A/N: Some of it is mine, some of it isn't.
This is my first Harry Potter Fanfiction story, so please go easy. There may be some OOC-ness. AU, Sirius, Dumbledore, Severus, no one died.
Prologue
I am Klarissa Cain, Hogwarts' new History of Magic teacher. I am Albus Dumbledore's goddaughter and I fell in love with Severus Snape. That may sound weird, but I never said he returned the feeling.
Chapter 1
I walked into the Entrance Hall of Hogwarts School of Witchcraft and Wizardry and sighed. It had been a long time since I had been here, seen this hall, and seen the teachers even. The war was over now, Voldemort finished and the world restored to order. If you call the Ministry of Magic running everything and ruining everyone's lives. I sighed and started up the staircase, heading towards my godfather's office. I had just stepped in front of the gargoyle when someone ran into me. I fell straight onto my arse, the other person landing across me. They were heavy, so I took it to be another adult. I looked into the person's face to find that it was a man, a very tall man. He quickly stood and brushed himself off, ignoring me. He looked familiar, but I couldn't place him.
Rude. All men are rude. I thought angrily as I pulled myself off the ground.
"Forgive me." I said, nodding in his direction.
He grunted and continued into my godfather's office. I followed him. I was not about to be locked out of his office by a man that had absolutely no manners. My godfather was sitting behind his desk but he stood when I walked in.
"Klarissa." He said, smiling.
I threw myself into his arms, hugging him tight.
"It's so good to see you godfather." I said, my voice muffled by his robes.
I pulled back, my smile never leaving my face. There was a subtle cough behind us and I realized that the man was still there.
"Severus, this is my goddaughter Klarissa Cain. Klarissa, this is Severus Snape, Potions Master here at Hogwarts. Klarissa will take over the History of Magic job here at Hogwarts." My godfather introduced us.
Severus jerked his head in my direction and I stifled a giggle.
He obviously doesn't remember me. I thought.
"I am sure that your charm and wit must come out later on. Once you have decided to stop being an arrogant, rude ass." I said, smiling.
"Klarissa." Albus said in warning.
"Albus. I know my name. Do you?" I said cheekily.
Severus stared at me with a look of bewilderment on his face. Apparently, no one had talked to him like that before. Did he have a rude awakening coming!
"Perhaps you should go to your room and rest. The students will be arriving tomorrow and you'll want to be well rested." Albus said, gesturing towards the door.
"Okay, I'll leave you two to whisper and plan in private." I said good naturedly.
I walked out the door before Albus could say anything. But before I shut the door, I heard a little bit of the conversation.
"As you know Severs, Sirius Black and Remus Lupin will be coming to teach here this year. Lucius Malfoy as well, it's a part of his probationary time. I must ask you to keep your temper with all of them." Albus said. Then his voice dropped lower. "And watch over Klarissa. There are things that will come out in time, but she may still be in danger."
I shut the door and scoffed. I was still in danger. The men that were still loyal to Voldemort wouldn't be too happy with me at the moment, considering I was a Death Eater spy that helped defeat Voldemort and a few months before I was discovered, I turned down Voldemort's offer to be his lover. I mean, just because he looked like his seventeen year old self, didn't mean that everyone wanted him! And Severus, he didn't remember me. He had helped me leave this place! Yes, you heard right, I ran away from Hogwarts. I really didn't want to be here and Severus helped me get to a Floo Network and go back to Scotland. He was a wonderful friend, a good fellow Slytherin. I made my way towards my teacher's quarters, but bumped into two people along the way. I looked up to see Sirius Black and Remus Lupin staring down at me.
"Remus?" I asked, not believing it. He looked good, not that he didn't when I was a first year and he a third, but he looked good now.
"Do I know you?" he asked.
"It's Klarissa Cain!" I said, smiling. He was perhaps the only Gryffindor that hadn't made fun of me for being so small.
"KC?" he asked, and then I was being hugged.
He let go and looked me up and down.
"Still small and boney I see. How is Scotland these days?" he asked.
"Just bonny, love." I said, bringing out my Scottish accent even more.
Sirius was staring at me with his mouth open. He obviously remembered me; I think he should, considering he was one of the people that made me leave.
"Well, I have to go get settled in, but I guess I'll see you at supper or at the feast tomorrow. Come by my room if you want and I'll give you a good glass of Old Scots Brandy, see how you hold up." I smiled.
"I will!" he shouted after me, as I was already walking away.
"That's Small Bit Cain?" I heard Sirius ask.
"Don't call her that. And yes, that is Klarissa." Remus said reproachful.
I kept walking, happy that Remus stood up for me. I had almost made it to my room when I heard a voice that I never wanted to hear again.
"Why hello, Klarissa. Come to see your godfather?" Lucius Malfoy asked.
My blood ran cold. If there was one person that wanted to hurt me, it was him.
