Harry didn't go back to the Dursleys that summer. He went to Number 12 Grimmauld Place with Cass. Little did he no that Dumbledore was panicking because the wards on Privet Drive had vanished.

The Black ancestral home was a nightmare. Mrs. Black's portrait was screaming bloody murder and there were decaying house elf heads lined up on the wall. Their first order of business was to take down the portrait. Cass and Harry took to it with jackhammers. Muggle devices did wonders. Next, Cass and Harry removed the house elf heads from the wall and buried them in the backyard. They even made mini tombstones for the elves.

While they were cleaning out dust bunnies, Cass discovered Kreacher. He immediately started praising her because she was Regulus' daughter. She asked him to tell her stories about her father. Kreacher said he would tell her the stories if she fulfilled her father's dying wish. To destroy Voldemort's locket Horcrux. Cass dropped the Horcrux off at the bank to be disposed of, and when she was done she gave the locket back to Kreacher. From then on, he cleaned the house, made delicious food, and told Cass stories about her father.

They hadn't gotten a reply from Flamel, and assumed he was just plotting his revenge on Dumbledore. Though it would have been nice to get a simple 'thank you.'

They were in the middle of dinner one night when they saw Kreacher tumble into the room wrestling another house elf. "Bad you! You is invading Mistress's house!" cried Kreacher, pinning the other elf down.

"Dobby has come to warn the great Harry Potter! He must not go back to Hogwarts! Bad things will happen! Promise not to go back to Hogwarts!" squeaked the elf.

"Should Kreacher kill elf? Kreacher's always liked a good beheading?" Kreacher asked gleefully.

Cass blanched. "No. Just find out which family he is from. Then Harry will decide what to do with him. He was coming here for Harry after all."

"Kreacher be doing that Mistress Black," Kreacher said, leading the struggling elf into an adjoining room. Cass looked at Harry.

"What do you think about this?"

"I'll write to Draco. He's from a pureblood family after all. He probably has had experience with invading elves before," replied Harry. He went to go write to Draco.

Hi Draco!

I hope you are having a good summer! Quick question, what do you do when a house elf shows up and starts giving you warnings? Also, do you know lots of the pureblood's elves names? This one is Dobby. Let me know if you can find out whom he belongs to. Kreacher, Cass's elf, is already on the case. Write back soon!

~Harry

Hi Harry!

Dobby is my elf actually. Can we have him back yet? On an unrelated note, I found this really cool book in my father's study. I don't want to share it with you though. It's mine.

~Draco

Hi Draco!

Vicious much, cousin? What kind of book is it? If it writes back then you should get rid of it. And no. Harry decided to confiscate your house elf.

Your very evil cousin,

Cass

Cass? How did you know the book…what was I saying?

Drom.

"I think Draco's demented," commented Cass, showing Harry the letter she had received.

"More like he took too many beatings to the head Mistress Black!" squeaked Kreacher.

Cass glared at the elf. Kreacher didn't take any offense. He knew she was kidding. "I'm actually really worried," she said, turning back to Harry.

"Me too," Harry agreed. Luckily, they were going to meet Draco in Diagon Alley to get their school supplies. Cass and Harry were so far disappointed with the Hogwarts curriculum, and were currently working on simple fourth year spells. Grimmauld Place was in walking distance from the Leaky Cauldron, so they didn't use the floo network. Harry didn't like the idea of spinning around in other people's fireplaces.

Flourish and Blotts was packed. It was a shame that they had agreed to meet Draco there. Harry was pulling out the supplies list when a blond-haired man with perfectly white teeth grabbed his arm. Harry did the natural thing when someone grabs you. He kicked him. Hard.

Gilderoy Lockhart screamed and ran over to a mirror to check his hair. Needless to say, the tabloid was taking pictures. Rita Skeeter could already imagine the headlines of the next newspaper. 'Gilderoy Lockhart Attempts to Kidnap Boy-Who-Lived.' Gilderoy finally got back from the corner after he composed himself.

"You are extremely lucky today!" Lockhart announced. Cass and Harry glanced at each other. "I will be teaching Defense Against the Dark Arts this year!"

"What is Dumbledore playing at? Does he want us to get killed?" asked Harry incredulously. Draco came up behind them.

"He uses more hair care products than me," announced Draco.

"And that's saying a lot," Cass added. Draco glared at her. Harry finally looked down at the supplies list. He promptly ripped it in half.

"What?" asked Draco, grabbing the ripped pieces. His eyes widened. "No way I'm getting those books!" They walked out of the store after getting the books, minus the Lockhart books, and were heading to Madam Malkins when they saw the Weasleys. And Draco's father. Not good.

"You must be the Weasleys," they heard Mr. Malfoy spit out in utmost disgust.

Cass poked Draco. "Can I please kick your father out of the family?" Cass pleaded. Harry motioned back to the confrontation, which was quickly turning into a fight. Arthur Weasley punched Malfoy in the face. Draco's father responded by dumping the Weasley girl's cauldron full of books over his head.

"Brawling like the filthy muggles," spat Draco, his eyes glowing a strange red. Lucius grabbed Draco's arm and they headed out of the store.

"What was that?" Cass asked worriedly.

"I don't know," whispered Harry.

oOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOo

Draco hadn't joined their compartment on the train ride. Harry noticed he slipped out of the Great Hall after the sorting. "Don't worry," said Harry, "I'll talk to him." Harry headed into the common room. Draco was sitting there writing in a diary. Harry snuck up behind him to see what he was writing.

I'm losing my memory Tom! It happened just on the train. What's happening to me?

Don't worry Draco. Nothing will happen to you as long as you keep confiding in me.

Harry immediately grabbed the book out of Draco's hands. "YOU!" Draco shouted, his eyes glowing red again. "Give it back!" Harry backed up and started running. Draco was following, shooting wandless spells at Harry's back that he normally wouldn't have been capable of doing. Harry found himself in the girl's bathroom.

"Slyther, what do I do?" Harry asked desperately. Before Slyther could answer, a giant hole in the bathroom sink appeared. Draco was nearing the bathroom. Harry threw himself down the grimy hole and ran.

"Open the chamber!" shrieked Slyther.

"What?"

"Tell the statue speak to me Salazar Slytherin, greatest of the founding four! Tell the master to give you some venom." Draco was rounding the corner.

Desperately, Harry said, "Speak to me Salazar Slytherin, greatest of the founding four!" A giant snake came out slowly. "Please give me some venom!" The snake replied by dripping some venom onto the ground. Harry slammed the diary to the floor on top of the venom and stomped on it. The diary let out an unearthly shriek. Draco collapsed. "I will come back later," Harry promised the snake, and he dragged Draco towards the entrance. "Stairs," he hissed. He then closed the chamber.

Cass was standing in front of the bathroom door, hands on her hips. "What in the world happened Potter?" she spat. Harry shrugged.

"Help me with Draco here," he said. She grabbed Draco's feet and they carried him towards the hospital wing. "Draco was being possessed by a diary. I think it was Voldemort's. It might have been a Horcrux. I destroyed it with Basilisk venom. I didn't have a choice!" Harry said desperately.

"That chamber can be useful for magic practice," Cass finally said. Harry dropped Draco on his head.

"What? You aren't going to yell at me?"

"No, I think running away from a possessed Draco was enough punishment." Draco chose this time to wake up.

"Which one of you dropped me on my head?" he asked angrily. Cass pointed towards Harry.

"But to my credit, I did save your life!" Harry added. Draco still didn't look pleased, especially with the egg-sized bump on his head.

"Well this was an exciting first day of school!" Cass exclaimed. Harry and Draco just glared.

oOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOo

They returned to the chamber on Saturday. Cass and Draco were put in charge of cleaning the chamber while Harry spoke to the basilisk. "Hello," Harry said. "What is your name?"

"My name is Arma. My name means weapon. I am here to protect the school. I would like to thank you for saving me from the control of Tom Riddle. He made me attack the muggleborn students. Only a speaker may command me," the snake replied.

"Would you like somewhere to hunt?" asked Slyther, sliding out of Harry's robes.

"Yes. I would. There is an entrance to the Forbidden Forest in the chamber. There are also entrances to Salazar's personal lab and library, and an entrance to the Slytherin common room. There is also an entrance to the Headmaster's office."

"Thank you Arma. I will open the entrance to the forest for you," Harry said. Harry opened the entrance to the forest and the basilisk slithered out. He found Draco and Cass tugging on a giant shedding of basilisk skin.

"We should sell this!" Draco exclaimed, unaware that Harry was right behind them.

"We're going to use it as armor," Harry said. Draco and Cass whirled around. "Basilisk hide is most likely stronger than dragon hide. Dragon hide protects people from most spells and curses," he explained. The chamber was fairly clean by that time, so Harry decided to try and find the secret entrances Arma was talking about.

Draco pointed out that there were lots of snake statues, so Harry spoke in parseltongue to one of them. A deep hollow sound came out of the ground, and a section of wall slid to the side to reveal a giant library.

Cobwebs weren't draped over everything like they expected. Apparently, spiders were afraid of Arma. Harry reached out to grab a book on elementals. Draco looked at him strangely.

"Harry, that isn't in English," Draco said.

"It's parseltongue, genius," snorted Cass. Indeed, the entire collections of books in Slytherin's secret library were written in parseltongue. On the far wall there was a large tapestry covered with Slytherin's family tree. Harry traced his way down the wall and stopped on his name.

"Let's go," Harry said suddenly, and he opened a passageway back to the Slytherin common room.

The next day they had Defense Against the Dark Arts with the Ravenclaws. They were headed to the classroom when the Gryffindors and Hufflepuffs burst out of the room screaming about Cornish Pixies. They walked in to find Neville hanging from his shirt collar on the chandelier, several Cornish Pixies tugging on his ears. Lockhart was sticking out of the window trying to grab his wand. Cass and Harry started freezing the pixies, and they were all safely locked back in their cages.

Lockhart finally managed to retrieve his wand, and started the class by rambling on about how perfect his teeth were and making bad puns. Then, he handed out a 'quick' quiz to see how much they knew. Harry wasn't amused by the quiz. He saw Draco insult Lockhart's hair and then lean back in his chair to sleep. Cass was scribbling away. Harry crumpled up the paper and put his head down on his desk and waited for Lockhart to grade the quizzes. Harry glanced over at Cass's quiz and laughed silently.

What is Gilderoy Lockhart's favorite color?

White, the same color of his unnaturally white teeth. Or green, because he makes you want to puke.

What is Gilderoy Lockhart's secret ambition?

To become the Sugar Plum fairy from the Nutcracker. He likes sparkles.

What is Gilderoy Lockhart's greatest achievement to date?

Not being in prison for fraud.

What would Gilderoy Lockhart's ideal birthday gift be?

A picture of himself.

What place does Gilderoy Lockhart call home?

The Ward for the Insane in St. Mungos.

What was Gilderoy Lockhart's defining childhood moment?

Being dropped on his head several times when he was a baby.

Luckily for this class period, Lockhart didn't let the Cornish Pixies loose on the class. Halloween was rapidly approaching, and Nearly Headless Nick was trying to convince people to come to his death day party. Which reminded Harry that his parents died on Halloween. He opted to skip the feast and go down to the chamber. Cass decided to come with him. Draco didn't want to miss out on the feast though. He had heard that there would be vampires.

Draco wished he had skipped the feast. Lockhart insisted on recounting his various battles…using the teachers as the ferocious beasts he was to defeat. Dumbledore didn't seem to mind acting, but Snape and McGonagall were tight lipped and wore scowls the whole night. The only people who enjoyed the feast were Lockhart's giggling fan-girls.

Meanwhile, Harry was reading a book to Cass, mainly because she couldn't read parseltongue. They were interrupted when Arma came slithering in. They shielded their eyes before Arma said, "Please tell me I can kill that annoying cat and that complaining cleaner. They don't even need to be here! It's a magic school! You kids have magic! Why can't you clean! Can I kill the greasy haired bat, or the long-bearded headmaster? Or the fraud? Please!"

Harry became stuck in a ferocious argument with himself on whether or not he should let Arma kill them. He eventually decided that Arma could petrify Filch and Mrs. Norris. The mandrake potion takes a while to brew after all. And while they are gone someone can realize their incompetence.

The day after Halloween, Mrs. Norris and Filch were found petrified next to Moaning Myrtle's bathroom. However, a seventh year Death Eater wannabe decided to write a little message saying that the chamber was opened. The students were in full-blown panic. Cass and Harry were wishing they hadn't had Arma petrify Filch and Mrs. Norris. Why? Lockhart was assigned to escort them to their classes. Harry and Cass were left debating how incompetent the teachers were. They didn't even realize it was a basilisk cat that petrified the caretaker and his cat!

When Christmas came, Harry and Cass were surprised to find invitations to the Malfoy Annual Ball. "My father must want to hang on to the rest of his estates," Draco commented. Draco then realized that neither of them had ever been to a ball. And that was how they found themselves in the chamber practicing ballroom dancing. More like Cass and Harry were practicing. Draco was laughing his head off when they stomped on each other's feet. Finally, they managed to get a simple waltz. With only a few minor stomp on the feet.

The day of the Malfoy Ball, Harry floed over to the house in his dress robes only to have Draco shove him back through the fire. "You have to enter with your date," Draco explained. Harry looked confused. "The person you come with. My cousin, Cass." Harry went back through the floo. Draco waited patiently for them to come. Cass suddenly came through the floo. Draco was exasperated. "Where's Harry?" he asked.

"I don't know. Should I?" Cass asked. Draco was tempted to bang his head against the wall. Luckily, Harry floed back through the floo.

"You two," Harry and Cass heard Draco muttering as he led them through the vast rooms with marble floors. They were in front of the doors to the ballroom when Draco stopped them in their tracks.

"Lady Cassiopeia Black, Head of the Most Ancient and Noble House of Black, and Mr. Harry Potter, Head of the House of Potter," someone announced. Draco nudged them and they headed into the room. Draco made an entrance with Pansy Parkinson and didn't seem so pleased about it. Harry and Cass began to dance as the music stated when they saw everyone else doing so.

"So," said Harry, "you look pretty tonight." He looked at her navy blue dress and curled hair.

"Thanks," Cass said brightly, stepping on his foot. The rest of the Malfoy Ball went off without a hitch.

Valentine's Day… not much so. Lockhart decided that bathing the Great Hall in lavish pink and sending cupids around to carry messages was a great idea. Harry didn't agree. Several cupids had started following him around, determined to deliver fan-girl messages. Harry finally sought refuge in the chamber. He vowed to get revenge on Lockhart.

The next day, Lockhart was bald and had puke-colored stripes running up and down his skin, and to top it all off, he had crooked yellow teeth. Harry had snuck into the DADA office through the chamber and charmed Lockhart's mirrors and portraits not to say anything about his new and improved look. Then, he slipped some potions into Lockhart's expensive homemade shampoo and soap and toothpaste. Harry also put some samples into his pocket for later. It was way to unnatural to look like that.

Everybody burst out laughing, and the Weasley twins tried to take credit for the prank. Snape looked smug, and as Lockhart ran out of the hall screaming he flicked his wand and the music serenading Lockhart began.

Lockhart had fled the premises after he managed to reverse the damage, and DADA was cancelled for the rest of the year. Meanwhile, Dumbledore wasn't happy. Malfoy was supposed to give the Horcrux to Ginny Weasley so Harry could rescue her from the Chamber of Secrets and fall madly in love. And if he didn't, he could just feed him a love potion. All in all, it was just a test for his golden boy. But Malfoy seemed to have misplaced the diary. Someone else was opening the chamber. And to make it all worse, Sirius Black had escaped from Azkaban.

AN: I finished the first and second chapter before I posted the story. The other chapters will take longer to be posted.
