, "Maybe it's a one-way trip. Maybe, it lacked power."

"Power?" She questioned.

"Energy," He offered as substitute. "The Veil started flickering a couple hours ago and has been doing so at random intervals ever since."

He ran his hand down the archway as if tracing its history. "My guess is that whoever's on the other side is putting power through their end and we just need to put power through on this side."

Sensing that arguing against this theory any longer wouldn't do her any good Lise decided to support him. "How much energy do you think is needed?"

He shrugged again. "I don't know, I tried to cast a couple spells at the Veil itself and the archway, it didn't seem to do anything."

She sighed and could already tell this was going to be the new project for a little while. "I could go ask around, see if anyone knows anything about creating large amounts of power?"

He spun around to face her as she said this, "That's a good idea, I was reading the notes from the others who worked on this project. They might have had a similar experience and not mentioned it."

Sensing her dismissal, she ended off with "I hope you're right about this, Sir. Walking into the Veil could blow up in your face." She missed the thoughtful look that her words had on Harry as she went to go ask around.

Later that night, people had reported seeing Harry check the Ministry wards for blast dampeners.

Harry was a bit dismayed by how simple it was to sneak into a military base. Granted he had magic, so maybe he was biased in that regard but it really was deceptively simple with the ability to turn invisible and apparition. Kind of just a go in take what you want and apparate out situation. The standard Ministry alerting wards surrounding the base were easy to take down if you worked in the Ministry itself. Anything higher than the standard wards and you would start noticing technology acting funny so it was best to keep it simple for the best of both worlds.

Really Harry couldn't have been happier with how the situation had turned out. Of course, they would notice what they were missing relatively quickly but it mattered little. It would take days perhaps even weeks for anyone to guess or even prove it was him.

Harry had owled Lise to take the day off today, as he didn't want anyone thinking she was an accomplice. He had also sent a good luck card to everyone from his year in the off chance the trip really was one way. It seemed best, he wasn't big on goodbyes.

All of this he thought as he double checked and triple checked the room and the items that he had packed away in his trunk. There was enough of everything to last for a month. He decided to bring all three Hallows. Not that they ever had any special properties when brought together, if anything it was just a title but he didn't trust them in the hands of anyone else.

A few days ago, he had asked around and made his own checks into the blast dampening wards. The wizard who had recently cast the wards seemed fairly certain, with an infuriating arrogance, that it could take a hit from anything currently on earth. Harry prayed he was right, rather for everyone else's sake. If this worked, he might actually end up on another planet.

Harry could feel the adrenaline pumping through him as the Veil started flickering again signaling it was time. He made his way to the small safe zone he had erected before the Veil. It wouldn't last for more than a second or two at most, but that's all he really needed. Taking out the detonator from his pocket he took one last glance at the Trident II thermonuclear warhead.

He just hoped it was a big enough bang.

"They appear to be moving very slowly."

Samantha Carter nodded in agreement not quite believing it herself, "Only from our perspective."

She could hardly believe the week. It was hard to keep track of the time gone at the moment. It started with SG-10 getting stuck on a planet near a black hole and only spiraled out of control from there. Sam almost smiled at the pun despite the situation.

Behind her she could hear Siler call out, "Uh, Captain…" Sam turned around to see the chair and other nearby objects start pulling towards the Stargate. She gave one look to Teal'c before the windows in the control room shattered. Acting quickly, she ran forward and yelled, "Colonel, look out! Colonel!"

She couldn't do anything but wince as both Colonels slowly looked up and registered the falling glass they then slowly looked down and yelled a sluggish, "Look out!"

She knew the glass would hurt but it wouldn't kill them. If any of the cuts were deep there was still plenty of time before they bled out too. Sam watched on as Cromwell slowly climbed back up and set the timer. Now it only needed to be armed. They were cutting it extremely close if they armed it at their current position. Just as the two Colonels confirmed it was set the iris on the gate fell away into the Stargate. Which revealed a spiraling event horizon, Sam could almost admire the beauty of it if it wasn't so life threatening.

Without the iris the gravity pull was even stronger and both men fell slightly closer to the Stargate. She lurched forward along with Teal'c but there was nothing they could. She tried to squint her eyes as if it would give a better view of what the two men were doing. Sluggish yells of "Climb!" and "Arm the bomb!" Were ringing up to the control room just as Cromwell's rope snapped and he hung off of Jack like a lifeline.

She was too enraptured to even say anything. Her CO seemed had forgone everything and was simply trying to hold the weight of two men at a severely increased gravitational pull.

Just as it looked like Cromwell might let go, the Stargate started flickering erratically. The rope currently being pulled towards the Stargate started swaying as if losing its pull and that's all Sam needed to burst into action.

She started reading the information off the computer monitor in front of her but before she could understand what was happening the Stargate event horizon lit up in a blindly bright light and then abruptly shut down.

Looking up into the gate room Sam couldn't even begin to list how impossible the situation was.

Someone had stepped through the gate.

Traveling through the Veil was interesting. Harry likened it to walking through a blizzard. When he stumbled through the other side, he found himself standing in a building or bunker of sorts. The walls were all concrete and it all seemed rather depressingly grey. That's when he looked behind him and noticed the giant ring which could be the only reasonable thing he could have come through. It looked nothing like the Veil but perhaps it didn't need to. Looking back to the two military men who were starting to sit up he couldn't quite keep the grin off his face.

"Sorry to drop in on you like this. I was looking for the loo," Harry gestured to their current situation on the floor but it was clearly lost on the two soldiers who were still trying to get their bearings.

Harry found that he couldn't exactly tell them apart. They seemed to look fairly similar and found it was easier to identify them by one wearing a short sleeve and the other wearing a long sleeve. After a moments inspection he heard short sleeve say.

"Sorry, this is an exclusive club, members only. Ow…" Short sleeve was clutching his head in a kneeling position trying to right himself. Harry liked him.

The other was sitting with his arms resting on his knees, looking at Harry with absolute distrust, when he opened his mouth Harry found he didn't really like him.

"I am Colonel Frank Cromwell, this Colonel Jack O'Neill – United States Air Force. Identify yourself!"

At which point the half sphere looking object between the two men let out one beep and the counter immediately started going down.

"Is that a- "

"A bomb, yes," The now identified Jack O'Neill said, he sounded like he was catching up with the situation.

"It's counting down," Harry commented.

"It does that," Jack replied.

As the seconds counted down to the single digits, Jack couldn't really find it in him to kick his ass into high gear and try to get as far as possible. Nobody seemed to move, their last couple seconds alive was to be spent staring at a countdown timer, and as the timer hit three seconds Jack watched it disappear before his eyes. The silence that followed was longer than three seconds and he couldn't help but wave a hand through the space the bomb used to occupy confirming that it was gone.

"That's a neat trick," He said really looking at their guest now.

"Thanks, it's trickier the more complicated the object is," Harry replied twirling his wand away.

"What'd you do?"

"Vanished the object into a state of non-being, which is to say, everything."

At Jacks blank stare Harry couldn't help but grin back.

"Yeah I don't get it either, basically the bomb doesn't exist anymore."

Jack replied by giving a nod and letting out an 'Ah' as if that explanation made sense.

Harry was interrupted from answering with another quip when the blast doors opened and a pretty blonde along with a tall stoic man entered. The blond carried a sidearm and the man carried a sub-machine gun, both of which were pointed at him.

They didn't do anything but stand ready in case things looked like they would turn south. Jack who at this point had managed to stand looked at his second in command, he waved her over and said, "Relax Carter, and for god's sake help me out here."

She hadn't been privy to the bomb scenario a minute before and hesitated, "Sir?"

Jack looked back to her and then to guest that had somehow walked through the Stargate from a black hole to which they were dialing.

He gestured to the guns being pointed at Harry "Do we need these?" The unasked question if Harry was a threat was obvious.

Harry made a face that said he couldn't think of anything that would merit guns and shook his head.

"See there you go, now stand down and help me walk to the good 'ol doc," To which Carter lowered her weapon and helped her CO while Teal'c helped Cromwell. She informed Jack that she had sent Siler up to the surface with the news. Personnel would start filling down in a couple minutes so they could wait in the infirmary.

"You're all American," Harry said.

Jack who seemed to have taken charge of conversing with him, replied.

"Oh, so you've heard of us."

"Yeah, never been to America though."

"You're British then?"

"From England, it was quite the trip actually."

"Oh, I'll bet. What did you say your name was?"

"Potter, Harry Potter."

Jack couldn't contain the snort even if he'd wanted to.
