At first, I wanted to make Harry somehow teleport to Asgards just to be dumped on another more primitive planet. As I read a new crossover, I thought "but why does always Harry get teleported, kidnapped, gone when he's on earth and usually before he's even got to Hogwarts". It can't be cliché because there's not enough HP/SG-1 crossovers to consider anything cliché, but the concept is a little overused.

So, maybe I should modify a little the beginning.

I have some ideas on my mind but I'd like to ask if any of you has a more original idea.

- Once Lily and James Potter learn the Prophecy, they decide to hide. It's just that it's not in Godric Hollow but in another planet they hide. They arrive at (for example Abydos... or maybe another planet not raelly known by the Goa'ulds) and they raise their child. Lily and James are young, full of energy and have interesting powers. People like them. But there's a traitor in this planet. These powerful beings could be really interesting as hosts to Goa'ulds and he sells this information to a powerful System Lord. So, Lily and James are nearly captured; they flee with their five year old son.

Later they could get captured (and not their son), killed or be still with Harry. Harry would grow so to be more mature for his age, could do some little magic his parents showed him, etc.

That's the first idea I got. It could make an interesting story I think. Even to non-Stargate fans it would be interesting because they will learn about Stargate when Lily and James do. Plus, I can still make them have the ATA gene but they don't need to know what that is.

-
The second idea I got is nearly the same except it's a Maraudaur's experiment that didn't work as intented. So we may get the four marauders plus Lily on another planet. And as I don't like young Sirius, Remus and Petter, I can make them killed by Goa'ulds for example.

I don't like the second idea too much though.

If you have any other original idea that I could use to start the story, I would like to know.

 

There's the gateway in the Department of Mysteries goes to one of the SG worlds (in Pegasus in one story).

Other methods of travel could be Floo mis-pronunciation as a mundane way of going wrong, or perhaps a portkey travelling to America (or even Russia) for some reason and then the Stargate activating at the same time, the two wormhole like things merge and the portkey suddenly goes a lot further than was intended.

If there's a magical sosciety on other planets, they may have a magical interplanetary transportation, one way or another HP can stumble upon it and use it... I'm using that method in one of my stories, though it's not a Stargate one.

Flamel is an old guy, he could be working on magical transportation and for some reason (after the destruction of the Stone) he feels HP is the person to guard or further his work.

 

Perhaps you could do it diffrently. Harry is unable to defet Voldemort. However he learns that Portkeys are basiclly wormholes. Harry can not kill Voldemort, perhaps he is no effectivly Immortal or somethign. Because of this Harry decided to 'seal Voldemort away' and basiclly locks him in a wormhole with no exit, so that he can find some way to defeat him.

Harry then because interested in this using wormholes and studies the phenonamal and detects the wormholes of the SGC (though I think this part would be pretty stupid.) Or perhaps as above he gets caught in a wormhole.

Another note, remember that Merlin was apparently an Ancient, however to the HP wizards he is the greatest wizard of the age. What connection could there be that would boot Harry of earth. Perhaps Harry finds intstructions to a supply dump of Merlins only to run into a security feature that shunts him onto a Random plannet.

And now I need to dunk my head in a bucket for comming up with so many stupid ideas.

 

Hum Hum, I don't know.

I like to be realistic in my fanfictions. Well, magic doesn't exist, but let's try to make it as plausible as possible. Ollivanders opens for business in 382 BC. I can safely assume that Magic existed since about 2500 years at least.

The Magical community isn't a big one probably but in 2500 years there's a lot of research and innovations that have been done. Magical transportations are probably quite old too. If there was any chance to be stuck into a Wormhole, it would have been fixed. Plus, I think it's like floo; if there's an error, you get in another place. Maybe six feet under ground and you die then, but you still get anywhere else.

The veil at the ministry can't be a kind of magical Stargate. Harry and Luna heard voices when they were in the room. I'd say it's more a portal to the plane of Death or something like that. I believe though I'm not sure if it's in Fanon, but the Veil is a mean of criminal execution.

Now, the idea of using Merlin could be a good one. If Wizards swear by his name, it's because he probably has done great things. Maybe Alteran technology is as impressive to Wizards as Magic is to the Muggles.

Maybe I could do something with Avalon (season 9); Harry goes (Apparition mistake for example) to Glastonbury and find that it's not Magic but alien technology. So he begins to investigate (while Hermione and Ginny are being squashed by the descending ceiling).

Nicolas Flamel is quite old; maybe he knows something of alien artifacts.

I know Harry's quite dumb. He didn't knew of Magical transportation until the fourth book. But still, if Magical societies existed on other worlds and there was interplanetary magical transportations I think Harry would have heard of that.

 

What Teal_Thanatos was probably saying is that, the Veil isn't the portal to another world, but DoM have some other portal created by Merlin himself. That portal goes only one way (eg. Avalon, Camelot, Heliopolis - castle with universal language). And it gives us a way to establish magical version of Stargate Program, this time run by British Ministry of Magic.

 

What I was referring to was a story (I forget which one it was) where HP becomes John Sheppard, and he finds Sirius Black in Pegasus Galaxy.. People who've been thrown in the portal are randomly expunged in Pegasus... hence people who had been thrown into the veil over a thousand years before Present-Day leave it at the same time as those who went through recently.

Because _noone_ ever came back (it was impossible thought the people who had been put through) the people of earth thought it was an execution device.

-Edit1-
Merlin being an Ancient is used in a couple of stories. Most notable one in the review section right now.

As to the interplanetary method of transportation, I'm having the method of summoning it be quite specific, and it's not exactly possible for wizards to use it twice or more.

 

Merlin was an ancient, thats Star-gate Cannon.
