*Surrey, England, United Kingdom, Earth*
Harry Potter was locked in his bedroom following an incident involving a crazy house elf named Dobby, a plate of Aunt Petunia's pudding, and a levitation charm ended up getting him in trouble with both the Ministry and Uncle Vernon. Multiple locks were placed on the door and bars on the window and his pet snowy owl Hedwig was locked up in her cage. Since Harry couldn't use Magic outside of school, he had no hope of escape nor could he free his owl to send a letter to his friends who he now knew had their letters blocked by Dobby.
That all changed when Fred, George, and Ron Weasley arrived late that night in their dad's enchanted flying Ford Anglia. Harry was able to load his belongings into the back of the car as well as hand Hedwig's cage to Ron. However when Harry tried to climb from his window to get into the car, Uncle Vernon burst into the bedroom, grabbed the 12-year-old wizard by his ankle, and yanked him right back inside.
"Help!" exclaimed Harry right before Vernon slammed his head into the dresser hard.
As soon as Harry fell to the floor dazed, Vernon proceeded in kicking him in the stomach. Before Harry had a chance to recover, he felt his uncle's foot connect with his side and heard and felt the sickening cracking sound of at least one of his ribs being broken. Vernon then grabbed the chair and wielded it threateningly as he stood over his nephew with an enraged look on his face. The Weasley siblings were horrified as they witnessed what was happening to their friend.
"So, you thought you could escape me and go back to that freaky school of yours!? Well think again, boy!"
"No! Leave him alone!" exclaimed Ron as he prepared to climb out of the car and into the bedroom window.
"No wait, Ron!" shouted Fred.
"You keep the car steady..." said George.
Fred quickly continued the sentence, "...and we'll handle this."
Petunia and Dudley began to panic when they saw the Weasley twins climbing in through the window. "Uh...Vernon," stuttered Petunia as Dudley shouted.
"Dad! More freaks are coming in the house!"
Vernon, however, was for the moment ignorant to the world around him as he glared at his nephew with pure hate as he said in a wicked tone, "By the way, Harry. Happy birthday!"
As Vernon started to swing the chair at his nephew, Harry threw his arms over his face and closed his eyes as he exclaimed "No!"
Harry expected to feel the sharp blow from the chair that his uncle was preparing to strike him with instead Harry suddenly saw what could only be described as bright lights. Which was odd considering his eyes were closed. He also heard a very deafening noise in his ears and felt an odd sensation in his abdomen. Even when he opened his eyes, it appeared he was surrounded by the same bright lights and it appeared he was spinning around in circles. The image of stars combined with the bright lights had the 12-year-old wizard mystified and he could only wait until whatever was happening to him had stopped. Eventually the bright lights subsided and he appeared in the middle of a fog-filled forest.

Back in Surrey at that very moment, everyone just stood in place with shocked expressions. One moment Vernon Dursley was getting ready to beat his nephew within an inch of his life. The next said nephew was simply not there anymore. Fred and George just looked at one another with surprised expressions on their faces. Vernon swung towards the Weasley twins with his face now purple with rage.
"Where did you hide the freak? Bring him back now!"
Naturally none of the Weasleys had any clue what just happened; however, they mutually decided that there was no point in hanging around, so the twins climbed right back in the car. Since they were in a bit of a hurry, they didn't bother taking the wheel from Ron.
Vernon stomped over to the window, his expression making it clear that he intended to board the car.
"Drive..." began Fred.
"...now!" finished George.
"Right," said Ron as he began to drive the enchanted car away from the house.
"No left!" exclaimed Fred and George simultaneously.
Vernon attempted to lunge at the car. However, the flying car moved out of the way at the last second and Vernon fell screaming to the ground below.
"Dad!" exclaimed Dudley as he and Petunia ran to the window and looked down toward the ground with looks of disbelief on their faces.
Vernon got out of the hedges that he had landed in and watched the magical flying car depart into the night sky.

Unknown location
Harry stood up and looked around with a disoriented look on his face. From the large number of trees, as well as the heavy fog, he believed that he had somehow apparated somewhere in the Dark Forest. The 12-year-old wizard quickly pulled his wand from his pocket and said the incantation "Lumos", causing said wand to illuminate.
He surveyed his surroundings for several moments as he tried to spot a familiar landmark so that he could make his way to Hogwarts, assuming this was indeed the Dark Forest. While he didn't find any, he did spot some sort of unrecognizable stone structure which was covered in overgrowth plants. A closer look revealed that the structure was an obelisk of unknown origin and adorned with markings which he determined belonged to some long-forgotten language. He was certain that Hermione was going to have a field day studying this structure. Of course, after she chided his ear off for him apparating into the forest, (Acident or not).
Finding nothing else of interest here, he decided to start walking, keeping his wand at the ready for any potential threat. Harry grasped his upper abdomen, which was hurting very badly, likely due to one or more broken ribs. He stopped walking when he heard what sounded like whispering. He listened for a moment; however he didn't hear it again. He started walking again and eventually walked into a clearing in the forest. The fog was not quite as thick out here, though he still was unable to spot any familiar landmarks. As a matter of fact, he began to wonder if he was even in the Dark Forest.
Harry decided to look up into the sky, hoping that he could use the constellations as a means of navigation. After looking up at the stars for nearly a minute, he suddenly realized that he wasn't able to spot any familiar constellations. Instead, the patterns he saw were completely unfamiliar. He had memorized the constellations by heart during his time spent at Hogwarts last year and even the ceiling in the Great Hall kept the constellations accurate. As he continued looking around the night sky, he gasped when he saw something quite unexpected; a large planet that appeared to be similar to Saturn, though it more of a bright blue-green color and the rings were less pronounced.
"What? This is not normal," said Harry in a very confused tone.
Harry could only stand there as the realization dawned that somehow he had teleported himself to another planet in an entirely different solar system. Though given the gas giant in the night sky, a large moon seemed like a more accurate description of the world he was now on. He didn't know how this had happened but ruled out accidental apparition given the obviously extreme distance he had just travelled.
Harry was brought out of his thoughts as he once again heard strange whispering in the distance. He listened for a moment as the whispering continued until he eventually determined which direction it was coming from. He held his wand in that direction defensively as he slowly walked toward the source of the whispering.
While it was still dark, he was able to make out what appeared to be a large lake, which gave a very impressive reflection of the planet in the night sky. Whatever was speaking, it was obviously in the water. Harry kept his wand ready as he walked up to the edge of the water. Listening carefully he was finally able to discern what the unknown voice was saying.
{So, do you think you would like fish today?}
{Sure, fish works,} replied the same voice strangely.
{Is someone out there?} hissed Harry in Parseltongue, though he believed that he was speaking English.
The strange voice had stopped the moment Harry had spoken. After a few moments, he finally noticed something approaching in the water. Moments later, a most unusual creature emerged from the water and was looking directly at him. The creature appeared to be snake-like with four jaws, aquatic fins and a few other odd features. He deduced that this creature was native to this world and, judging from the fact it could talk, could be intelligent. The young wizard decided that introductions were in order.
{Hello, my name is Harry Potter. What's yours?}
The serpentine-like creature responded, {My name is Einar.}
Harry nodded and looked around at the water for a moment before turning back towards Einar. {Is there anyone else here?}
Einar shook his head as he replied, {Only Einar, no one else.}
{Oh, I'm see. You must really miss your family then...} Harry paused when the creature gave an agitated hiss. {I'm sorry, did I do something wrong?}
{My family believed Einar was eaten by big bad fish and had gone through the Chappa'ai without him a long time ago. Einar has been alone ever since.} Einar paused for a moment, then continued, {How is it that you are able to speak let alone understand the natural tongue of the Goa'uld? That is supposed to be physically impossible for humanoids.}
Harry just looked at the serpentine-like alien creature with a confused look on his face. He could've sworn that he was speaking English and yet Einar was claiming that he was speaking an entirely different language.
Before Harry could think on this more, he felt a sudden overwhelming wave of dizziness hit him as he began to succumb to the injuries he sustained when Vernon beat him up. The young wizard's wand slipped from his hand as he collapsed to the ground by the edge of the water. As Harry lost consciousness, he heard Einar calling his name with a tone of concern in his voice.

Hogwarts School of Witchcraft and Wizardry, Scotland, United Kingdom, Earth
Albus Dumbledore, the Hogwarts headmaster, was sitting in his office in deep thought. It has been an hour since he lost track of Harry Potter.
A short while ago when Dumbledore was meeting with the house heads, a clumsy owl called Errol showed up in the office and crash landed on the desk. Unfortunately for Professor Severus Snape, the owl accidentally knocked over the nearby container of magical Liquorice Snaps and spilled the contents all over him; needless to say the poor head of Slytherin House needed to be taken to the hospital wing with numerous bites covering his face and arms.
The owl had delivered a letter from Molly Weasley. Apparently Ron, Fred and George had flown their father's enchanted car to Surrey and back last night with the intention of rescuing Harry from the Dursleys. According to the boys, it was like Harry had apparently disapparated in a bout of accidental magic triggered out of fear. However, that seemed highly unlikely since Harry had the underage Trace on him and yet Dumbledore was still unable to find him anywhere. It was like he fell off the face of the Earth.
Little did the elderly professor know that is exactly what happened.
