(I always forget disclaimers, but it's in the summery of my story)

The RoR was filled with people, hammocks and mattresses filled the room, a small wall divided a small corner into a broadcasting station, contacting the order. A third or fourth year, I couldn't tell. He was talking into a microphone saying: 'Lightning has struck.' which I guessed was referring to Harry, meaning that Ron and Hermione and I were there too. Harry, Ron, Hermione and I were shoved around from person to person,

"EVERYONE SHUT IT!" Seamus finally yelled over everybody

"Thank you," he said when everyone was silent. "Harry, what're you here for?"

"You-Know-Who has something here, in the castle, we don't know what or where. It probably belonged to Rowena Ravenclaw. Does anyone have any ideas?" people started muttering, no one had any ideas, that's when Luna spoke up.

"What about the lost diadem of Ravenclaw?"

"Yes, but no one's seen that for hundreds of years. It's called the lost diadem of Ravenclaw." a girl, Cho I think, said. I think she was Harry's girlfriend for a little, but that's beside the point. She put emphasis on lost, she thought it couldn't be found.

"It can be found," I protested. "Just because it's lost now doesn't mean it'll be lost forever." I paused for a minutes, forgetting something "Hang on, what's a diadem?" a ripple of laughter rang through the room, 

"It's sort of like a crown, or tiara. There a statue of it in the Ravenclaw common room." she said, smiling at what I said before. Luna took Harry with her to the Ravenclaw common room, Ron, Hermione and I decided to get rid of the cup, since the sword's location was unknown. They took the cup down to the Chamber of Secrets, got a basilisk fang and destroyed it. I didn't go, only Harry got the parseltongue ability. I got mostly Poseidon stuff, but I have some slightly less obvious powers, like being awesome. 

I jumped through the door in the RoR wearing robes a fellow Gryffindor gave to me. We all made our way to the great hall. The houses were put into blocks, about ten by twenty. Each block was about two years of students. There were not many seventh years so we were added to the fifth and sixth years. Snape, the new headmaster, was pacing up and down the students. 

"Now, I have been informed that Potter and his friends have been seen in Hogsmeade, if anybody has any knowledge of events please step forward." he paused, "If you have information and are withholding it you will be punished as Potter is." Someone stepped forward, it was Harry. The crowd gasped, muttering about security.

"Tell them, tell them about how you killed him. You looked a good man in the eye and killed him." Harry was scowling at Snape, "But I think you have a bit of a security problem Professor. It seems rather extensive."  Almost the entire order walked through the doors.

Professor McGonagall walked up to Snape and shot a jet of fire at him, they dueled for a few minutes, but it felt like hours, Snape turned into a shadow and jumped through the window and flew off. He learnt that trick from Voldemort I guessed. 

Professor McGonagall cast Sonorus on herself,

"STUDENTS!" Her magnified voice bellowed, "All students under seventh year are not permitted to fight, we will be sending them home. Everyone to the Hogwarts Express. Now." Almost all the students left, some stayed to fight, much to some adults displeasure. But I learned to fight when I was their age, with no training. I stepped outside, Harry went to talk to the ghost of Ravenclaw tower, Helena. Hermione and Ron and I ran into the castle to make preparations for the battle. I already knew what to do, but I had to help Ron and Hermione. We secured the magical force field around the grounds, no one can come in or out. We didn't have armor but we put shield charms on our clothes and other people's clothes, less of a chance of death through undeadly hex or curse. There was a huge gang of snatchers, all of them combined I guessed. They didn't know about the force field, they ran through it and turned to dust, but the realized that this would keep happening, so before they lost all their ranks they stopped and glared at the invisible wall, now their ranks were twice as small, only about a hundred people. Maybe two hundred. We could take them Neville and I started to laugh at them, that's when a light hit the wall and it disintegrated. Neville and I ran for it, the snatchers were right behind us. 

Neville fired a curse and it hit the bridge, setting it on fire. The bridge crumbled and fell, we were airborne before I grabbed a piece of wood sticking out of the half bridge. I grabbed neville and helped him over to another part of the half bridge. We climbed up the criss-cross pattern of the bridge's supports and made it to the top. Ginny was there, her wand pointing at us, thinking we were snatchers, she sighed in relief when she saw it was us.

"Oh my Merlin, don't scare me like that." she said,  ""I thought you were snatchers who survived the fall."

"Nah, nobody can survive that fall, hitting water that hard is like hitting concrete." Ginny looked at me weirdly, "Muggle invention, it's like rocks all mixed together with a really hard to break sticking charm." I tried to explain. They seemed to understand. 

"I may be halfblood but I grew up in a mo-muggle community." I internally glared at myself for almost saying mortal. Ginny and Neville didn't look like they heard me so I just kept walking. I was walking when a huge crack was heard, the ceiling caved in, almost smushing me. I grabbed Neville and Ginny, Luna was running past us, I yelled at her. 

"LUNA! THIS WAY!" She looked over, there was a corridor. I knew, from the marauders map, that it led into the grounds. We ran into the hallway. Luna and Ginny were trying shield charms but nothing worked, I looked at Neville. He nodded, he concentrated and a wall grew, leaving enough light to see. 

"What was that?" Ginny asked, Luna seemed interested to know this too.

"Well, a few years ago I was in America, New York, and I was at a camp. How much do you know about the greek gods?" Neville asked, once we were done explaining Luna spoke,

"So, you also go to camp, Percy." she said, "'I go to Camp Jupiter, but I'm undetermined. My mother was a goddess. Probably Trivia." 

"Yeah, she's the goddess of magic. But how can Ginny be a demigod, I've met your parents, they are both mortal, well, wizard. But that's not the point. Maybe Hermes, I can see your brothers, Fred and George, being children of Hermes. Maybe your Hermes disguised himself as your dad or something? I don't know. Because she's not a pure wizard, she can see through the Mist." A glowing sign appeared above Ginny's head. A caduceus, with wings and two snakes. "Yes, I was right! Take that Athena" thunder rumbled, "oops, sorry?" I offered, 

"Okay, so what now, we need to contact the people from camp, tall them we need help. Anybody have a drachma? No, okay, I'll use this." I grabbed my last drachma, made a rainbow and threw it in.

"Iris o goddess of the rainbow, show me Chiron at Camp Half Blood." Chiron's face shimmered into the mist,

"Percy!" he said, surprised. "Chiron, we need the rest of the seven over here, now. There's a war and we need all the help we can get, any children of Hecate, Athena's children. This is magic, so no Ares cabin. Maybe some of the Hermes cabin, I want Ginny, Fred, George, and Ron to meet their siblings. Get some of the Apollo kids too, we need medics. I can ask my dad to get you guys, transport you. I don't know what else to do." 

I tried contacting my father, I thought as hard as I could 'Please transport necessary people from camp, we need some Hermes kids, some Apollo kids, the Hecate kids, the Athena kids ASAP (and a fez, comment if you got that, WHOVIANS UNITE).' There was the smell of salt and a flash, the people I asked to come were there, in battle armor. Hopefully magic proof.

"Hey guys, oh c'mon Annabeth, don't look at me like that. We couldn't give away our location. We need a plan, this is magic we're fighting, Heres kids, meet Ginny, your new sister, you have three new brothers. Ron, Fred and George." They grinned as they welcomed Ginny. They gave her armor and a knife. We headed to the grounds, there was flashes of light, we all threw ourselves into the fight. Stabbing, yelling and soon, screams of the dying, mostly it was the other side dying. Voldemort's voice echoed throughout the grounds,

"I SPEAK TO MY FORCES, RETREAT LET THEM TEND TO THEIR WOUNDED AND DEAD. HARRY POTTER, I NOW SPEAK DIRECTLY T YOU, YOU HAVE ONE HOUR TO COME TO THE FORBIDDEN FOREST, I WILL KILL YOU AND LEAVE. IF YOU DO NOT COME I WILL KILL EVERY WOMAN, MAN AND CHILD WHO STANDS IN MY WAY." We made our way to the great hall, a bunch of red heads were clustered around a body, George was crying the most, hie hugged Ginny, I saw who's body it was. It was Fred.

A/: OMG, I'm crying so hard right now, I loved the Weasley twins, because I'M a twin, duh. So I might bring Fred back to life, but IDK. I'm not updating until Monday, so bye for now.
