HARRY POTTER AND THE BURNING HELLS

by CreatorZorah

Chapter 1: Sanctuary

"Clean this room. No magic is allowed," Filch said. "I'll come back later to see if you're doing your work properly. Understood?"

"Yes," both Harry and Tracey answered in a very displeased tone.

"Come, Mrs. Norris," the caretaker said, heading out of the dungeons.

Tracey glanced at Harry and said, "Potter."

"Davis," Harry said.

"Get to the work," she said sitting down on a crate.

"I won't work while you're doing nothing!" he exclaimed.

"Great! We'll get another detention when the Squib comes back."

Harry glared at the redhead and said, "I don't care."

"Well, I don't care either," she said taking a book out of her robes to read.

Seeing that the girl really didn't move to clean the room, he growled, "Fine." With that he sat down on another crate and took his copy of Advanced Potion-Making. Unfortunately the old crate, he chose, couldn't bear the weight and collapsed noisily. Harry felld down and scowled as Tracey burst out laughing.

"You should become a clown, Potter."

"Oh, shut up, Davis," he said, dusting himself off.

"What? You're good at making people laugh," she mocked.

"Ha-ha," Harry uttered grimacing at her.

As he started to study contents of the crate he saw a few old rusty swords, some kind of medieval leather armor, a few books, scrolls, some other things and... the staff. It was one and a half meter long, made of some dark wood. There was a large green crystal on the top of the staff and it was... glowing? "What for Merlin's sake is this?" he mumbled and took the staff in his hands feeling surge of magic from it. It felt like a wand, but... so powerful!

"Merlin's pants, Potter," Tracey gasped jumping of the crate and rushing to him. "Where did you find it?"

"It was in the crate."

"It's a sorcerer's staff," she said, examining it. "These weren't seen for three thousand years! How did it get into this bloody crate?"

"No idea. What's so important about the staff?"

"Do you read books, Potter?" she asked. "The last sorcerer was seen three thousand years ago. It's thought to be a legend. I thought it was one until now too."

"Well, aren't we sorcerers too?"

"Bloody hell, no! We can be, but we aren't. We use words like 'sorcery', but we have no idea what it really is. Unlike us, sorcerers knew secrets of magic, they knew how it works. They didn't need wands or staves to do magic. If the legends are right, then there were only three of them. and they never taught anyone before vanishing without a trace."

"So, they're practically more powerful than us?" Harry asked forgetting that he was speaking to a Slytherin.

"I have no idea. We can be powerful in our own way. But the things they did according to legends are... disturbing," she said and took a book in her hand, opening it. "It's Greek," she said.

"You know Greek?" Harry asked in surprise.

"Yes, Potter. A lot of old manuscripts are written in Greek," Tracey explained, reading the book at the same time. "It's amazing! These are basics of sorcery!" She opened the other two books. "All this is about sorcery!" Tracey exclaimed. "Potter, give me the bag," she said pointing at some plain leather bag.

"Why?"

"We should hide all this, dumbarse. Or you wish to hand it over to the Squib?"

"Eh... you're right," Harry said and handed her the bag.

Harry helped her to gather all small items and stuff them into the bag, before Tracey cast the Notice-Me-Not charm on it. He kept the staff in his hand, however, not trusting the redhead with obviously powerful weapon.

Tracey glanced at him and asked, "How do you plan to explain the staff to Filch?"

Harry sighed. "I'll just hide it. Will you place it under the Notice-Me-Not charm for me?"

"Don't tell me you don't know it, Potter," she said stunned by his question.

"I don't. I'm good at fighting, not trickery."

"Right." Tracey nodded and sent Reductos at other crates. Sadly, they turned out to be empty. She shrugged and took a scroll out of the bag. "Curious, what's inside," she muttered, opening it.

That's when everything went to hell. A blue archway appeared out of nowhere. It was glowing with the light intently. Tracey was too close to it and the portal began to suck her in. "Potter, help me!" she screamed in panic. Harry rushed to the redhead and grabbed her at waist, but it didn't help, mere moments later they both, the bag and the staff were sucked in. Harry was prepared to die, but to his surprise after a second of weird feelings he slammed onto the cold stone floor with Tracey on top of him.

"Are you alright?" he asked.

"What?" she asked opening her eyes. "Where are we?"

"I have no idea and I don't see a bloody thing. Would you please... well," he said.

"Ah... right," she said, standing up. "Lumos Maxima!"

"Davis! Give me a warning next time," he complained.

"Do you want a next time, then?" she asked slyly.

"Where the heck are we?" he asked looking around.

"I have absolutely no idea, but I doubt it's Hogwarts," Tracey said.

"Yeah."

It was quite clear they weren't at Hogwarts. The Hogwarts didn't have halls like this, the eastern architecture of this place seemed to be a lot like pictures of Egypt he had seen. Besides he was sure, that they wouldn't find old skeletons lying around.

"Is that some kind of tomb?" he asked.

Tracey frowned and answered clearly uncomfortable with the idea, "Looks a lot like a tomb of some Ancient Egyptian wizard."

"Did that scroll portkeyed us to Egypt?"

"I doubt it. Let's try to get out of here," she suggested and used a spell to find an exit. "Magic feels different here."

"How?" he asked, taking he staff and handing over the bag to Tracey.

"Try it yourself, Potter," she said moving to the exit.

"Lumos," holding the wand in his hand. The stick glowed much more brightly than he expected. "Whoa, it's like... like I have a lot more... magic here."

"Exactly," she agreed grimly. "That bothers me a lot."

For the next few minutes Harry followed Tracey silently to the exit. It was creepy, but quite alright until they entered small square room. The redhead stepped on a stone and it went down under her foot. She squeaked in surprise, missing a bunch arrows that were launched at her by this trap. Harry, however, reacted very fast shielding them with simple, "Protego!"

"Bloody thanks, Potter," she said. The moment later her eyes widened and she exclaimed, "What the hell?"

Harry turned around and blanched seeing tons of skeletons approaching them. "Run!" he shouted, dragging the girl with himself.

As they advanced to the exit, skeletons on the floor were beginning to move and standing up. Some of them had weapons in their hands, others tried to grab them using hands. They didn't try to fight them for there were too many, but every now and then they had to send banishing charms at skeletons to get through the horde of undeads. The pair didn't dare to slow down, since they would be swarmed.

"There!" Tracey exclaimed breathing hard.

Horrified, they both saw that wherever the exit was, it was blocked by an solid stone plate. On reflex Harry shouted, "Reducto." He didn't notice that he used the staff instead of wand. The stone plate exploded like it was just pile of dust.

Tracey reacted instantly sending a silent Wingardium Leviosa at the boulders that would bury the way to the safety otherwise. The moment they left the tomb she ended the spell blocking the exit for undeads and fell down on the sand looking at the sky. Harry sent an Reducto at the single skeleton that managed to get through and sat down beside Tracey.

"We're safe..." Harry uttered after few minutes of silence.

"I wouldn't be so sure, Potter," Tracey said.

"Why?" he asked.

"Look at the sky."

"What's with the sky?"

"Oh hell, Potter, did you learn anything in Astronomy?"

"Wha..." His eyes widened, when he didn't find any familiar constellation. "What? How could that be possible? Where are we?"

"Beats me! Anywhere but our world."

"Give me the bag, I'll try to open another scroll," he suggested. "Perhaps it will send us back."

Tracey nodded and took another scroll out of the bag. "What if it sends us somewhere else?" she said handing over the scroll reluctantly.

"Well, we'll know it once we try," he said smiling and opened the scroll. And... nothing happened.

"I believe, we're stuck here... wherever this here is," Tracey said sighting. Then she suddenly said, "Good. We won't have to participate in that stupid war with You-Know-Who."

Harry paled again at that and exclaimed, "Oh Merlin, I have to get back!"

"Relax, Potter, you aren't the center of the universe, neither is the sun shining out of your arse. They'll handle it without you. Somehow."

"Don't you care about your friends?" he questioned angrily. "Or family?"

"Nope," she answered. "I don't have any."

Harry wanted to tell her that she's heartless, but when she heard the last sentence he stopped. Instead he said, "But I saw you talking to Malfoy, Parkinson and..."

"You saw, I guess, but does that make me friends with them? No," she said. "Did you ever heard of a wizarding family with the name Davis?"

"No," he said.

"Because there isn't one. My father was a muggle, mother a pure-blood. But they were killed by Death Eaters before you managed to defeat You-Know-Who. Not the best ancestry to be in Slytherin same year as Malfoy, Crabbe, Goyle, Nott and Parkinson. I'm hanging out with their lot because I don't want them questioning my loyalties. Now answer me, please, why should I want back if it's possible that I can live here peacefully?"

"I'm sorry, I didn't know," he said feeling foolish. "Though if the whole world is like this tomb, I doubt you'll have a peaceful life here."

"Yeah." She snorted and stood up. "Perhaps the Hogwarts is the better choice. Anyway, we have no choice and should find some town here if there are any."

"Skeletons were human," Harry noted.

"Right, hope there are living humans as well. Do you know any useful spell for such situations?"

"Not really," he answered. "You?"

"I don't know either."

"What about that spell you used to find an exit?" Harry asked.

"That's what it does. Finds an exit." She sighed. "I'll be using the Point-Me spell to avoid going around in a circle."

"Alright, let's walk north," he suggested and then shouted, "Lumos Maxima!"

The potency of magic in this world along with the staff made the spell very powerful. Both Harry and Tracey had to close their eyes as he sent the glowing ball to the sky. The desert became so light like it was a day. A very dark day, but still...

"That was awesome, Potter," Tracey said. "I have to get the staff like yours."

"I can't believe it either," he said looking bewildered at the effect of the spell. "Let's go."

A/N:

Well, I didn't expect to write this story, but I couldn't resist the urge. The world of Diablo is rich, but kind of... stupid. At the same time I like the idea of all these demons and angels.

So when I decided to write something, I had to choose: do I want Harry in the Diabloverse, or should I put Evils into the Potterverse? In the end, I couldn't really decide, so I chose both. Let Harry fight Evils in the Diabloverse and then get him and Evils back to the Potterverse and continue the fight there :)

The next question was, should I create portal for one person (Harry), or get him some friend? It would be quite boring to write about single sexy Harry, so I decided to get him some sexy girl. To make things more interesting the sexy girl has to be a Slytherin. I kind of hate Pansy and I don't want to use Daphne. So... Tracey? Yeah, the sexy and fiery redhead ( in my stories she's always a redhead) gets Harry.

Time. I decided to give them a year in the world of Sanctuary before getting to the story of Diablo III.

I don't know a lot about the world of Sanctuary, so beware of possible mistakes. Don't expect much of it. Right now I have only "Hermione Granger and Prince of Serpents" in my pretty head.
