The Unbreakable Oath

Lily was your typical teenage girl. She liked chocolate, clothes, make-up, and partying. She had a best friend named Alexis and she was currently a guy. Yeah, that's right. Lily Evans was now a guy. It had started a week ago when she and Alexis were goofing around in Alexis's basement. They were both witches but Alexis was pureblood. They both had attended Avalon. It was named for the mystical land of the Lady. If witches were anything they were pagans. It was an all-girls school and the most advanced school in Europe. Even Hogwarts couldn't compare. So anyway Alexis and Lily had been goofing around. Alexis had suggested fire whiskey and Lily had agreed. An hour later they had been so drunk it was a miracle that they could stand. Then Lily had chipped a nail and told Alexis. Alexis had mocked her and Lily had defended herself. One thing had led to another until Alexis bet that Lily couldn't go one school year disguised as a guy. Lily, in her fully drunken state, had taken the bet. She said that she would even take the Unbreakable Oath that she could do it. Alexis, in an even more drunken state, had agreed. Lily had taken the oath then promptly passed out. Alexis followed only minutes later.

"Aaaaaaaaahhhhhhh!" Lily screamed when she woke up the next day. She started shaking Alexis. "We didn't." She repeated over and over again, like repeating it would make it not true.

Alexis sat up rubbing her eyes. "What are you talking about?" She asked. Then it dawned on her and a lock of shock struck her face. "I'm so sorry Lily." She said. She leaned over and gave her a huge hug. I didn't mean to. I'm sorry. I'm sorry."

"I'm going to die." Lily didn't exactly cope well with stress.

"No you aren't." Alexis insisted. "We can disguise you as a guy and fool everyone. It'll work." She tried to sound confident. "Now lets discuss this over some aspirin." She stood up and wobbled.

"I'm gonna die. I'm gonna die. I'm gonna die." Lily repeated following her. Fifteen minutes, 6 aspirin each, a three cups of coffee later Lily was coping slightly better. Emphasis on slightly. "I might die. I might die. I might die."

"Lily calm down and shut up." Lily stopped talking merely out of shock. "We can do something about this. First things first, what school do you want to go to?"

"What?" Lily asked panicked. Apparently she had forgotten that Avalon was an all girls school.

"You can't go to Avalon. It's an all girls school. So what school do you want to go to? I personally suggest Hogwarts. It's the best school next to ours and it allows guys and girls." Alexis was the one who coped well under pressure. Last night was one of the only times she had ever done anything wrong. She had done it because her parents weren't going to be able to come home before school started. They were always working and they never had time for Alexis. So she had wanted to blow off some steam. How she regretted it now.

"Hogwarts it is." Lily said, slightly calmer. She was grabbing her head trying to get it to stop hurting from the hangover. Even in the wizarding world there was no way to recover except time and aspirin. "Can we talk about this when the hangover goes away. For now I want pancakes."

"Okay." Alexis said getting up to make them. Until this year was up Alexis was going to be Lily's slave. She felt so guilty.

Three hours later they were both recovered and were sitting on Alexis's bed. "So the whole guy thing. How is that going to work." Alexis asked Lily.

"I'm guessing that once the school year starts I have to change into a guy's body and no one that doesn't already know can find out unless I tell them. So I have to fool everyone." Lily guessed.

"Do you know the charm?" Alexis asked.

"If there is one thing I know it is the charm." Lily snapped. She had always been the one who was perfect in transfiguration and charms. Alexis only beat her in potions.

"Sorry I asked." Alexis was only slightly offended. "Do you want me to pretend to be a guy too?"

"No." Lily refused the offer. "It will just make it harder. Besides you have to cover for me. Convince my parents that I still go to the Avalon. I really don't want to have to explain this to them."

"Well, good luck." Alexis was at a loss for words. "Write me often."

So that was what had happened. That had been additional planning but on September first Lily was standing on Platform 9 ¾. She was now 6' 1'' and 220 pounds. Her hair was sandy blond, she had refused to stay red headed, and her eyes remained green. Her trunk was full of guys clothes and her voice had been changed. She thought she was ready. If not, well, only her life depended on it. She stepped through the archway, ready to be a guy. "Oof." She said, immediately crashing into someone. He just kept walking, not even noticing Lily. She glared at him as he walked away. He was 6' 2'', only slightly taller then Lily's recently acquired height. His raven black hair was so tousled that it looked like he had just gotten off a broom stick. Since Lily was looking at his back that was all she could notice. "Jerk." She muttered under her breath. She looker around at all the people. She instantaneously started hating Alexis. And fire whiskey. Mostly Alexis, though.

"Who's a jerk?" A voice said next to her. Lily turned to look at him. "I'm Thom Cerdic." He said, holding out his hand.

Lily took his hand, panicking inside her head. I never thought of a name. I need a name. Er.' "Harry, Harry Evans." Her last name she supposed was safe to use. No one here had any reason to have heard of it.

"Nice to meet you. Now who's the jerk?" Thom asked again. Lily pointed to the retreating figure of the guy. "You mean James Potter?"

"I guess." Lily answered.

"Take care not to say that again." Thom warned her.

"Why?" Lily was curious now.

"Because he is king of Hogwarts. Well co-king really." He amended himself. "Between him and Sirius Black the Marauders are worshipped and feared. No one dares to cross them."

"Why?" Lily scoffed. "Are the two of them going to run me out of the school."

"Four." Thom corrected her. "Remus and Peter as well. And no. But they will prank you until you wish you were out of the school. By now all of the Slytherins are feeling that way."

"Slytherins?" Lily asked confused.

"One of the four houses. Someone will explain it to you later. Where did you transfer from anyway?"

"Avalon." Lily answered automatically. Thom's face showed a look of confusion. "I mean," Lily stuttered, "A school next to Avalon. It was called Gwent."

"Never heard of it." Thom replied. "Anyway you better get on the train. It's about to leave." With that he turned around and walked over to his friends, leaving Lily there alone. She looked around, once again and then hopped on the train. She wandered down the aisles looking for a compartment in which to sit. She had to remind herself not to sit with the girls. All of the compartments were full, save one by the end. It had only two boys in it. She asked if she could sit down and the taller one said she could.

"I'm Sirius Black." He introduced himself. "That's Peter." He said, jerking his head to indicate the guy across from him. He waved and it was at that moment Lily realized her mistake.

"You're the Marauders." She said.

"Yeah." Sirius seemed surprised. "You've heard of us already. Peter I think we're famous." At that moment the door slid open again and another boy stepped in. It was the same boy that Lily had crashed into earlier. "Oi! James, we're famous. This guy has already heard of us. Who are you anyway?" Sirius asked, turning back to Lily.

"Harry Evans." She answered, using her alias from earlier. "I transferred from Gwent. My family got into a fight with the Headmaster." She stopped her explanation there, not wanting to make it more complicated then necessary.

"James Potter." James introduced himself before sitting down next to Peter. "Remus will be here in a minute." He was addressing Sirius now, "He has Head duties."

"I just hope he doesn't try to put us in detention." Sirius replied. He and James laughed at that.

"So how have you heard of us?" James turned back to look at Lily. It was then she noticed his looks. If only she was a girl. She would have dated him in a second. As it was…

"Someone named Thom told me about you." Lily replied.

"Cerdic?" Sirius questioned. Lily nodded her head.

"He doesn't like us so don't listen to what he told you. We aren't quite that bad." Sirius explained. "Unless you're in Slytherin. 'Cause then you will hate us even more."

"Slytherin?" Lily asked a second time.

This time she got an answer. Peter explained about the houses but when he reached the point about quidditch James jumped in. "So what position do you play?" He asked excitedly. "I need a seeker and no one I know looks very promising."

"He's captain and chaser of the Gryffindor team." Sirius put in.

"Sorry to disappoint you but I am a chaser, and not a very good one." Lily answered. In truth she had been captain of her old team and so was probably just as good as any of them, if not better. James's face fell. He then started talking about the World Cup. It had been hosted in Germany but his parents had taken him and Sirius to go see it. Lily had just heard about it but she joined in the conversation. She was all for Germany while the Marauders supported Ireland. Remus walked in ten minutes later and also joined the conversation. It lasted them all the way to Hogwarts.

Half-way through the tea trolley had come and James had bought a mountain of food. Lily had offered to buy her own but he had refused. None of the other three had even offered so Lily assumed it was a regular occurrence. The guys had inhaled their food while Lily ate daintily. "You eat like a girl." Sirius insulted her, or at least to his knowledge he did.

"I have a lot of sister." Lily had tried to brush it off. She had then tried to force herself to eat like them, but couldn't quite manage. She had then changed the subject back to quidditch, but was still panicked.

When they arrived at Hogwarts Lily followed the Marauders out of the train. She took a glance at the horseless carriages. "Threstrals?" She guessed.

"Yeah." Remus answered. "How did you know? Can you see them?"

"No. Just read about them." Lily replied. Remus jumped into the carriage after Sirius.

"Sorry Harry." James said. "There's only enough room for four." With that he followed Remus. Lily looked around and saw that all of the carriages were full except for one.

"Come here." A girl waved at the remaining carriage. Lily walked over and jumped into her carriage. "I'm Ceren. This is Aurora and Gwen." Ceren introduced them. When she was waving her hand Lily noticed her hand. Ceren had a French manicure with little dolphin stickers.

"I'm Li-Harry." Lily introduced herself. "I love your nails." After that comment Lily mentally smacked herself. She had let herself slip up twice. She had to be more careful.

"Thanks." Ceren said. "You're the first guy to notice them."

"I have a lot of sisters and they trained me to notice things like that." Lily offered the same, sad excuse again.

"I like that." Ceren said, smiling. She leaned closer to Lily. Lily almost gagged. Ceren was flirting with her. This was disgusting. But of course Ceren didn't know that she was a girl. Still. Lily hater Alexis.

For the rest of the trip Lily remained silent. Finally Ceren gave up and started talking to her friends. Lily almost jumped in a few times, but then she remembered that she was a guy. Finally it ended. Lily was the first one out and she sighed with relief. She waved good-bye to the girls and was immediately attacked by the Marauders. "I wish I was you." Sirius groaned. "How did you do it?"

"Do what?" Lily was oblivious.

"Get Ceren, the ice queen, to talk to you." Remus answered, in a matter of fact voice.

"I just complimented her nails." Lily answered like it was obvious.

"Are you sure that you aren't a girl?" James asked.

"I'm positive. Why would you think that?" Lily fretted. James frowned but didn't say anything else. Lily sighed in her head.

"You should go talk to Professor McGonagall." Remus said, pointing to a strict looking lady. "She'll get you sorted."

"Thanks," Lily said, walking towards the professor. "Excuse me. I need to know which house I'm in." Lily said, once she got to the professor. "I just transferred here."

"Follow me." The professor said curtly. Lily followed her into a office. "Since your not a first year I'll sort you privately in here." Lily was filled with instant gratitude. She picked up the hat, that Lily knew from Peter's explanation was the Sorting Hat, and put it on Lily's head.

So you're a girl. Huh. Lily panicked. Don't worry. I won't tell anyone. But that takes courage. But you also have cunning. And skill, I see a lot of it. Ravenclaw maybe. Or Gryffindor? Gryffindor, Lily thought. I want to be in Gryffindor. Then Gryffindor it shall be. It split open it's mouth and said it so that the professor could hear.

"Welcome to my house. I trust you will uphold it's honor." McGonagall said.

"Wait, it's your house." Lily said, clearly shocked.

"Why? Do you want to switch houses?"

"No Ma'am." Lily answered. "But Peter made you sound so much scarier."

"Well to him I probably am." The professor said. "Go to your house table now."

Lily gladly obliged. She sat down next to James. "Congratulations." He whispered. Then he pointed at the main table where the Sorting Hat was in front of. It opened it's mouth and began to sing.
