It might be a little too late to mention, but I decided not to put Max and Rafe in the storie, even though he would be in there world by this time, because (spoiler!) Simon has already become a Shadowhunter and Angles Twice Descending and all that. Also the time line is of, the two stories take place years apart, but just pretend things would happen at the same time, if that makes sense.
As soon as they arrived in the Hogs Head, alarms started. A man was standing at the bar gaping at them. He looked like Dumbledore, with a long white beard and flashing blue eyes that could see right thru you. He pulled out his wand and called of the alarm, then turned on the group.
"Could someone please tell me why three of the most wanted people in the wizarding word, Magnus Bane, and a bunch strangers are doing in bar?!"
"We are standing in your bar because we need to get into Hogwarts, and Magnus, well, he said you could help." Hermione said shyly.
"And why would he say that?"
"Because you're part of the Order," Harry said.
"Bah! The Orders done! Finnished! Any one who believes otherwise is kidding themselves." The man said.
"Well, sir, your brother gave us a job, and part of that job involves getting into Hogwarts." Harry said.
"Why would my brother ever give you a job, if he cared about you so much? Nine out of ten times his jobs are suicide."
"I trust Albus Dumbledore. And when he asked me to do a job, I agreed to do it. I am the last hope we have over He-Who-Was-Not-Named and if you don't want to be living under his evil rule for the rest of your life I suggest you help us." Harry said, balling his hands into fist.
Aberforth sighed. "Follow me." He said, leading them down a flight of stairs to a small cellar with little to boast of. It was dark and damp, and the only color in the room was a huge, life sized portrait of a girl, standing in a blue dress on a path, leading over hills, surrounded by trees and fields of grazing cattle. Aberforth nodded at the girl. "You know what to do." He said. The girl turned around and started walking down the path.
"I'll go get you some food." Aberforth said, and started walking back but the cellar steps.
"That's Ariana. His sister." Magnus said, gesturing at the portrait after Aberforth had left.
"Poor girl," Hermione said. "Poor family."
"What happened to her?" Asked Clary.
"She had a sort of illness, at least that's what everyone called it back then. She was like an ifrit, but with wizards. They call them squibbs. Someone who is of wizard descent but born without magic. But of course a major magical family like the Dumbledores would never admit that. They already had enough bad press." Magnus said, his cat eyes glazing over, like they did every time he was remembering something.
"Like what kind of bad press?" Asked Simon.
"Percival, her father, was sent to Azkaban for killing some muggles." Hermione said dryly.
At this point Aberforth had returned down stairs with a big plate, heaped with biscuits and tea. Every one snached at he food greedly and wolfed it down in an instant.
"Shes back." Aberforth said. Everyone looked back at the portrait and saw Ariana, followed by another, familiar figure.
"Who's that she's with?" Asked Ron. The pair continued walking down the path, until the figure was clearly visible.
"Neville!" Harry said, just as the portrait swung open to reveal a long passage with Neville Longbottom standing in the frame. But Neville was beat up, with a black eye and swollen cheek, with several cuts and bruises all over him.
"Harry!" He cried. "You're back!" Everyone climbed into the passageway, all in a single file line, Neville in the front, Magnus in the back. As the portrait swung clothed he mouthed 'Thank you' at Aberforth before following the others.
"How long has this passage been here? I never saw it on the map." Ron asked.
"All the other passageways were cut off at the start of this year." Nevile started walking backwards so he could look at them better. "But none of that is important. Is it true you broke into Gringotts and rode of on a dragon?" He asked. "And who are this lot?"
"Yea, all of the stuff about the dragon is true." Harry said. "And this lot is a group of friends of ours. Helped us quite a lot. Made sure we didn't die." He smiled. "The blonde one is Jace, the redhead is Clary, the brown haired one is Simon. Behind him is Izzy, Alec, there siblings, and then behind Alec is Magnus. Group, Neville, Neville, group." Everyone waved and smiled.
"What's it like with Snape as headmaster?" Hermione asked.
"It's not Snape you need to fear, it's the Carrows. Brother and sister, they teach DADA and Muggle Studies respectively. They love punishment, make Umbridge look tame. They told me to put the Cruciatus curse on someone who had gotten detention. I refused. That's how I got this one." He said and pointed to a particularly long gash on his face.
"The sister, who teaches Muggle Studies always drones on about how Muggles are dirty, fowl animals, forcing wizards into hiding by being hideous and violent. I got this one-" He pointed to another gash. "-for asking her how much muggle blood she and her brother have."
"They've been using as a knife sharpener." Ron said.
"You would have done the same thing if you were there." They continued walking, until a large door loomed in front of them. Neville pushed it open and said "I told you he'd come back!"
There was a huge uproar of "Its Harry!" "Potter! It's POTTER!" "Ron!" "Hermione!" and so forth. Hugs and handshakes and shouts of glee were exchanged, while Jace, Clary, Simon, Izzy, Alec, and Magnus stood awkwardly in all the hubbub, trying to not be noticed.
"Alright! Alright!" Shouted Neville. "Harry's come here for a reason. Would you mind telling us that reason?"
"So, um, we're looking for something. Something small but important. Most likely has something to do with Ravenclaw. Has a lot of history, probably, " Harry said.
"Could you elaborate?" Someone in the crowd asked.
"No, but-" Just as Harry started to explain not even they knew what they were looking for, the portrait door swung open again too admit more people, Lupin, Tonks, Luna, Ginny, Mrs. Weasley, Mr. Weasley, and other Order members started to pour into the room.
"Oh!" Cried Luna, once everyone had been settled again. "I think I know what you could be looking for! Rowena Ravenclaw's lost diadem!"
Magnus frowned. "It would work, but the thing is, it's lost. I suppose you could talk to Helena, but…" He trailed of.
"Of course! I can go with Harry so we can ask Helena, then come back here to tell you what she said."
Ron cleared his throat. "I actually, well, have an idea on how we get rid of if." He said, clearly trying to avoid using keywords. "I was wondering if I could go with Hermione too see if it would work." Just as Harry was going to give Ron the OK, a thundering, clanging bell rang through the castle. Everyone sprang up and pulled on cloaks, moving frantically to the door.
"Whats going on?" Asked Mrs. Weasley.
"We have to go, that's the emergency bell. We all have too meet in the Great Hall. They'll kick us out if we don't report too it." Neville said, rushing to the door.
"Neville, I think I'm going to come along, I have a plan." He said, pulling on an abandoned Gryffindor cloak. "Everyone else, wait ten minutes, then go to the Great Hall. Wait outside the doors until I give to the signal." He said, racing out of the room too follow Neville.
The door slammed shut behind him, resounding against stone walls. Every stood in an awkward silence for awhile until Jace said, too no one in particular, "The weathers nice today."
"It is indeed." Said Shacklebolt uncomfortably.
"Did you forget your line?" Simon muttered under his breath.
"Yes, could the director please hand me my script?" Clary giggled, acting along.
"What are you getting on about? Who are you people?" Mrs. Weasley asked.
"Darling, I think they're talking about a fascinating thing called movies." Mr. Weasley said, eyes gleaming with intrigue.
"On who we are, I'm Magnus Bane, High Warlock of Brooklyn, and these are my friends. Alec, Clary, Simon, Izzy, and Jace." He said, pointing to each person respectively "There Shadowhunters."
"What what might a 'Shadowhunter' be?" Asked Remus.
"Never mind that now, our ten minutes are up. Could someone lead us too the Great Hall?" They left the room in a rush, running too the Great Hall as fast as they could. As soon as they arrived they heard Harry's voice seeping in under the cracks in the great wooden doors. He said: "You can come out now."
Shacklebolt threw open the doors and everyone strode in. Students were pressed against the walls, and Harry stood in the center of the Hall, head over his shoulder looking at the massive group that would stand with him.
Harry turned back to look at Snape, who was standing at the head of the Hall, were the teachers table normally stood. His hand reached lightning fast into his swirling black robes and pointed it his wand Harry. Immediately, Professor McGonagall raced out in front of Harry and extracted her wand. She waved it furiously at Snape and a burst of fire shot from the end, but Snape was not caught of guard. He conjured a shield. McGonagall sent another ball of fire spinning towards him. He conjured another shield. He looked directly at Magnus and yelled, "Don't tell him!" And leaped out of a near window, shattering the glass and flying away into the night like a bat. "Coward!" McGonagall shouted, shooting one last fireball at him, before turning to Magnus.
"Don't tell him what? Who is 'him'?" She asked.
"I made a promise that my lips were sealed. I can't say anything."
McGonagall seemed to be searching for words. "Are you sure?"
"Do you not understand what a promise is? I told Dumbledore I wouldn't say anything. It isn't my place too say anything, I was never supposed to even meet any of you. And I intend to keep my word."
"But Dumbledore is dead. He was killed by that man!" Harry said, pointing out the broken window. "He trusted Snape, and look where that got him. Killed at the top of the Astronomy Tower!"
Magnus sighed, but it was not a sigh of defeat. It was a sigh of pity, like he knew something Harry didn't. "If you knew the whole story, I think you might disagree." Harry opened his mouth, but didn't get too say anything, because a great buzzing sound filled everyone's ears.
I need Harry Potter. Said a voice, coming from nowhere, but resounding everywhere. It was clearly the voice of Lord Voldemort. Someone bring me Harry Potter. You have till midnight to bring me Harry Potter. I will leave Hogwarts untouched is you bring me Harry Potter. The buzzing stopped, and the Hall was filled with an eerie silence.
"Well?" Some with a Slytherin robe yelled. "Someone get him!" Hermione stepped in front of Harry. Ginny joined her. Soon, Harry had a circle around him. No one was taking Harry under their watch.
"Filch!" Yelled Professor McGonagall. A grimy man with a yellow-eyed cat scrambled up. "Yes ma'am?"
"Take the Slytherins down to their common rooms." She ordered. Filch waved one hand in the air. "Common then!" He yelled, leading the Slytherins out of the Great Hall.
"Everyone else!" McGonagall shouted. "If you are seventeen or up, you may fight. Everyone else, follow Professor Slughorn to a safe location where you can be escorted home." Everyone under seventeen started filling out of the hall, but Luna and Ginny and some other sixth-years stayed, but Professor McGonagall said nothing about it, and let them stay. Mrs. Weasley huffed her disapproval, but didn't argue.
McGonagall started issuing something that sounded a lot like was issues that a general might make. She told people where they were going to stand, were too guard, what protective spells to cast. Finally, only Harry and the others, and some seventh year students Harry had never spoken to were standing in the Great Hall with the Professor.
"What can I get for you, Mr. Potter?" She asked.
"Time, Professor, as much as you can get me."
"And you friends?"
"Ron and Hermione are going to go do something already planned out, and I guess Clary can go too."
"And Simon. He's my parabatai. Were a package deal." Clary said defiantly.
"Okay, and Simon's going with them. The rest of us are going to look for Helena Ravenclaw. Alright. You guys go do your thing, we'll do ours." As everyone left, he turned to Professor McGonagall. "Thank you." He said, following his friends too find Helena Ravenclaw, ghost of Ravenclaw tower.
I don't think I'm going to include what happens in the Chamber of Seacrets, because everyone knows what happens there. We also need some good one on one conversations. Thanks for reading and don't forget to comment!
