Chapter Two: Long lost knowledge

Harry Potter had never spent so much time studying in the school library than this cold, rainy day in autumn. While Ron and Hermione were out in Hogsmeade, he read almost all the books about Dark arts that were not borrowed or in the forbidden section, but none of them had the information he searched for.

Nevertheless, he wouldn't have given up if he had not found the sentences: "All demon names are told to be written in the book of the signs of the zodiac. But this book disappeared in 1574 and has never been seen again. So if you meet a demon – what is not very likely, for they all are said to be banned in 1542 by a couple of great wizards – you better run instead of trying to call him by his true name."

Disappointed, he smashed the book on the table and thereby lost ten points of Gryffindor by Madame Pince, who also told him to leave immediately.

After all, he had wasted three hours of his precious time by chasing shadows.

Of course, he later thought, Dumbledore wouldn't have told him all that if he hadn't known Harry would never be able to use it against Snape.

But that didn't change the fact Harry desperately wished to use it against the greasy, slimy Potions master.

The question was, should he really break into Dumbledore's office to look if he had the book just to make Snape his servant?

Not that he had a chance to break in without Dumbledore knowing, but Harry liked the idea of having the decision.

He sighed.

It was hopeless. Absolutely. Totally.

It would have been great, though.

***************************************************************************************

Harry didn't know when he had begun wandering through the castle at night, but he knew he did it because he couldn't sleep.

Nightmares haunted him, most of them showed him Sirius' death over and over again.

And that was Snape's fault. He could have saved Sirius, but Harry knew he hadn't tried, though Dumbledore said something else.

Maybe the Potions master hadn't done it because no one had given him the order.

The boy took a deep breath and went down to the entrance hall. Not for the first time he was glad he had his father's Invisibility Cloak .

Unsure where to go now, he stopped and looked at the paintings on the walls. Some of the portraits were empty.

Harry wondered why they visited each other so late.

While he was fascinated by the paintings the entrance door opened and he heard steps coming down the stairs.

Without even thinking, he looked for refuge behind a knight, which stood beneath the stairs.

And as he saw who came in and who came down, he was glad he had acted this way.

Dressed in his black robe which he never seemed to change, Severus Snape stepped into the hall and he seemed to be in an even worse mood than normally.

Dressed in a dark blue robe, smiling, Dumbledore came down the stairs and went to Snape.

"I'm glad to see you're still all right, Severus," said Dumbledore.

"No need to be patient, headmaster. I have some information for you," replied Snape grim.

"You're late," continued Dumbledore without listening to Snape.

"The meeting was longer than I had expected," the Potions master answered the unspoken question.

"I want you to be true to me, Asmodi," said the headmaster softly.

Snape's face froze for just a second or two, than he snarled: "You know I am!"

Dumbledore nodded. "Of course. Let's go up and talk about what you found out."  

And without really realising it, Harry Potter had found out the name of one of the last demons... And achieved what he wanted since he had spoken with Dumbledore...

****************************************************************************************

It was two hours later when Harry saw Snape coming down again.

Without making noise he followed his teacher to his office into the dungeon and entered it before Snape closed the door.

He watched the Potions master taking place in a not very comfortable looking chair and remembered the times he stood here.

Standing in Snape's office meant – if you were Harry Potter – great trouble.

And now he was going to change the roles.

He wasn't afraid as he took of his Invisibility Cloak, or as Snape jumped out of his chair and looked at him with pure anger.

Harry Potter had the control, he knew it and he enjoyed it.

"Potter! What do you think you're doing here at three o'clock in the morning?" shouted Snape. "Fifty points of Gryffindor and run to your dormitory, or it will be 100!"

Harry stayed where he was.

"100 points of Gryffindor, Mister Potter. And now, as he have proved your stupidity and your stubbornness, I advice you to better leave my room before I make you leave it!" said Snape, dangerously calm.

"I don't think you're in the position to force anyone to do something, Snape. And I think you'll be giving me 200 points to Gryffindor for my smartness in less than a minute.

"Potter, are you having fever? For I believe you're hallucinating – not that I'm worried about you."

"No, Professor. I just found a long lost knowledge, you know," answered Harry.

"The only thing that I know is you'll be leaving now, Potter," said Snape and pulled out his wand.

"You won't do that."

"Why not? It's self-defence and no one will ever find out how much I enjoyed it," said Snape and raised his wand.

"You know, I had an interesting conversation with Dumbledore yesterday."

"I'm not very interested in your social activities, Potter."

"We were talking about fairy tale creatures," continued Harry.

"You really seem to be ill, Potter."

"About werewolves."

Snape panted.

"And demons."

Snape seemed shocked for a second, than said coldly: "I hope you don't have nightmares, now, Potter and want me to get you a potion."

"No. But tell me, Asmodi, isn't it frustrating to serve someone just because he knows your name? Ah, and would you please give me your wand?"

The Potion master froze, than, gave Harry his wand, his face filled with surprise and despise.

"I'm going to kill Dumbledore," Snape hissed.

"Oh, Dumbledore just told me you were a demon. He didn't tell me your name, if you believe that. I found it out as I heard your conversation in the hall. What a wonderful chance," replied Harry coolly.

"You're going to pay for this, Potter," said the Potions master.

"Well, I don't think so. I know your name, so you have to do what I say. Did I understand that correctly?"

Snape stood silent.

"You don't have to answer me, Professor. Your silence tells me I'm right."

Harry stepped forward, until his face was so close to Snape's that he could feel his breath.

"This is the revenge for Sirius," he whispered.

"I'm sorry to disappoint you, Potter, but I'm not afraid of you. I served the dark Lord, remember. And you are just a sixteen year old boy," replied Snape.

Harry grinned wryly. "I don't want you to fear me, Professor. I just want to take revenge."

"I can see no way how you could do that. Will you tell me to clean the cauldrons? Or to undress and run through Hogwarts? Please, don't let me prevent you from doing this."

"No, Professor, this would be no punishment for you. Even my father's tricks were worse. No, I want you to do something you really detest, though it will be disgusting for me, too."

"Ah, Potter, and what do you think could that be?" said the Potions master.

"Kiss me."
