Harry's P.O.V.
I sighed as I made my way to Care of Magical Creatures. I was the only one in Gryffindor to continue Hagrid's class. In fact, I was the only student in his class. Everyone was terrified of his class, and him. Even my best friends, Ron and Hermione, told me I was nutters. But one of the positives of being the only one to continue Hagrid's class was that it gave me time to be alone and think about all stuff that had happened since the final battle. I sighed; it was stupid to think of such things. What was done was done, and that was it. As I approached Hagrid's hut I noticed something was off. Instead of standing outside waiting for me like he always was, he was nowhere to be seen. I sighed and started walking over to his cabin when I heard coughing in the forest and Fang barking. Glancing around again quickly to make sure Hagrid hadn't appeared suddenly, I ran off in the general direction of the sound.

It wasn't long before I found the source of the coughing; instead of Hagrid, there was a man with long blonde haired, doubled over just inside the tree line. I ran up to him and caught him just as he fell. He looked up at me. His face scrunched up in pain, his beautiful blue eyes were glazed over. Fang came up and started licking me. I conjured up a piece of parchment and a quill, and scribbling a quick note, I stuck it in Fang's collar and told him to find Hagrid. Once Fang had run off, I looked over the man. His unusual clothing was torn and dirty, stained with blood in places from several deep gashes and a stab wound to his stomach. I pulled out my wand and started to heal him the best I could; it was lucky Hermione had insisted that we learn some basic healing charms during the war.

"I need you to relax so I it won't cause to much pain when I perform this spell." I said to him. He nodded and closed his eyes, taking ragged, deep breaths. I quickly did the stitching spell as fast and as best I could. I could hear people running towards us. I ignored them and continued to heal him. I searched through my bag and found the Sleep Drought I was supposed to give to Uncle Snape. He won't mind when he knows why I thought as I uncorked it and raised his head slightly. "Drink this. It will help you sleep." I told him. He nodded, and I helped him drink the liquid. He smiled gratefully at me, and fell asleep just as Hagrid, Snape and Madam Pomfrey reached us.

"Harry, are you alright? Who is this man? Are you hurt?" Snape asked in rapid succession, not giving me the chance to answer. Snape was my other godfather, and once you got to know him, he was a very caring man. I raised my hand, which stopped his flow of questions.

"Yes, I am alright. I'm not sure who he is, but he's hurt quite badly." I looked back down at him, and noticed that he had pointed ears and he seemed very familiar. His name, I know from somewhere. Then it hit me. "He's an elf, though obviously not a house-elf. His name is Legolas. That is all I know. He was injured when I found him. Fang was barking at him. Madam Pomfrey needs to check him over. I've done the best I can, and given him a Sleep Drought." I explained, and looking back over my shoulder, I saw Hagrid and Madam Pomfrey. "I would like to go with him, if you don't mind Hagrid. I am the only person he's seen so far, and he might panic if he's surrounded by a whole bunch of people he doesn't know when he wakes up again." I said, and he nodded and picked up Legolas carefully, leading the way to the castle.

"Put him here Hagrid." Madam Pomfrey said, gesturing to a bed in the far corner. "Harry, would you mind fetching the Headmistress?" I nodded, and ran out of the Infirmary. It wasn't long until I found Professor McGonagall, and with a quick explanation, we returned to the Infirmary, where Madam Pomfrey was healing Legolas.

"Good morning Poppy." McGonagall said, walking over to the bed that Legolas was in. "How is he going?"

"Quite well. Just a few gashes and a small amount of bruising. His stab to the stomach was the worst, but Harry's done a very good job. He'll be right as rain soon." McGonagall nodded.

"Do we know where he came from?" Madam Pomfrey shook her head.

"Harry just said his name was Legolas, and he's an elf. As far as I know, house-elves are the only kind of elf in the wizarding world." I sat down in the chair beside Legolas' bed, only half listening to their conversation. My mind was overwhelmed; how did I know his name? I'd never met him, nor any elf, in my entire life. I must of drifted off at sometime, because next thing I knew, I was being called down from my place in my favourite tree by Arwen.

"Marcaunon? Where are you? I know your upset with Ada right now, but the King of Mirkwood and his son have just arrived, and Ada requests you come welcome them." With a huff, I jumped down from my branch, landing beside her lightly.

"Fine. Let us go." I said, and she took my hand and led me back to the palace. Entering the Entrance Hall, we took our places beside Ada, waiting for King Thranduil and his son, Legolas, to enter. The door was pushed open, and the entered. The breath left my lungs; he was beautiful, with long, blonde hair and shining blue eyes, framed by thick lashes. He was the spitting image of his father, who strode forward with a confident stride, silver crowning his head. Just as we were about to speak, I jolted in shock when I realised someone was shaking my shoulder. I looked around, my sight a little hazy. I calmed down once I realized where I was. My vision cleared slowly and I saw Legolas looking at me in worry.

"Are you alright mellon nin?" Legolas asked me, I cocked my head hearing the familiar words.

"Yeah, I'm fine. Stuff like what just what just happened it normal for me." I told him, he stared at me for a moment then nodded. "Um.. do you think you could tell me what happened to you? I mean, so you don't get interrogated by the Headmistress and Professor Snape." I explained to him, he nodded.

"I was preparing for my trip to Rivendell when I saw an Orc. Myself and the guards followed them, and we came across a rather large group of Orcs, who must have been heading to Orthanc. We fought and I was stabbed in the abdomen. Then the next thing I knew, I felt like I was falling and I landed in that forest, and the dog started barking at me and then you showed up and that's all I remember." He said. I nodded and propped his pillows up so he could sit up properly.

"My name is Harrison Potter, but I prefer Harry, if you don't mind. You are at Hogwarts School of Witchcraft and Wizardry. I'm a student and this is my final year. I'm sorry, but you might be asked a lot of questions and people might not be very trustworthy of you because we just ended a 20 year war. So in advanced, on behalf of Hogwarts, I'm sorry for the way people will act. I know you're not a bad person, because you would have attacked me already if you were." I said, and he nodded in understanding.

"I understand. My own world is in a war. I am Prince Legolas of Mirkwood, in Middle-earth. Thank you for you hospitality, but I must get back to my own world; I am needed there." Luckily, I knew just the people to get Legolas back to his own world.

"There is a group of people here who are sort of a secret group that can help. Also, I can talk to my godfather, Professor Snape. Just give me a minute, and I'll have them come up here before dinner starts." I said, taking out my fake galleon that Hermione has made in fifth year (a modified and better version of course) and started to play with the numbers. It told them where to be, what time to be there, and why. I sent a special one to Hermione to get Professor Snape. It wasn't long before I got several 'okays'. It was then that my stomach decided to grumble loudly, causing me to flush in embarrassment. "Sorry about that, I skipped breakfast and lunch. Kreacher! Dobby! Winky!" I called out. The three house-elves appeared before us with a crack, big tennis ball eyes blinking innocently. Legolas jumped in shock.

"What does Master Potter need?" Kreacher asked.

"What do you need Harry Potter, sir?" Winky said, curtseying.

"What does Harry need?" Dobby asked me. I smiled and looked at Legolas. "Guys, I'd like you to meet Legolas. Winky, do you think you can go inform Professor McGonagall that our guest has awaken? And please, just call me Harry." I told her. She nodded, and with a crack, disappeared. "Dobby, I need you to go down to the library and get me at least two books that explain dimensional traveling and Magical races." He nodded and hugged me around the neck before rushing off. I turned back to Legolas. "Do you eat meat?" He shook his head. "Kreacher, could you please get us some food, no meat, some butterbeer and water?" he bowed. "Oh, and some treacle tart!" I added quickly, just before he apperated away. Hopefully he heard me.

"May I ask who those creatures were?" Legolas said, his voice calm though his eyes showed surprise. This simple question lead me to spending the next three or so hours explaining the wizarding world. "Thank you Harry." When I had finished my explanation. "I am a fool. My race is so prejudiced against others because we live forever. Even though you are different, you treat all living things the same." He told me. I simply smiled, and poured him some more water. He emptied the cup just as McGonagall came in.

"If Potter trusts you Legolas, it gives me every reason to as well. Potter always has had a good sense of self preservation." she said once she reached the bed. "McGonagall, Headmistress of Hogwarts." She said, extending her hand for him to shake. He smiled gently.

"Prince Legolas of Mirkwood, in Middle-earth." he said, taking her hand. At that moment, Dobby apperated back in with several very large books.

"Thank you Dobby." I said, taking the books from him, and setting them on the desk. "That is all we need." Dobby nodded and disappeared again.

"I have all your homework here Potter." McGonagall said, pulling a neatly folded piece of parchment from her robes. "The Professor don't expect it to be completed but they want a start on it." With that, she nodded and left us again. Tucking it into my jeans pocket, I handed Legolas a book, and we began to read. I found very little information about inter-dimensional travel in the first book, only being able to take a few notes. I gave a quill, ink, and parchment to Legolas so he could also take notes. As I began to read the next book, something about what it was telling me seemed familiar. I took down several notes from that page, and moved onto the next. About half way down, one paragraph caught my attention.

"Several years ago, a young elf landed in this world through inter-dimensional traveling. When we found him, his ears were pointed, he had long black hair, and large, startling green eyes. We asked him how old he was, and he replied in a strange language. We figured out he was 800 years old, and then right before our eyes, he turned into a human child, only several years old, with the same black hair, now short and messy, the same startling green eyes, and a lightning bolt scar. He is now more commonly known as the-boy-who-lived. Nobody knows of the boy's origins, or that his real name is Marcaunon. The Ministry of Magic banned us from saying anything, so we wrote it down. We hope whoever reads this will be able to solve this mystery." With that, the paragraph finished.

I am from a different dimension. I thought. Just my luck.

"Legolas, has anyone gone missing from your world. I just read a paragraph in this book that said an elven child appeared in this word. He had long black and big, startling green eyes. It says his name is Marcaunon?" I asked him, hoping he would know. A pained look crossed his beautiful features and his eyes held distant memories in them.

"Yes, Marcaunon did disappear. He would be 1,800 years old now, for today is his birthday. I am 3 years older than him. We used to sing the song of Nimrodel together." And he began to sing in a beautiful voice

An Elven-maid there was of old,
A shining star by day:
Her mantle white was hemmed with gold,
Her shoes of silver-grey.

A star was bound upon her brows,
A loght was on her hair
As sun upon the golden boughs
In Lórien the fair.

Her hair was long, her limbs were white,
And fair she was and free;
And in the wind she went as light
As leaf of linden-tree.

Beside the falls of Nimrodel,
By water clear and cool,
Her voice as falling silver fell
Into the shining pool.

Where now she wanders none can tell,
In sunlight or in shade;
For lost of yore was Nimrodel

And in the mountains strayed.

The lyrics then came to me, and I joined him in the rest.

The elven-ship in haven grey
Beneath the mountain-lee
Awaited her for many a day
Beside the roaring sea.

A wind by night in Northern lands
Arose, and loud it cried,
And drove the ship from elven-strands
Across the streaming tide.

When dawn came dim the land was lost,
The mountains sinking grey
Beyond the heaving waves that tossed
Their plumes of blinding spray.

Amroth beheld the fading shore
Now low beyond the swell,
And cursed the faithless ship that bore
Him far from Nimrodel.

Of old he was an Elven-king,
A lord of tree and glen,
When golden were the boughs in spring
In fair Lothlórien.

From helm to sea they saw him leap,
As arrow from the string,
And dive into water deep,
As mew upon the wing.

The wind was in his flowing hair,
The foam about him shone;
Afar they saw him strong and fair
Go riding like a swan.

But from the West has come no word,
And on the Hither Shore
No tidings Elven-folk have heard
Of Amroth evermore.

When we finished, he stared at me for a minute before smiling, a brilliant smile that reached his eyes. "It's been a while." I said, rubbing the back of my neck. "How I've missed you Legolas."
