Upon his return to the castle, Harry learned that Colin had fallen victim to the Heir of Slytherin. In fact, in between that attack and Harry's return another two students had been found petrified and strangely a castle ghost. Needless to say Harry could no longer afford to ignore what was going on.

So now Harry and his friends have gathered in the Room of Requirement hoping to form a plan of action.

"Ok let's review" said Hermione, pointing to a chalkboard provided by the room. "1: we know that someone called 'The Heir of Slytherin' attacked Mrs. Norris. 2: This same person has now attacked three students all of whom were muggleborns." She paused giving Harry a sharp look as if to say 'I told you so.'

"Ok Hermione, I was wrong. We shouldn't have ignored it" Harry replied, rolling his eyes. "Get on with it."

"3: The house elf that visited Harry, Dobby's master is most likely the Heir or at least aligned with them." Hermione continued, though it wasn't hard to miss the smug look in her eyes at having Harry admit she was right. "4: According to legend the Heir of Slytherin has access to a secret chamber containing some kind of monster."

"Alright so what do we do now?" asked Ginny. "We don't know anything about this monster or the Heir other than they're targeting muggleborns."

"We work with what we got" said Harry. "We need suspects."

"Well we can rule out muggleborns" said Ron stating the obvious. "So they're probably a pureblood."

"That makes sense" said Hermione, impressed with the youngest Weasley boy's reasoning.

"Well since he's the "Heir of Slytherin" wouldn't it make sense if they were in that house" said Neville. "Or at least have something to do with snakes."

"Not necessarily" Luna argued. "The Sorting Hat is supposed to judge students as individuals, not allowing other relations to influence it."

"Draco Malfoy" Harry deadpanned.

"Good point" Luna said in agreement. Despite being in the house of the ambitious and cunning, the Malfoy heir had yet to show any real signs of possessing either. Making it rather difficult to understand just why the hat had sorted him into that house. "Still it would make sense if Slytherin's monster was some kind of snake."

"And I bet Malfoy's behind it!" Ron exclaimed.

"I don't know about that Ron" Neville said, looking skeptically at his friend. "I mean he's always counted on his two gorillas to do his fighting for him. I don't think he's skilled enough to pull something like this off."

"But that's exactly why it could be him." Ron argued. "Think about he could just be sending the monster to the dirty work for him while he hides away."

"You have to admit, it does make sense" said Harry, nodding thoughtfully. Though part of him hasn't given up on the idea that Dumbledore at least knows something about what's going on. "But the problem is we don't have anything linking Malfoy to the Heir other than his family's history of being in Slytherin house."

"Don't forget he hasn't shut up about muggleborns being attacked" Ginny added. "What if his family's just been passing down the location of the Chamber for generation."

"Hold on, we need proof" Hermione interjected. "Remember the Philosopher's Stone?"

"Ok Hermione has a point" said Harry. It still burned him how he a trained ninja was a fooled by Quirrell's fake stutter. "We can't rush in blindly."

"There are too many unknowns" said Hermione. "We don't know the identity of the creature. The location of the Chamber. And our suspects are based entirely on conjecture."

"She means guess work" Luna translated for Neville, Ron, and Harry as they were confused by Hermione's choice of words. "And she is right we need more information."

"Why don't we just tail Malfoy and Dumbledore until one of them opens the Chamber again" Neville suggested.

"That might work for Malfoy but Dumbledore's too secure in his office" said Harry. "Plus it's not the easiest thing in the world to sneak past the paintings."

"So it's probably best to start with Malfoy" said Ginny. "But do we really want to wait for another attack?"

"So we'll make him talk" said Harry. "Get him alone and he'll cave to me."

"Hold on Harry. If you go scaring the ferret he might just lie" said Hermione. "Or worse if he is the Heir he might just let loose the monster."

Nobody liked the idea of Slytherin's monster being left to rampage. So it was decided to take a stealthier approach to the problem. And of course Hermione had just the solution Polyjuice potion. The magical potion would allow the user to take the form of another person. There was only one problem.

"The potion's recipe is most likely in the restricted section of the library" said Hermione.

"Couldn't we ask Prof. McGonagall to sign it out for us?" Ginny asked.

"No she might be on our side but I don't think she'd appreciate us looking for such an advanced potion."

"Which is why I went and got it?" said Harry, reminding Hermione that he can teleport around the castle just as easily as he could leave and return. "I took a picture with my T-phone."

"Oh right" Hermione laughed sheepishly, embarrassed that she'd forgotten her friend's most used ability. "Ok let's have a look."

Taking a look at the recipe it was discovered that brewing the potion would take about a month. Something that they weren't sure they had given the increase in attacks.

"If the waiting time wasn't bad enough it looks like the ingredients will be hard to come by" Ginny groaned.

"Forget that, what's that about us needing a part of whoever we want to turn into?" Ron demanded. "I'll tell you right now, I'm not drinking nothing with Crabbe's toenails in it!"

"At least we don't have to worry about that until the last minute" said Harry, trying to put a positive spin on the situation. "More importantly there's no way we can wait for an entire month."

"Well, Snape's sure to have some in storage right?" said Neville. "Maybe we can sneak some from his storage."

"Great idea, Neville" said Luna. "I'm sure he'll think it was the Wrackspurts."

"Ok I don't know what Wrackspurts are but I like that idea" said Harry.

A few nights later, under the shadow of darkness Harry snuck through the castle dungeons. His target Snape's potions storage. Earlier that day Ginny had gone to her brothers Fred and George for help finding the Slytherin Head of House's storage. Apparently the twins had a map that showed the castle's secret passages along with the names and locations of everyone within Hogwarts grounds. It was the secret to the twins' success; their one mistake was thinking that their nosy sister didn't know about it.

"You know you didn't have to come with me" said Harry, looking over his shoulder at Ginny.

"What's the point of all that training if I don't use it sometime" Ginny replied, checking the map to confirm their prize's location. "Ok it looks like Snape's personal potions storage is right through that door. Problem is Snape's inside."

"No problem" said Harry, a smirk spreading across his face.

In the dark of his personal potions lab, Snape toiled over a cauldron working on a restorative potion for the petrification victims.

Can't believe that bumbling fool Longbottom managed to best Draco Snape thought venomously. His mind clouded with anger over the fact that his Slytherins were beaten, even worse they were beaten by the friends of his hated rival's son. So clouded by his anger he nearly missed the wards on the room alerting him to someone entering. But when he turned to face the entrance, the door was closed with no sign of entry.

Cautiously Snape drew his wand, moving around the room his eyes scanning for the slightest hint of movement.

"Come out" Snape demanded. "I have no patience for fools." The next thing the potions master knew, he struck painfully in the back of the head before falling to the ground unconscious.

With Snape now out of the way there was a faint shimmer as Harry and Ginny came into view, with the former's invisibility cloak in hand.

"Oh man I've been wanting to do that forever" Harry smiled.

"Ok if I had any doubts about ninja training beating up Snape totally makes it worth it" said Ginny.

As Ginny began searching for Polyjuice potion, Harry decided to savor the moment. Meaning he took a selfie with his T-phone, posing as he stood victoriously over Snape's unconscious body.

"Hey if you're done I think I found it" said Ginny, laughing as Harry started spray painting a clown face on the potions master.

"Great we can leave right after one more pic" said Harry, prompting Ginny to join him in the photo.

A few hours later Snape would wake up on the floor of potion's lab. He would find no trace of intruders as he would overlook the fact this vial of Polyjuice potion was half emptied. In addition, he would fail to notice his new makeover until it was pointed out to him at breakfast. But that's another story.

In the present Ginny and Harry returned to the Room of Requirements triumphantly displaying the sample of Polyjuice potion taken from Snape's personal storage.

"Oh man I can't wait to see Snape's face at breakfast" Neville laughed as he and the others saw the picture on Harry's T-phone. Of course Hermione tried to pretend she didn't believe the foul man deserved such treatment.

"Well on to the task at hand" said Hermione, calling the group to attention. "We need to figure out when to go after Malfoy."

"The sooner the better" said Ron.

"I agree if we wait too long another attack might happen" said Luna.

"Ok but we need to be smart about this" said Hermione

"My brothers and I have always preferred the good old snatch and grab approach" said Harry.

"Sounds good to me" said Ron, grinning at the idea.

It was decided that the weekend would be the most ideal point to question Malfoy. Of course Harry didn't like the idea of leaving at first but his friends assured him that no matter what Malfoy told them, they wouldn't make any other moves until Harry had returned.

So with the reluctant Harry gone for the weekend Hermione, Ginny, and Luna waited in the Room for news of Neville and Ron's success in the capture of Crabbe and Goyle.

As they waited Hermione decided to make use of her time researching the possible identity of Slytherin's monster. Ginny practiced her katas, as she'd grown to find the exercise to be fun and relaxing. As for Luna, she spent her time sadly reading through her mother's notebook.

"Are you alright, Luna?" Ginny asked, noticing her friend's sorrowful mood. Moving to join the Ravenclaw on the couch the Weasley girl wrapped a comforting arm around her.

"Is that the notebook your mother made on The Kraang?" asked Hermione, moving to sit comfortingly on Luna's other side.

"Yes but mummy didn't just leave notes" Luna said sadly, pointing to the last family photo she had taken with her parents. Hermione and Ginny shared a look of concern as they realized they couldn't understand how much Luna had lost to The Kraang.

"Did you get any other messages from your dad?" Ginny asked.

"Yes he's found a new place to hide and sends his love."

"Don't worry Luna, Harry and his brothers beat The Kraang once. I'm sure they can do it again" Hermione assured her. "And this time I'm sure it'll be for good."

Luna gave her friends an appreciative smile just glad that she wasn't alone to deal with these feelings. The room fell into a comfortable quiet for a moment as the girls flipped through the family photos Pandora had left in her notebook. Though much to Hermione's personal frustration none of them were able to read anything concerning the witch's research into The Kraang or magic.

"Mummy was always cautious about her work" said Luna, explaining her mother's reasons for magically encoding her notes. "She must've been afraid of what could happen if they were stolen."

"And you don't have any idea what the counter spell could be?" asked Hermione but the younger girl didn't have a clue. The topic of Pandora's notebook came to an end as Neville and Ron then walked in.

"Any luck?" asked Ginny.

"Grabbed a few hairs from the gorillas and stuck them in a cupboard after leaving a couple of drugged cakes for them." Neville grinned.

"Honestly, those two are thick" Ron commented. "Who eats random cakes in a hallway?"

Hermione took the hair samples and placed them in two vials of Polyjuice potion. She explained that the potion would last only for one hour and that it was important that they question Malfoy and leave before then. So despite the potions mud like appearance Ron and Neville were then transformed into Crabbe and Goyle respectively.

"Wow I can't believe it worked" said Ginny.

"I know" said Hermione. "I mean, I read about it but actually seeing it…"

"Tell me about it" Ron/Crabbe muttered, examining himself in a mirror provided by the Room. "I'm just glad this isn't permanent."

"We'd better get going" said Neville. "We've only got an hour to find Malfoy."

"Actually it's more like fifty-eight minutes now" said Luna.

Once again thanks to Fred and George's map it was easy to find their target exiting a classroom in the dungeons.

"There you two are" said Malfoy with his usual arrogant drawl. "You two been pigging out in the great hall all this time?"

"Food good" Neville grunted, shrugging in what he hoped was in a Goyle like manner. Apparently it worked as Malfoy simply shrugged and led the way into the Slytherin common room.

Whereas the Gryffindor common room was designed to be warm, comfortable, and inviting; the Slytherin room was dark and dank, fitting for being located in the dungeons. The walls were a dark rough stone, illuminated by round greenish lamps and elaborately carved mantelpieces surrounded the main fireplace.

"So I hear another group of mudbloods were attacked" Malfoy snickered. "It's only a matter of time before the Heir gets his first kill."

Of course Neville and Ron knew about the most recent attack; a group of first year Hufflepuffs were found petrified the previous night. It took everything they had to convince Harry to leave for the weekend after he found out.

"I only wish he could go after Potter" said Malfoy, his arrogant drawl slowly becoming more sinister. "But I suppose it's only a matter of time. Honestly I'm almost thankful to old Lucius for releasing me."

"Wh-what?" Ron questioned, taking an involuntary step back.

"Yes now I can continue my noble work" Malfoy continued, his eyes turning a sinister red. To Neville and Ron's horror the ghostly image of a tall, dark haired, pale skinned teenager then appeared, overlapping over Draco's body.

"Like I said I only wish he could go after Potter" said Draco. "But I suppose I can start with his pathetic friends" said the ghostly teen.

Realizing that their ruse had failed Neville and Ron drew their wands as Draco/ghost teen began to hiss sinisterly.
