I'm so sorry! There's been these tests and a new subject in school! And all these field trips! I know it took me forever but I'm writing now. I'll never take this long again.

Disclaimer: I do not own HP. Straight to the fic.

Beautiful moonlight, yet evil

The next day Remus looked extremely pale. It was almost 6:00 O'clock. His hand was shaking as he tried to write more of his essay.

Meanwhile, Sirius was paging through his defense against the dark arts book. They hadn't even opened them in class yet. 'That teacher has no business teaching here,' Sirius thought. He suddenly stopped as a picture caught is eye. He looked at it.

The thing was huge. It was a brownish grayish color and its fur was thick. Two-inch fangs glistened in the light of a full moon, as the monsters tongue hung out of its mouth. It had great yellow eyes that seemed to penetrate the soul. Sirius shuddered and read the caption.

Of the many fearsome beasts in this world, one of the most deadly is the werewolf. These monsters transform from humans to the werewolf in the light of the full moon, which occurs once a month. At bite will cause a human to become a werewolf, though werewolf's aim to kill. The werewolf will take over the human on full moon and crave blood.

Sirius looked once more at the picture before closing his textbook. He looked over at Remus's shaking form, and saw James looking too. Their eyes met a second before looking at Remus.

"I got to go you guys. My mum is sick again." Remus stood up and walked out of the common room.

Sirius sat up straighter in his chair and turned around to look at the clock as it struck six. It was just getting dark and the full moon would be out soon.

Full moon?

Now that he thought about it, Remus always left on the night of a full moon, coming back scratched and bruised. When they had asked Remus what had happened he had snapped his cat had scratched him.

The subject hadn't been brought up again.

Sirius suddenly got an idea. It was so abnormal, such a creepy idea that he fell of his chair on to the floor.

"Ow."

James looked at him oddly as Sirius tried to get of his head and stand up. That proved difficult for the fact that a table was in front of him so he couldn't move his legs down.

James watched Sirius struggle to get upright with an amused look on his face. When Sirius finally emerged (from under the table) he had a flustered look on his face. He made to get up but hit his head on the table, not realizing he was still under it.

"Ow! Bloody hell!" he yelled. Some second years near him looked at him strangely.

James held in a chuckle. "Alright there mate?"

Sirius lay on the floor with his hand on his head. He looked up to see a bemused look on his friends face and glared. "Yes. Don't see what's so funny though."

James considered him. Sirius was laying half under a table, with his feet still by the chair. He had a hand on his head and his hair was flying in a whole bunch of different directions. One of his shoes had fallen off and was now sitting innocently next to the chair. Sirius moved his foot and it fell. He tried to pull himself out from under the table and almost knocked it over, when a cup of water fell off the table and landed on his head.

James tried not to but couldn't help it. He burst out laughing. Sirius glared at him. "Mind helping me?" he asked.

James shook his head, still laughing. Sirius tried to move but found his foot stuck underneath the chair. James finally took pity on him and helped him out from under the table. "Wait until I tell Remus this!" he said.

Remus! Sirius suddenly remembered why all that had happened in the first place. He looked at the clock and saw it was 6:30.

"James, I think I figured out where Remus goes every month," Sirius said.

"Yeah to visit his sick mum," James said.

"No. I think he's a...." Sirius stopped and looked around the room. "Werewolf," he whispered.

James looked at him with a shocked expression. "Remus? A...a werewolf? No way." Not kind, gentle Remus. He could never be a blood-seeking monster.

Sirius began explaining his theories. "And he's gone like every night of the full moon! Don't you see James? It makes perfect sense!"

James didn't look completely convinced. "I don't know Sirius."

"Let's follow him next month," Sirius said. "Let's follow him and see where he goes."

James sighed but nodded. He knew there was no way to talk him out of it.

During the month nothing overly large happened. They played a few small pranks one which included Snape's bed being filled with snakes. ("He deserves it, his houses symbol is a snake" Sirius had said.) Soon it was the night of the full moon. James held his invisibility cloak (he had only just got it) under a chair. At Six Remus left, and Peter went up to the dormitories.

"It's now or never," Sirius muttered.

James and Sirius quietly walked out of the common room. They slipped on the cloak and followed their friend.

.....................

Sirius and James had been quite surprised when they found out how to get past the willow. They had shared a look of confusion but had followed all the same. They were now walking down the path. Remus was far ahead of them, as he was running. Sirius and James, not use to the tunnel, kept tripping. They agreed to take of the invisibility cloak and walked quicker to catch up with Remus.

After walking a little ways, they saw stairs. They looked at each other and began walking up them. Sirius, slightly taller, hit his head on a trap door. (I can't remember if there was one of not. If there isn't, I just think this makes more sense so that Remus couldn't leave when he transformed unless he had help.) The two friends looked at each other before pushing open the door and climbing into the shack.

They didn't know where they were at the moment, but it didn't look good. There was dried blood on the floor that seemed to blend in perfectly. Furnisher around the room was torn and ripped apart. Upstairs, they heard the shrieking of their friend.

Sirius and James looked at each other before walking up the stairs.

Sirius was the first to react to the site that reached them.

He couldn't believe his eyes. In front of him was the same creature, the same creature he had seen in his Defense Against The Dark Arts book when he was skimming it. The long shaggy fur, the deep white fangs. He was rooted to the spot with fear.

Why had they followed that passageway? He should have known something bad would be happening if his friend hadn't told him about it. This was bad. This was terrible.

The two boys stood in the monsters wake, it licking its lips (or fangs, whichever you prefer) as it smelt the blood.

'Blood, I can smell it! I need it! I must taste it!' the monster thought, staring at the pale boys faces. 'I will get blood tonight.'

James and Sirius were frozen in fear. They couldn't move a muscle. They just stared into the werewolf's yellow eyes. How could this monster be their quiet friend Remus Lupin?

The werewolf began to slowly walk toward them. Sirius decided to try his luck, as he saw no way to escape. "Remus. It's us. Your friends. Sirius Black and James Potter. Surely you remember?"

The werewolf snarled and pounced. He landed on top of James, his claws digging into his flesh. James let out a gasp as crimson blood began to leak from his skin. The werewolf looked ready to bite, but stopped as it was hit in the head with a piece of wood.

"Stay away from him you!" Sirius shouted. The werewolf growled menacingly and jumped off of James and ran at Sirius. Sirius moved just before the werewolf bit him. James looked around franticly and spotted a door. He stood up; taking no notice of the blood falling from his arm and ran to the door, shouting for Sirius to follow him.

Sirius looked at where James was headed but stayed still a second to long as he felt the werewolf's claws swipe across his cheek. He clutched his face in pain; thankful he hadn't been hit in the eye, and moved before the werewolf bit him. He dodged into the room and James slammed the door behind him.

James, panting, slid down the door, taking no notice of the wood scraping his back. He looked at his arm and grimaced at how much blood there was. Him and Sirius jumped as the werewolf jumped against the door.

'Glad we left the invisibility cloak outside this place,' James thought as the werewolf jumped against the old door again. 'This isn't Remus. Remus is gone. He won't be back until the moon is gone.'

As the werewolf continued to try to knock the door over, Sirius sat down and leaned against the door. He wiped away some of the blood from his cheek with his robes, but more just replaced it. Him and James looked at each other.

"I'm glad he only managed to scratch us," Sirius said, knowing it wasn't just a small scratch. A drop of crimson blood dropped off his chin and landed on the dusty ground with a small plop.

James only nodded, also knowing it wasn't just a scratch. His arm hurt terribly, like it was burning. He knew if he didn't stop the blood flow he could suffer from loss of blood. He tore part of his cloak and wrapped it around his arm, not knowing what else to do to slow the blood.

There was another small plop as another drop of blood fell from Sirius's chin and landed on the floor by the first one. He sighed. They wouldn't be leaving anytime soon.

As night wore on, Sirius managed to fall asleep. There was a steady stream of plops as his blood fell to the floor. James applied pressure to his arm to slow the blood flow. He unwrapped his arm to see how fast the blood was flowing. He was relieved to see it was only bleeding a little now. He finally managed to fall asleep.

Preview:

Remus looked at the floor in shock. This wasn't his blood. He could tell that it wasn't. He looked around and noticed a closed door with huge scratch marks on it, and a small bit of cloth on the floor. He looked at it and recognized it as James.

He gasped and went to the door. He wasn't as hurt as usual, due to the fact (he was guessing) he had been busy trying to attack the student or students behind that door. He knew he only had a few minutes before someone would come to get him.

He slowly knocked on the door, scared of what would happen. The door opened and he gasped at the condition his two friends were in.
