When Worlds Collide (Harry Potter, Percy Jackson and Twilight Crossover)

Chapter 20- Liana's POV

I waited for the other students and had Draco and Gin standing on either side of me. Minerva and Sev were behind me, willing to give protection I didn't need. The students marched into the Great Hall and stood in their different houses, like an army. It was so sad and cruel. "Carrows!" I barked. They walked up to me with evil glints in their eyes. Throwing my palms out towards them, they were flung back with my powers I got from my father.

"What the bloody hell Lady Death?!" One of them yelled, furious. I never bothered to know their names. It was the girl though, the guy was clutching his head in pain.

"Don't call me that!" I yelled. "I'm Liana Quinn Cullen. I infiltrated Voldemort's inner circles and became his number one prodigy because Albus Dumbledore asked me to! I am easily one of the most powerful people, demigod and vampire because of all my powers! It was all fake and I cry at what I did to the man that helped me, saved me by helping me learn my powers! I have nightmares every night at what I do to help people! You can tell Voldemort to shove his wand, which HE STOLE FROM ALBUS, right up his arse!!!" Everybody who didn't know was taken aback.

"I quit too. Liana, can you help me get this thing off?" Draco asked. "I was forced into it by my bloody parents." Everyone was quite alarmed as I took out my wand and muttered some words, removing Sev, Draco's and I's Dark Marks.

"The Dark Lord shall hear of that and you will pay!" The other twin said. I groaned in annoyance at their existence.

"Would you just shut up!" Gin yelled and shot a curse at them, throwing them back into the wall and killing them. She was applauded by every other house besides Slytherin.

"Harry, Mione, Ron, where are you guys?" I asked into the Gryffindor crowd. It parted to let them through and I rushed to hug them. Harry held me for so long and so tight I thought I wouldn't be able to breathe. "H-Harry..." He let go quickly.

"I missed you so much! Mum and dad have been so sad, that whole side of the family is a wreck. They missed you and were so worried. Jake disappeared for a few months but then came back, mostly for Sky. The girls are all grown up!" A tear fell as he talked about mum and dad, and everyone else.

"I'll see them soon. Mione, thank the Fates you understood. I was so worried that I would loose part of my family-" A cold, unwavering voice was heard through the castle.

"I know that you are preparing to fight. Your efforts are futile. You cannot fight me. I do not wish to kill you. I have great respect for the teachers of Hogwarts. I do not want to spill magical blood. Give me Harry Potter and Liana Cullen, and none shall be harmed. Give me Harry Potter and Liana Cullen, and I shall leave the school untouched. Give me Harry Potter and Liana Cullen, and you will be rewarded. You have until midnight." His voice rang out in everyone's head, cold and no emotion. A girl screamed and I rushed to her, holding the little first year Gryffindor to me.

"Well, what are you waiting for? Get them!" Pansy Parkinson yelled. People started moving towards Harry and I but they moved around us to protect us. Harry, Mione and Ron were in a triangle, guarding me. All the Gryffindors, most of Ravenclaw and some of Hufflepuff moved around us.

"Mr.Filch, please escort the Slytherin House down to the dungeons and lock them in." Minerva said. I'm just fine with having her take over, she mostly did everything but I was learning to do it myself anyways. I do like being headmistress, just not like this. All the other houses cheered as the Slytherin House was leaving.

He tried to take Draco too but I stepped in. "He stays." I said. Filch glared at me before I made lightning crackle outside. He quickly stepped away and forced the Slytherin's out.

People started apparating into Hogwarts and I recognized my parents. "Mum! Dad!" I yelled. They turned with lightning vamp speed and caught me just in time as I jumped into their arms.

"Lia!" They yelled in happiness. "4 YEARS, WE HADN'T HEARD FROM YOU FOR 4 YEARS!" And that was Auntie Alice.

"Hey Aunt Alice, Uncle Jasper, Grandpa Carlisle, Grandma Esme, Sam, Jake and Seth. Miss me?" I joked. Hugs went around and Jake threw me over his shoulder.

"Where's Percy?" Mum asked. I froze and all the emotions I had locked away sprung out of the box I had locked them in.

"Annabeth Chase, my old best friend, pushed him into Tartarus because he loved me. He proposed to me almost a year ago and then Hera kidnapped him, took his memory away and then placed him in a camp. 8 months, that's how long he was missing till Piper McLean managed to find him with my half-brother Jason Grace and their friend Leo Valdez. Chase pushed him into Tartarus not long after they found him again and I still hadn't spoken to him!" I screamed. "He was staying with me in the house that Albus gave me and then when I went home one weekend to see him and I find that my wanker of a step-mother kidnapped my fiancée!" I walked away and locked my emotions away.

"Liana, you're the front lines. Can you do that?" Minerva asked me. I nodded with a hard look in my eyes.

"Let's do this." And with that, everyone who had arrived and the students that stayed were sent off to their stations and I was in the Courtyard, where the first attacks were going to happen. Shields, powerful ones at that, were being put up around the castle but I focused on the Death Eaters that I saw on top of the hill.

Voldemort shot a powerful spell at the now finished shield and it was slowly breaking. I knelt down on the ground and focused a small part of my power on the shield. It didn't take much to keep it repaired but I would run out of the energy soon. "Lia, let them through. We need you to keep your energy." A voice said from behind me. I looked behind me to see an IM from Thalia.

"Thals." I whispered. I wanted to rush to her but I knew she wasn't real. Camp Half-Blood was preparing for war behind her. "I know. I miss you so much." A smile graced her face and I returned it.

"Do this for Percy, he'll be fine. Seaweed Brain may do something stupid but he will do anything for you, even walk in Tartarus." Thals said. I wiped the tear that fell and said goodbye before swiping through the message.

There was a battle cry before the shield that surrounded the castle broke. The Death Eaters charged and I knelt on the ground again. They laughed as they came to stand in front of me. "What are you going to do, pray?" Bellatrix sneered. I didn't look up and took a deep breath and closed my eyes.

They charged again and I pushed them back using my powers. They were surprised as I was lifted off the ground and lightning struck everywhere. There were screams of pain and shock from the Death Eaters as I lowered their numbers greatly. I created a shield around myself, blocking any spells.

Most of the Death Eaters were killed but there was still a large amount of them left. My energy was drained and I fell towards the stone Courtyard. It was coming fast but before I blacked out, I was caught by somebody. All I heard was, "Not my baby sister." And then I blacked out.
