Dudley isn't going to be that fat in the story, mostly because the Dursleys found out how bad that would be for him and their image among society, and they where they will be living will not allow it and it would be even more dangerous. Likewise, Dudley is going to be close to Harry similar reasons. Now, lets get onto the story!

Summary: Accidental magic is relatively unknown, it's limits and everything possible when a magical child's fluctuating emotions 'activates' it for lack of a better term, especially what happens around electronics and machines seeing as there are no recorded incidences of it around muggleborns, and pure-bloods rarely even see things like that. When you take into account a room filled with broken objects and a half-built product of a child trying to build a machine and very intense emotions of two six-year-old magical children, you can get very interesting results. Or, you could get transported to another world very different from the one you were in.

When Vernon Dursley arrived home, he was very drunk after a potential business contract that failed. As such, when he got there, he was in a very foul mood. He had intended to drink a lot more and go to sleep, but he heard something on the way to the room, and in a stealthiness not befitting someone of his... girth, he climbed the stairs to the second floor. What was there had him seeing red. The freak that was forced on them from the other freaks was teaching his son how to do magic! And succeeding! There were parts of different objects floating around the room! He knew it was a mistake taking him in! It was bad enough he had corrupted Dudley into being friendly, but this was unacceptable! The freaks were probably watching, but he didn't care, he would beat it out of both of them if he had too!
Now, it has to be said that 'Mr. Dursley' was drunk, furious and thus not in his right mind right now. As he started over to them, very loudly at that, it has to be said Harry Potter and Dudley Dursley were very scared. Now, magic is a curious thing, relying very heavily on intent and emotions,which is the main reason accidental magic was so strong. Most children are very emotional at young ages and their 'cores' haven't settled, leading to it being a lot easier for their emotions to affect their magic. At the moment when he started hitting them, they had clung together in hopes of it lessening their pain. This was very important as what happened next would not have for a few reasons.
1, something like this had not happened before because the injuries would be too noticeable and the Dursleys' wanted to keep the perfect family act going. 2, because something like this had never happened before, the emotion shared between them were very much intensified, those being mostly betrayal, fear, and pain. 3, while Harry was teaching Dudley very small magic, he didn't really have a core. He was more drawing on the ambient mana in area and the blood-wards, giving him a 'fake' core as it were, seeing as he was drawing into himself, storing it in where the core would be in a wizard or witch. An area that is usually empty in muggles. This is interesting as it would not be possible other than in that family, only happening for Dudley because Dudley was kind to him and thus was able to draw on the blood-wards. 4, all they could think about was the pain and wishing to be as far away as they could. 5, they had been messing around with things earlier, and made some kind of cross between any electronics they could find. Normally this wouldn't do much, but the 'Potter Luck' is a cliche for a reason.
What happened next was amazing. With the blood-wards fueling that wish along with the magic to take them anywhere else, it went through the barrier between dimensions. And because Vernon was in contact with them when it happened, he was pulled along to. What happened was every directional and movement contradiction you could think of happening to them all at once. The only reason that Vernon hadn't fallen down was he was too drunk to think about what happened properly and was braced against them when he had hit them. Another interesting thing about side-effects of that trip was the Horcrux in his scar was destroyed, because of the influence of Meridia on Nirn which is the reason that necromancy spells eventually fail. Her nature is very much against undead, with out the presence of one that counters that, it degrades anything connected to necromancy. As it was created by the willful killing of someone to split their soul to try and gain immortality, it was close enough and was to little an piece of a soul to offer any resistance. On another note, because of the amount of mana flowing through them both at that point in time, along with the use of mana in the blood-wards, it connected the cores of both kids and made it so Dudley's produced it's own when less than full, making him a true wizard. The blood-wards themselves came along for the ride, and were bound to the children, although they weren't meant to defend against anything of this world, so they weren't really of any use as long as they were there.

When they arrived they found themselves in Whiterun, in the middle of the main hall of Dragonsreach. When Vernon tried to attack them again, he was restrained. He hit the guards away from him screaming about freaks. When he started hitting the kids again, they were disgusted. They were only children. They decided altogether in an instant he didn't deserve to live. When they got close enough, he was stabbed through the heart, what little they thought he had left. After all the events in the day, along with watching Vernon being killed right in front of them, they passed out.

Harry woke up very early, with the sun shining strait in his eyes. One of the guards noticed and went to bring the Jarl. While Harry was looking around at the unfamiliar place and remembering what had happened, the Jarl had arrived unnoticed. "Finally up lad?" Harry jumped when he spoke and whipped his head around to find where the voice was coming from. "Calm, child, I am Jarl Balgruuf. Now, mind telling me you two are and how you got here?" Harry thought on that for a minute, but his natural childish innocence and politeness that is practically ingrained in his blood overcame his wariness. "My name's Harry Potter," the Jarl showed a slight recognition to the name Potter, but Harry didn't notice. "and this in my... adopted? Cousin Dudley Dursley."
He seemed to be thinking on something for a moment. "You both have a few options available to you now. One, is be trained by the companions, the best fighters in all of Skyrim, although you cannot join them as you are too young. Two, for you especially, Farengar has offered to teach magic. The third option is being trained by both. It will be a lot harder if you decide to, and you will be expected to keep an grow in both." he finished muttering something about 'legendary potter luck' and 'family sticking together'. Dudley slowly started to wake up, and Harry started to rapidly, and childishly, explain all of what they had talked about. After, they both choose option three, with the base their training schedule of what they show the most promise for.
After they had made their decision, they were introduced to Irileth and Farengar, along with the Jarl's children. Soon after they started their training. Both of them seemed very interested in learning magic, although they were also exited to learn how to use weapons. That wasn't exactly what happened though, seeing as how they had to get to an appropriate level of strength before they even started on the basics. They quickly grew to hate their trainer in weapons, even if they knew it was necessary.

It had been two years now and both were 8 years old, and quickly advanced in everything they learned, although it was very obvious that their strengths lied in different areas. Dudley was better with a waraxe and shield and preferred heavy armor over light, and was very much a 'tank'. Harry was very obviously better as a mage, although he still was proficient with daggers or short swords and light armor. He was also more talented in the schools of restoration and illusion, and his reserves were absolutely massive, while Dudley preferred alteration to increase his armor rating and didn't have nearly as much magika. They both had conjuration spells for their respective weapons, although Harry preferred to create spells for the both of them to use.
Examples of spells he had created are restoration spells that damaged their enemy's or, if they didn't strait out heal allies, didn't harm them and just passed through, since it was discovered he couldn't cast destruction spells without something... weird happening. How did it animate several loafs of bread to attack them they will never know, seeing as how he didn't do much with conjuration. All his spells were connected to a major spell that acted like a transparent computer screen and keyboard that floats in midair. He called it Archive and it was another spell he created based of something similar he found in a book somewhere, although it lacked most of the telepathy aspect and added a passive ability similar to a video game interface, giving him the option of having a 'party' and showed health, magika and stamina in bars near the bottom of their field of view in rough approximation of current levels in red, blue and green respectively.
The passive party aspect of the spell is usually limited to him and Dudley, although he can make that go to around fifty people before it starts to drain his reserves faster than he can fill it back up. Although it is similar to games with something similar, everyone else in his party can't see each others remaining status, that is limited to when he uses the T.C.S. (Transparent Computer Screen), in which it has each separated into distinct rows and columns for each person. They tested with Farengar to see how long he could use Active Archive, with the activated T.C.S. and keyboard, and he could barely hold it for around a day, while Harry could use it for around a month strait.
He had a larger amount of raw mana and mana regeneration speed than just about any High-Elf, let alone his fellow Bretons! Ah yes, about that, when they had arrived in Skyrim, their races changed. Harry became a Breton, and Dudley a Nord. Anyway, the spell matrix is large to the extreme, and the only reason it worked anywhere near as well as it does is that was created with as much efficiency as they could put into the thing. For the passive effect, Farengar can only keep it up for about 5 or 6 people until it started to drain him. It took all the best and most knowledgeable mages on spell crafting they could find, along with the best part of a year, to create it. Pretty much the only reason Harry's reserves are as large as they are is because he both parts of the spell active for as long as he could, and his body adapted to that.
As for the damaging restoration spells, all it's doing is targeted growth in or around a targets body, combined along with the known method of sun damage that works on undead. They are more effective on undead, like with sun spells, but it also grows certain parts of the flesh inside or around a targets body when it doesn't just damage them like a normal sun spell does, for example, growing something akin to a tumor to block the flow of blood to an arm and stop it from being used, at least used easily, or regrowing the arm itself. It is also possible to the energy from said tumor and replace that elsewhere, evidence to the saying healers know the best way to take you apart. It's even worse with him since his specialty is targeted healing, and needs a much greater depth of knowledge of the human body. So, while he is essentially a tactical healer/party master, and Dudley did very well as a tank, they didn't have any other constant party members to fulfill the other positions that are usually found in a party. All-in-all, a very terrifying party, but without most of it's members. And it's also mostly theoretical, the only real spell he has completed is Archive, and the restoration one's, or at least most of them, are either being only thought of, being figured out/ figuring out how to fix problems, or in any stage in between.

Albus Percival Wulfric Brian Dumbledore, a very old wizard at the age of 147. Not the oldest, but certainly up there. And for the past two years, he had been feeling almost every second of his age. The reason? Harry Potter, the hero of the wizarding world had been missing. The only upside was he knew he was alive, otherwise his name would have been erased from the book of future students. Not very imaginative, he knew, but it wasn't him who named it. He had been pressured by everyone in their little hidden community to try and find him, each for different reasons, some because they believed it would be easier to target/kill/discredit/kidnap/turn him to their side. Others because they just want him safe, or to meet him, or get him to love them with or without love potion, and a near infinite amount of other reasons. Now he had hope, he had found him.
It felt as if a giant weight was taken off his shoulders. He had know Harry's aunt was not the best place to put him, but anywhere else and either the blood-wards would not have worked, or it would have been all to easy for any of the wizards to find him. If the first happened, or somehow did work and failed, they had no clue what the backlash could do. He had known that Lily's sister was adopted, but the name 'blood-wards' is misleading, as blood magic ran off the spirit of a person not their actual blood, but the best medium is blood. And for the second, it would be all to easy for someone from a family that served Voldemort to capture him. If that happened it might break fate, and if not, Harry and Tom on the same side would be disastrous for them. He didn't like playing chess master, but it was the only way he could keep the wizarding world from being destroyed. Especially from the muggles. Oh, nothing they had could harm them immediately, but the wizards have no way of defending against radiation from a 'nuke', especially seeing as they saw no reason to find a spell to do something leftover radiation because they didn't think it could harm them.
But, he had finally found Harry. There was no reason to send him back, seeing as the blood-wards were bound solely to the bond between Harry and Dudley now, and he didn't see how any of the other wizards would be able to find him on a different dimension, or if they could, how they could reach him. He wouldn't even have tried it, but he had gotten frustrated and told Fawkes to search through dimensions for all the good it would do them. Turns out bonded Phoenix's' needed to be told by their masters if they want to cross dimensions. Interesting, but irrelevant. He had seen how far Harry had gotten, and was impressed. The mages' of that dimension even gave him a title, Archive, based off the spell he was know to use. Even if he was just one person who worked on it, he still did a lot of the base work on the spell with the others adding onto what he had done, and it would have been impressive even for several adult wizards! He was certainly going to be either a Ravenclaw or Hufflepuff, his loyalty to his cousin was very well known after all.

Ok, so that is the start of the story. Fist thing to do is address possible concerns. No, Harry will not be OP, he will be a powerful wizard/mage but he won't be invincible, the more magika you have only means you can cast more spells. Any adult wizard/mage will be able to defeat him relatively easily if they know the basic stunning spell, as wizarding spells will not be stopped by mage wards, and vice-versa. Another thing, while he prefers to create and use his own spells, that doesn't mean they are any better or worse than normal, and the spells he is trying to create alone will be very difficult to complete. By the time he goes to Hogwarts, he will have only crafted one or two of his specialized healing spells, and they won't be good enough to use just yet. His Archive falls under the school of illusion, seeing as how it affects the mind. Also, legimancy won't work on him properly, because he structured his brain similar to a computer in order to use Archive, which is another reason Farengar will not be able to use Archive to it's full potential. His brain can't control and keep track of all those things happening all at once, but Harry's can. And, when the Jarl was giving them their options, all Harry could understand of that was, 'learn sword, magic, or both?'. Anyway, that's enough from me for now, I'll see you when I update again.
