A/N-This is definitely my longest chapter (nearly 5,000 words), and probably not all of them are going to be this long; enjoy!

Sorry for forgetting to put this in the last chapter!

Harry

As soon as they arrived in the common room, Thalia, Percy, and Nico slipped off to the side of the room and started an intense conversation. From what little he heard, Harry could tell that they were speaking Greek.

Ron shook his head. "They're great and all, but they act like a couple of nutters sometimes. What could they be saying that so important that they need to say it in Greek?"

"Well, they probably just don't want anyone listening in on them," Hermione said pointedly. "And we all know that you would try to."

"What did Professor McGonagall want to talk to you about?" Ron asked, changing the subject.

"Nothing interesting. Just some information about my classes this year." Hermione said breezily.

Harry could tell that she was hiding something, but Hermione was saved from further questioning when the three Americans finished their conversation and joined them by the fire.

"So, where do we sleep?" Percy asked. It seemed that the two things most often on Percy's mind were eating and sleeping. And he did quite a bit of both. Hermione showed Thalia up to the girls' dormitories while Harry and Ron headed up to the boys' room with Percy and Nico. There were two extra beds in the third year boy's room, with the names 'Perseus' and 'Nico' inscribed on the headboards. Neville Longbottom, Dean Thomas, and Seamus Finnegan were already in the room, and Harry hurried to introduce the two new additions to the room.

"Why did you three decide to come to Hogwarts? What was wrong with your American school?" Dean inquired.

"There wasn't anything wrong with it." Nico answered. "Our school presented the option of three students attending school abroad, and we were interested."

Dean seemed satisfied with the answer. "So, do you think you could 'introduce' me to your other friend?" He asked hopefully.

Nico and Percy tried to suppress their laughter. Percy failed. "Thalia doesn't date," Nico explained as Percy managed to quell his laughter.

"Well, maybe she just hasn't found the right guy yet," Dean said with determination.

Nico and Percy looked like they were about to be set off again. "I don't think she'll be convinced," Percy managed.

Dean was looking annoyed now. "Oh really? Well, I'll prove it! She'll be warmed up to me by the end of the year, you'll see!"

"I'll take that bet," Nico said with a smirk. "I put down twenty galleons that she won't be even remotely interested in anyone at all at the end of the year."

"You have that much?!" Ron asked in disbelief.

"Nope."

Dean looked at him incredulously. "Are you serious? You still want to do it?"

Nico nodded. "I'll even extend you're time limit for as long as I'm here."

Dean grinned. "Deal! Even if it isn't me, she'll be interested in someone eventually!"

"Are you sure you want to do that?" Harry asked Nico.

Nico smirked. "Trust me, there is no way that Thalia would ever be interested in anyone."

He and Percy changed into their night things, for some reason being extra sure that their curtains were closed tightly before undressing. Harry shrugged. Maybe the Americans were used to more privacy or something. After the day's excitement, Harry fell asleep quickly.

When Harry woke up the next morning, he found Nico already up and fully dressed, sitting on the edge of his bed. He threw a pillow at Ron, effectively rousing him, and they both pulled their robes and shoes on.

"We should probably wake up Percy," Harry commented.

Ron walked over to his bed. "Oi, Percy, wake up!" He continued yelling a series of similar phrases, but Percy didn't stir. Ron stepped back from the bed and scratched his head. "Well, I suppose we could try splashing water him."

Nico gave him an amused smile. "I don't think that would be very effective on him. He probably wouldn't even notice."

"Well, he's going to have to get up soon or he's going to miss breakfast-" Ron was interrupted as Percy shot up in bed.

"I'm up! Where's the food?"

"Well, now we know how to wake up Percy," Harry said with a grin.

Percy grinned sheepishly as he pulled on his black robes. They met Hermione and Thalia in the common room before heading down to the great hall for breakfast.

Percy, Nico and Thalia were quite startled at the owl post, making Harry think that their school must not have anything like it. A glance up to the head table showed that Professor Elric was having a similar reaction. He had turned to Madame Pomfrey, who was seated next to him, and was waving his arms and angrily saying something about crazy owls, but with much stronger language.

Harry received his schedule along with the others and looked it over. "Looks like we have Divination first, then Transfiguration, a break for lunch, Defense Against the Dark Arts, and then Alchemy. Looks like we're doubling with Slytherin in that one." Harry wrinkled his nose at the prospect.

"And I was really looking forward to Alchemy!" Ron groaned.

"Come on, it can't be that bad," Thalia said. "You should give the Slytherins a chance, I bet most of them aren't half as bad as you're making them out to be."

"Trust me, they are," Ron said.

Thalia frowned, thoroughly unconvinced, but before she could launch into another lecture about prejudice, Dean sauntered up to her with a charming smile on his face and a determined look in his eyes.

"Hello there, I don't believe I've had the pleasure. Dean Thomas." He held out his hand.

Thalia took it. "Thalia." She said evenly, still refusing to use her last name.

"Your name is as charming as your eyes," Dean said to her.

Thalia narrowed her eyes. "Let me stop you right there. Don't waste your time, I don't date."

Dean didn't falter one bit. "So I have been told. But I am confident that your mind will be swayed eventually! And then I expect your friend to pay his bet in full." He looked over at Nico with the last part.

Thalia whipped around to face Nico. "Are you using me for easy money, Death Breath?!"

Nico looked up innocently. "Why Thalia, I thought you knew me better than to ask that."

"Yeah Thalia," Percy chimed in, "you shouldn't have to ask to know that the answer is yes. Though you have to admit it's a pretty clever money making scheme."

Thalia looked ready to murder both of them with her toast and bacon. Harry decided he should intervene before she started turning breakfast entrees into deadly weapons.

"We should head to our first class. Do you three know where you're going?" Harry asked as he stood from the table.

Thalia stopped death-glaring at Percy and Nico. She hesitated a bit before answering, "Uh…yeah…about that…well, how to put this…we can't exactly…read our schedules very well…" she mumbled the last part, looking embarrassed. She held out three sheets of paper. "All three of us have really bad dyslexia. Would you mind…?" She didn't finish the sentence. Harry looked over at Nico and Percy, who were smiling apologetically. He must have stood there a second to long, because Hermione reached out and snatched the schedules from Thalia's hand.

"Of course we'll help you. Dyslexia isn't something that's your fault, after all," she said briskly, giving Harry and Ron a look. "There are plenty of people who have that problem, it's not like it's a rare disease or something." She scanned over the schedules. "It looks like you have the exact same class schedule as Ron and Harry. That's perfect, they can make sure you know where you're going. Hogwarts Castle is an easy place to get lost in, even if you've lived here for a long time." She handed back their schedules, and they thanked her profusely. "We should get going. Divination at the top of the North Tower, and it's going to take us a while to get there."

After a long trek through the castle and some directions from a slightly crazy knight, the group finally made it to the divinations tower, and just in time. They joined the rest of the students as a trapdoor opened in the ceiling and a silvery ladder dropped down. The Gryffindors glanced at each other skeptically. For some reason Thalia, Nico, and Percy looked exceptionally nervous. Nevertheless, they ascended into the attic along with everyone else.

The attic was dim, very warm, and heavily perfumed. Harry didn't see the teacher at first; the woman was sitting in the shadows. She had on large glasses that magnified her eyes, giving her an owlish look. As everyone found a seat around various tables spread around the room, she began to speak.

"Welcome, how nice to see you at last in the physical world." Her voice was misty and slightly detached, not holding any emotion. "Welcome to Divination. I am Professor Trelawney. Most of you most likely have not seen me before; I find that descending into the hustle and bustle of the school clouds my Inner Eye."

Harry heard a noise to his left and looked over to see that Percy had a strange look on his face, as if he were trying not to laugh. Thalia was elbowing him to get him to shut up, but she looked like she was also holding in laughter to some extent. Professor Trelawney either hadn't heard or didn't care. She continued in her introductory speech.

"So, you have decided to study divination, the most difficult out of all the magical fields. I must warn you now that if you do not possess the Sight, there is little I can teach you. Books can take you only so far in this practice."

Hermione stiffened in her chair, alarmed. Now it was Harry and Ron who were holding back snickers.

"Many witches and wizards who are talented in the art of loud bangs, flashes, and sudden disappearing, are unable to penetrate the veil of the future. It is a gift granted to few." Professor Trelawney had stood up and walked around the table that separated her from the students. She whirled and pointed to Neville. "You, boy, is your grandmother well?" She enquired.

"I-I think so," Neville replied nervously.

"I wouldn't be so sure if I were you, dear." The professor said mysteriously, leaving Neville looking extremely worried. "We will be covering the basics of Divination this year." Professor Trelawney continued on as if nothing had happened. "We shall begin with tea leaves, a simple method of predicting future events, and move on to palmistry next term." She again paused in her speech and turned to Parvati Patil. "By the way, my dear, beware a red-haired man." Parvati looked startled and edged away from Ron. "Eventually we will progress to the crystal ball; but we will be interrupted in February by a nasty bout of the flu. I myself will lose my voice. And around Easter, one of our number will leave us forever."

Seemingly finished in handing out dire predictions, Professor Trelawney paired them off and gave them cups of tea, instructing them to attempt to read the leaves of their partner's cup. Harry was paired off with Ron, Hermione went with Thalia, and Percy and Nico worked together. After drinking their boiling-hot tea, Harry and Ron swapped cups and looked at each others tea leaves. At the table next to them, Harry heard Percy complaining that it looked like nothing but 'a soggy brown mess' and Nico saying something about someone named Rachel. He tuned them out and turned his attention back to Ron's cup.

"Well…" Ron began, squinting into Harry's cup. "I think…that's a hat…maybe? I dunno Harry, it doesn't look like anything but bloody tea leaves to me." Suddenly Professor Trelawney walked up behind Ron and snatched the cup from his hands.

"Hmm, let me see…ah, the falcon, you have a deadly enemy."

"Well everyone knows that," Hermione said, sounding annoyed. Harry looked over to where she was sitting with Thalia, looking rather flustered. Professor Trelawney turned to her with slightly raised eyebrows, her expression unchanging, and Hermione continued. "Well, they do. Everyone knows about Harry and You-Know-Who."

Professor Trelawney turned back to the teacup and began examining it further, choosing to ignore Hermione. "The club…an attack…the skull…danger in your path…dear dear, this is not a happy cup…" Suddenly Professor Trelawney let out a loud scream and nearly dropped the cup before dropping to her chair by the fire. "My dear boy…my poor, dear boy…no, it is kinder not to say…"

Of course, that only made everyone want to know even more, specially Harry. Lavender Brown was the first to speak. "What is it professor? Please, tell us!"

Finally, Professor Trelawney opened her eyes and dramatically stated, "My dear boy, you have the Grim." Several people in the room gasped in horror, while the rest looked just as confused as Harry felt. "The Grim, dear, the Grim!" Trelawney said, seeing his confusion. "The giant, spectral dog that haunts graveyards! It is a sign of certain death!"

After Professor Trelawney cut their class short, the six wizards had headed outside before their next class. Ron was the first to speak about what had happened.

"Harry, you haven't happened to see a big black dog around have you?" Ron asked nervously.

"Yeah, actually, I have," Harry replied. "It was right before the Knight But picked me up.

"All of that 'seeing the future' nonsense is a load of rubbish." Hermione said. "Predicting the future is mostly just guesswork, if not impossible."

"Actually, predicting the future is possible, but only a few people can do it." Nico informed them knowledgeably.

Hermione turned to him with a huff. "Well now you sound just like her! How would you know that anyways?"

"Our…Divination Professor…has spoken quite a few prophecies, and all of them have come to pass." Nico replied. "But she isn't anything like that," he added hastily. "I agree with you about all of what we did in there; that was completely ridiculous. I'm just saying that predicting the future is possible; but not with tea leaves and crystal balls."

"So you're saying I don't have anything to worry about?" Harry asked as they began to make their way to the Transfiguration classroom.

Nico nodded. "Not that you dying isn't a possibility, but it isn't going to be shown by some random stray dog or some soggy tea leaves."

Harry wasn't sure if he felt reassured by that or not as they took their seats in Professor McGonagall's classroom. The rest of the Gryffindors seemed disturbed as well, and no one was really paying attention as Professor McGonagall began her lecture on animagi, wizards who could transform into an animal at will. He noticed that the Percy, Nico, and Thalia were paying attention, but they didn't seem that impressed, even when Professor McGonagall transformed into a cat right in front of them. To be fair, the rest of the class was to distracted to really give much of a response. Professor McGonagall transformed back into a human and looked at them all in disbelief.

"What has gotten into all of you? That's the first time that my transformation hasn't caused a immediate reaction. Someone tell me what is going on." She said sternly.

"Well, you see, professor," Lavender Brown began hesitantly. "We just came from Divination…"

"Oh, I see what it is now. Tell me, who is going to die this time?"

Hesitantly, Harry raised his hand.

"Professor Trelawney predicts a students death with every new class she has, and no one had died yet. It's her way of making an impression, I suppose. I assure you that you have nothing to worry about, Mr. Potter. You are in no danger of dying, so forgive me if I still expect you to turn in your homework on time."

Hermione shot him and Ron an I-told-you-so look, but Ron didn't look quite like he was convinced. Professor McGonagall continued on with her lecture, most of the class now fully reassured by her words.

"Alright everyone, repeat after me: Riddikulus!" Professor Lupin had led them into the staff room and explained that they would be facing a boggart. Now, he was teaching them the charm used to defeat the creature.

"Riddikulus," the class recited.

"Good. But, the word alone is not enough. I'm going to need a volunteer for this next part." He looked to the class, but everyone avoided eye contact. No one stepped forward. Harry didn't blame them; after all, who would volunteer to have their worst fear revealed? "Alright then. Neville Longbottom?"

Neville stepped forward nervously. He looked like he was stepping up to his death.

"Alright then Neville, first things first. What would you say frightens you the most?"

Neville whispered something, but it wasn't audible. "Sorry Neville, I didn't catch that,"Professor Lupin said kindly.

Neville took a deep breath before saying in a slightly louder whisper, "Professor Snape."

Everyone laughed, and Neville looked down sheepishly. Professor Lupin nodded thoughtfully. "Professor Snape…hmm…Neville, you live with your grandmother, correct?"

Neville nodded. "Yes, but I don't want the boggart to turn into her either," he said nervously.

Professor Lupin smiled. "No no, you misunderstood me. Could you tell us what sort of clothes your grandmother wears?"

Neville looked surprised and slightly confused as he answered, "well, always the same hat; a tall one with a stuffed vulture on top. And a long dress; green, usually. And sometimes a fox-fur scarf."

"And a handbag?" Professor Lupin queried.

"Yes, a big red one."

"Right then, can you picture those clothes very clearly, Neville?" Professor Lupin looked very eager for whatever he was about to do.

"Yes," Neville said, still looking unsure.

"Alright, when the boggart steps out, you step forward. It will see you and take the form of Professor Snape. You will hit it with the spell, while concentrating on you grandmother's clothes. Got it?" When Neville nodded, Professor Lupin continued. "After that, the rest of you will take a turn. Think of what you are afraid of, and think of a way to make it comical. When I call your name, step forward and hit the boggart with the riddikulus spell." Harry glanced around at the rest of the class. They all looked just as nervous as he was; Percy, Nico, and Thalia especially so. "Alright, is everyone ready?"

Neville stepped forward, wand ready, with a determined expression. Professor Lupin unlatched the rattling cabinet, and Professor Snap stepped out, a malicious gleam in his eyes.

"R-r-riddikulus!" Neville managed. There was a loud bang, and then Professor Snape was stumbling around dressed in a long lacy dress with a ridiculous looking vulture-hat on his head. The class roared with laughter, and Professor Lupin began calling students forward.

The more people that went, the more agitated Harry got. He noticed that Percy, Nico, and Thalia were looking more and more agitated; and even backing up in hopes of not being noticed. Harry didn't know what they were afraid of, but whatever it was it must be pretty bad. He was fairly concerned himself; he wasn't sure what he would do when it was his turn, because he was sure that the boggart would turn into a dementor.

"It's getting confused!" Professor Lupin shouted. "Percy!"

Percy looked startled, but before he had time to react, he was pushed to the front. The boggart changed form and became a deep pit in the ground. Harry was confused at first-was Percy afraid of falling into holes? Then he noticed two things. First, the hole emanated a feeling of dread, almost like the dementors, and Harry somehow felt that the pit housed things worse than even a dementor. The second thing he noticed was the girl. She had blonde hair, grey, terrified eyes, and she was clinging to a ledge inside of the pit, about to fall off.

Percy held his wand out in front of him, but his hands were shaking, and he couldn't seem to make himself say anything. Luckily, Professor Lupin stepped in front of Percy. The boggart changed into a round, silvery object. "Riddikulus!" Professor Lupin shouted, and the boggart exploded, the wisps of smoke that remained from it vanishing into the air.

Harry looked over at Percy, who had rejoined Nico and Thalia. He looked pale, and Harry saw that Nico looked disturbed as well. Thalia asked them something in Greek, concern evident in her voice. They both nodded shakily.

"Excellent!" Professor Lupin said, taking control of the situation. "Let's see…five points to everyone who tackled the boggart. I think that's enough for today. For homework, please read the chapter on boggarts and summarize it for me to be handed in on Monday. That will be all."

As soon as the class had filed out of the room, and Ron turned to Percy. "What the bloody hell was that, mate?! And who was that girl?"

Hermione hit him on the arm. "Ron! That's a very personal question!"

"It's alright." Percy mumbled, looking the most subdued that Harry had ever seen. "Her name is Annabeth. She's a…friend…of mine, from our…school." He didn't say anything about the pit, and Hermione was sending him and Ron a look that warned them not to ask.

"C'mon, we have Alchemy class next." Harry changed the subject, trying to distract Percy and Nico, who were looking depressed. "I wonder what Professor Elric is like."

Nico looked up with an odd look in his eyes. "Yeah, I wonder." He muttered.

They were walking towards the Alchemy classroom when suddenly Thalia turned and said, "Where'd Hermione go?" They all stopped and looked around. Sure enough, Hermione had vanished.

"She was just here not two minutes ago!" Ron exclaimed. "Where could she have gone?!"

Suddenly Hermione rounded the corner breathlessly. "Sorry, I, er, dropped a book back around the last corner."

"You could have told us, we would have waited for you," Percy said. Hermione only shrugged in response, and the six wizards continued walking.

Everyone entered the classroom and found seats, Harry and Ron sharing a desk, Hermione with Thalia, and Percy and Nico together. The exchanged unsure glances. They hadn't been given any textbooks, and they weren't what this class would require. Their questions were answered as Professor Elric turned to them and began speaking.

"Before any of you ask me any questions, I will say; no, I am not a wizard and do not do any of your hocus pocus nonsense, yes, I am fifteen and YES, I am in the military and therefore qualified to teach this class."

Professor Elric's golden eyes were flashing dangerously, and Harry got the feeling that he had been asked those questions in all of his previous classes, and that he was sick of them.

"Don't bother taking out you magic-sticks, you won't be needing them." Professor Elric continued. "Now, how many of you have taken chemistry?"

Percy was the only ones to raise his hand. Harry knew what chemistry was, being raised by muggles; but chemistry wasn't something that was taught to ten-year-olds, so even muggle-borns wouldn't have taken the class. Harry vaguely wondered why Percy had taken chemistry. Professor Elric looked surprised that even one person had raised their hand.

"Alright, how many of you know what the periodic table is?" He asked hopefully. A few more hands were raised, including Harry, Hermione, Nico, and Thalia. Professor Elric nodded approvingly. "This class will be easiest for you," he said, nodding to Percy. "I know that you 'wizards' think that 'muddle' sciences-or whatever you call us-are useless because you have magic. Well, if you want to learn magic, you're going to have to learn quite a bit of science."

He glared at them all, daring them to question him. Harry could hear Draco Malfoy scoffing from the Slytherin side of the room. Professor Elric turned towards him, eyes sparking.

"Is there a problem?" He asked, his tone dangerous.

"Well, sir," Malfoy sneered, "not only are you only two years older than us, you're also a muggle. No offense, but how much are you really going to be able to teach us?" It was easy to see through Malfoy's mock politeness; his real message was clear: 'You're too young, a filthy muggle, and I despise you.'

"Well, if you don't think I can teach you, then you can leave. You may have to leave regardless, depending on your level of intelligence." Professor Elric growled before turning away and continuing. "For anyone to be allowed to progress in this class, you must first find the answer to this statement: 'one is all, all is one.' Tell me what this means, and you may begin learning alchemy. If you can't find answer in one month…" Professor Elric paused and smirked slightly. "Then you will be removed from the class."

Harry's eyes widened, and the rest of the class looked startled, and started whispering immediately. Malfoy looked angry, but also determined. It was clear that he didn't want to let a muggle get the best of him, and that he was planning on answering the riddle no matter what it took.

"Quiet!" Professor Elric barked. "At the end of the month, you get one guess at the answer. One, and no more. And no complaining; you have it much easier than I did. You have access to a whole library, not to mention food. Now, does anyone have any questions that concern the class?"

Hermione's hand shot up into the air. "Yes, miss…?"

"Hermione Granger, sir."

"What is your question, Ms. Granger?"

"Sir, could you show us what exactly alchemy is? Everything that I have read about it said that it was used to change metal into gold, and to create the elixir of life and the philosophers stone."

At the mention of the philosopher's stone, something flashed across the professor's eyes, but Harry wasn't sure what it was. Professor Elric stepped up to his desk. He clapped his hands together in front of his chest, producing a ringing sound, then placed his hands on his desk. Blue lightning sparked around his hands, and slowly a statue rose up out of the wood. There was a chorus of gasps as the light faded, revealing a miniature statue of a suit of armer standing in a small crater that was now formed in the desk.

"This is alchemy," Professor Elric said. "Alchemy is not used to turn other metals into gold because that would ruin the economy, and it is certainly not used to make a potion for eternal life. Alchemy is the science of understanding, deconstructing, and reconstructing matter. In order to gain something, something of equal value must be given. This is the law of equivalent exchange. Alchemists live by this law, and it is the core of every transmutation. Your 'magic' completely ignores this law, so it will be harder for you to understand. But you must not forget this law, because if you do, you will end up badly hurt. Trust me, I speak from experience."

The classroom was dead silent. Professor Elric clapped his hands together again and touched the wood, changing the statue back into the desk. He then walked over to the chalkboard; where he had written a chart filled with different letters and numbers; and began explaining the periodic table. Harry quickly pulled out paper and a quill and ink to take notes. He could already tell that this was going to be a very hard, but very interesting class.

A/N-Whew, a lot happened this chapter, I hope you didn't get bored! Thanks for reading, Please review!
