LOTR Boarding school
"A New Year is now upon us and I expect you to make new friendships and meet old friends and HOPEFULLY finally join my army of orcs in destroying all of middle ear… I mean making the world a better place (snigger) (whispers) yeah like that going to happen"

With that the headmaster finished his speech and walked off.

"Hey Aragorn" whispered Legolas "Any idea who is in what rooms?"

"I don't know" replied Aragorn "hey wait there handing the room plan out"

Legolas went over and took a few and handed them out to the rest of the gang.

"Hey cool it looks like they have finally realised we hate those geeks" Haldir said.

The rooms were as follows:
"Room plan 2004
Room 1:
Frodo
Sam
Room 2:
merry
Pippin
Room 3:
Denethor
Eowyn
Room 4:
Gollum
Grima
Room 5:
Me you and Faramir
Room 6:
Eomer
Haldir
Boromir
Vanimawen"

"Cool" Aragorn butted in "we've got the larger rooms"

"Only one new person" Said Haldir pointing to Room 6

"More will come" Aragorn replied "they always leave new people out of the plan and place them in rooms randomly

Legolas continued
"Room 7:
Arwen
Elladan
Elrohir
Room 8:
Glorfindel
Gimli
Gamling"

"Finally we aren't with any nerds and we are together" Boromir said.

Everyone left the Hall and went to there rooms except Aragorn and Legolas who stayed behind to wait for Faramir who needed to speak to Theoden about him not being able to do horse riding as he had sprained his ankle while chasing Haldir who had taken his bag and he had slipped and fallen down the stairs.

Aragorn knew that it was a fake injury but supported his friend. Theoden saw through the trick but as he didn't like Faramir much decided to play along and sent him off to Gandalf for medical attention (Faramir hated Gandalf)

Aragorn and Legolas therefore went off to Room 3 and unpacked their stuff.
Aragorn chose the bed nearest the window and the desk that had a pencil holder and a built in dictionary (he defiantly needed it). Legolas let him take the best stuff and chose a Bed and a desk identical to Aragorn's minus the dictionary. He then finished unpacking and went off to the library and bought back a book called "The Silmarrilion" It was about Elves and jewels and creation of Middle-Earth.

Aragorn stood back up after picking up a dropped book and sighed "Legolas, why do you always READ?"

Legolas looked up at him and closed the book and put it on the shelf that was next to his bed. He then took Faramir's bag, which he had given to Legolas. Legolas unpacked everything in it before he found a diary. "Hey Aragorn look at this"

Aragorn came over and laughed at what Legolas had found. They began to read even though Aragorn had a bit of difficulty, his father hadn't put much effort into his education.

It read:
Dear diary,
I've only started you and this is my 1st entry. I might as well write some stuff about my friends and me.
Eomer:
Cool, kind, not very active Haldir:
Blond haired, v.good guy quite nice Elf Boromir:
My older brother enough said Aragorn:
Best mate. Cool strong but not very bright Legolas:
Strange, not like the others smart and shy great archer though Eowyn
"Eowyn!" Exclaimed Aragorn shocked.
"They have been together for a while, he told me." Legolas said
Just then the door flew open and Faramir stormed in, Legolas quickly hid the book.
"WHO TOUCHED MY STUFF!" Faramir yelled, glaring accusingly at Aragorn and Legolas.
"Calm down mate I was only trying to help!" Legolas retorted.
"FINE" He yelled and stormed out.
"Touchy" Aragorn said.

Haldir walked in through the door, that Faramir had left open.
"What's wrong with him?" He said in his ever-calm demeanour.
"Dunno he had to go to Gandalf" Aragorn said.
"oh well" said Haldir "anyways, wanna go down to the archery range?"
"Legolas and Aragorn jumped to the idea, they quickly fetched their bows and went down to the Archery range . After a while of shooting the targets, Haldir got bored and went to fetch some drinks while Aragorn went off to his and Legolas's room to fetch his arrow mending kit as most of his arrows had broken, due to ill care and he refused to use Legolas's kit. This left Legolas alone.

He slowly walked down and collected his arrows before, while he was pulling his arrows out he heard a sudden twang of a bow string and moments later the arrow he was pulling out was shot through with another, finely crafted shaft. Before he could fully register this information another arrow pierced his tunic and pined him to the target. He heard a soft tinkering laugh.
"Wow" He gasped turning to his assailant expecting one of the twins or Haldir to be standing there, but no it wasn't it was an elf for sure, but none like that he had ever met.
"Hello" She said "my name is Vanimawen"
