Chapter 1 – Invasion

It was the first week of July and Harry was in his room on Privet Drive, with a visitor. Ginny Weasley had joined him there earlier that day to find out what was going on, as Harry had not answered any of the letters sent by herself, Ron, Hermione, or Remus.

After Professor Dumbledore had told him about the prophecy, Harry had gone into a deep depression because his life was going to come down to a battle with Voldemort and only one of them would emerge victorious. When Professor Dumbledore found out about Harry not answering his mail, he sent Ginny to pay Harry a visit after sending him a letter telling him he was free to discuss whatever he needed to with her. Harry could see the underlying suggestion; he should tell her about the prophecy. Just as Harry finished explaining the prophecy to Ginny, which included the fact that the whole war would come down to a battle between him and Voldemort; a battle that only one of them could survive, there was a knock at the front door.

When the pair heard this, they both looked out of Harry's window, and saw a group of four people at the door. Two of the group were known to both Harry and Ginny; Remus Lupin, the third year defense teacher for Harry and Tonks, who was a member of the Order of the Phoenix and an Auror. This only made up half the group that was on the doorstep though, there was also a blond woman who was about the same height as Tonks and a man who looked strangely like Harry's father James Potter. However the man at the door was obviously not James as he had brown hair that was just as Messy as Harry's own and eyes about the same shade. The pair inside did not have time to ponder this as suddenly there was a shout from downstairs, "Get the Door Boy" Roared Vernon Dursley.

As Harry ran down the stairs with Ginny following him, Harry started to wonder why Remus and Tonks were at Privet Drive so early in the summer and who the two newcomers were, especially the man who looked so much like James Potter.

When the Pair reached the bottom of the stairs, Harry was feeling quite pleased as Remus and Tonks were some of the few people that Harry felt able to talk to about Sirius as all three of them were going through the same thing. Remus and Sirius were all the other had left from their schooldays after the betrayal of James and Lily by Wormtail, and Tonks was Sirius's Cousin. Remus was now all that was left of the Marauders and Harry's last link to his parents and now Sirius as well.

When Harry opened the door, he asked "Hello Moony, what brings you here?" Remus said "We need to speak with you and Ginny urgently. Is it alright to come in?", "Sure" replied Harry "Come on in, I'm sure we can commandeer the lounge for a bit" he finished with a meaningful glare at Petunia Dursley. "Use it" she hissed "But be gone by the time Vernon's client arrives."

When the group had all taken seats Remus said "Harry, this is Daniel Jackson and Samantha Carter. There is a hell of a lot to explain here, and some of it will be unbelievable but it is all 100% true."

"Ooooookay" said Harry, not really sure what was going on.

"Harry, Daniel is your uncle. He is James's older brother." Said Remus

Harry was stunned, why did nobody tell him, why were there no pictures of him in the photo album Hagrid had given him in his first year.

Sensing that Harry was about to explode Daniel said "The reason no one mentioned me is because I never went to Hogwarts. Hardly any of your Fathers friends knew about me."

"How come?" asked Ginny

Taking a deep breath, Daniel replied "I never went to Hogwarts because I cant do magic. I'm a squib."

"Still, how come there were no pictures in the album I got in the first year?" Harry asked

"Well after your grandparents were killed, I was kind of bitter. Around this time I was just about to complete my doctorate in ancient civilizations and I received a letter from James telling me to go into hiding because he found out Voldemort was going to go for the rest of the Potters. So while I was traveling I dropped the surname Potter and just went by my first two names Daniel Jackson." Answered Daniel.

"For you to understand the next bit we first need a little history lesson" said Samantha

"In 1920 there was an archeological dig at Giza in Egypt. A large metallic ring was discovered by the team and moved to america for further study because it was made of an unknown element" said Daniel.

"Seven years ago, Daniel was shown the ring, and started to translate some writings found with the artifact. From these he discovered the name of the device and it's function" continued Sam

"In the text I translated it was referred to as a gateway to the stars, so it was dubbed a 'stargate'" continued Daniel.

"And what does the Stargate do?" asked Remus, who was as interested in the story as Harry and Ginny.

"Sam, if you would…" said Daniel "She can explain the science behind the stargate better than I can" he added to the rest of the group.

"The Stargate creates a stable wormhole between two points in this and a few other galaxies. As you step through the event horizon, you are transported instantly to the other gate" Sam explained.

"Basically the gate works like a giant interstellar telephone, but instead of transmitting sound, it transports people" said Daniel "Now you know what the gate does we can finish the explanation" he finished.

" In the texts Daniel translated there was an address, and when we discovered that the gate was active a team of marines accompanied by Daniel were sent through the gate" said Sam.

"Basically the long and short of it is, we discovered that the people who lived there were oppressed by another race known as the Gou'ald." said Daniel "They, for the most part take the persona of an Egyptian god." Daniel continued

Harry Interrupted "Sounds like Voldemort" he said

"The Gou'ald are parasitic beings. They actually look like snakes, but are capable of entering and controlling human beings" said Sam.

"The gou'ald on the planet we visited had taken the persona of Ra, which is the Egyptian god of the sun. Thanks to Colonel Jack O'Neill, we sort of sent a nuclear warhead into his face." Daniel continued "Instead of going back through the gate to earth, I decided to stay. But a year later things kicked off again." He finished.

"On earth there was an attack on the facility from people who came through the gate its self. At first it was assumed that the attackers came from the first planet we had traveled to, as at the time it was the only known location that the stargate connected to" explained Sam, "Colonel O'Neill was pulled out of retirement, and after sending a message through the gate he and another team of marines were sent through the gate to find out what was going on and to retrieve Daniel" she continued.

"Whilst I was showing Jack and Sam what I had discovered during my time on abydos, my wife and her brother were kidnapped and taken through the stargate" said Daniel.

"What was it you had discovered?" asked Ginny, who was hanging on every word of the story being told.

"Well in a temple not too far from the village where I lived, I had found what turned out to be a massive list of stargate addresses. After seven years we haven't even got a quarter of the way through them all" answered Dr Jackson.

"So basically small teams of the US Military travel around the universe using wormholes, and explore other planets? Sounds like that lame show Dudley used to watch, Wormhole Xtreme or something…." said Harry.

Suddenly there was a short burst of static, and then an authoritative voice said "Hey, the show wasn't that bad."

"Who's there?" asked Ginny, unsure where the voice had come from.

"That was Jack, on the radio. He's on guard outside along with Teal'c and a couple of order members" said Daniel.

Suddenly over the radio there came a burst of gunfire, and then a shout from the same voice, "Carter, Daniel we got hostiles incoming at 3 o'clock!" before Sam could reply however a strange sizzling sound was heard. "EVERYONE DOWN" yelled Carter, just as the front door to the house disintegrated into fragments of wood. Just seconds after that a blue flash shot through the hall and a heavy thump was heard.

"Zat fire" said Daniel "Sounds like they got your uncle. Don't worry, one shot only stuns so he's going to be fine."

Seconds after the flash two men started backing through the non-existent door. "You three get the normal occupants out" one of the newcomers yelled at Daniel, Sam, and Tonks "The rest with us, we need all the fighters we can get" He continued.

As Harry, Ginny and Remus moved over to the Hall, Harry caught a glimpse of the forces congregated outside; he saw a massive crowd of Death Eaters including Lucius Malfoy and Bellatrix Lestrange. However, instead of casting curses at the house and its occupants, they were firing strange looking weapons at the place.

"Lupin, apperate to order HQ and see if you can bring help." Said the man Harry rightfully guessed was Jack O'Neill. Once Remus had departed Jack continued "You two, with us. Lupin said you were excellent fighters, and right now we need the manpower" he said, "Your shield spells wont stand up to zat fire or a staff blast, so you need to be quick" continued the Colonel.

Harry thought for a moment and grinned "Accio Firebolt" he said. A few seconds later when the broom appeared, Harry asked "Aerial Assault any good?" at this the Colonel grinned "Hell yes" he said "Is there any way of enabling you to weild this as well?" asked the other fighter, holding what was obviously one of the staff weapons.

"A sticking charm should do the trick" said Professor Dumbledore, who had just apperated in with Remus and a few other Order Members.

Five Minutes later Harry, Ginny, Remus, and Tonks were in the back garden of Privet Drive with 4 fighter brooms as they had been dubbed preparing to take off. "Remember, don't fly in formationand dodge anything that is aimed at you" said Remus. All four were armed with the small handheld weapons that the Colonel had referred to as Zats, as well as the long staff weapons fixed to the brooms.

"Now Remember, use the zat as much as possible. We want to take as many as possible alive; the order needs the intelligence" said Remus.

At this the four fliers kicked off from the ground, and shot around to the front of the house, (Both Harry and Ginny covered by a Disillusionment charm) and joined in the battle. Almost instantly the tide of the battle turned as huge swathes were cut into the massive army of deatheaters. It seemed even though Tonks was clumsy, she was still a crack shot with both her wand and the new weapon.

Suddenly, towards the back of the crowd of Deatheaters, Harry saw the one man apart from Voldemort who had destroyed his childhood; Wormtail. Harry quickly communicated the information to Remus and Daniel, then drew his zat, and fired upon the traitor hitting him square on. Following up behind Harry was Remus, who transfigured the Rat into a pebble, and summoned it in quick succession. As soon as the stone reached Remus, he pocketed it with relish.

After another 10 minutes of raining down zat fire, staff blasts, and various hexes and curses, the deatheaters had lost over half their number to stunners, zat fire and the like. The minion who was in charge called out "Fall Back" and the Deatheaters who were still standing Disapperated.

Once the surviving minions had gone, the fighters came out of the house and from cover slowly and congregated in the middle of the front lawn.

"Any Casualties?" called out Jack, taking charge of the situation.

"We had two sir" said Carter "Harry's aunt and cousin. They were caught by falling masonry. There was no chance they could have survived."

Suddenly there was an enraged screech from inside the house "POTTER" and in the doorway of the semi demolished number four privet drive appeared Vernon Dursley, in an apocalyptic rage. Again he roared "POTTER! YOUR MINE." As he stampeded towards the small crowd on the lawn, Tonks quickly cast a stunning charm at him, but it was shrugged off and he just kept coming. Before the man could reach Harry however, Jack O'Neill pulled a zat gun and fired it at Vernon, causing him to drop like a stone.

When the rest of the order looked at him, the Colonel said "What? He was gonna hurt Danny boy's nephew. I ain't gonna let that happen."

Before anything else could be said a corona of white light surrounded Harry, Ginny, Harry's new Uncle and his friends, along with Remus and Tonks, plus a few items in the wreckage of number four, and then in a flash they were gone…
