Chapter One

Imagine a portkey, now imagine taking a portkey along with a roller coaster ride, multiply that sensation by thousand and you will get the sensation which he had to endure when he had been lifted off his feet and thrown through time and space by that cursed bed sheet.

After a subjective eternity his feet touched solid ground. His head was spinning. He sat down and tried to clear his head. He recovered and looked around. It appeared like he was in a city. There was a stadium quite similar to a quidditch stadium to the north.

"At least, no graveyards this time" he muttered to himself.

The hallows had appeared beside him but without the bed sheet. He collected them.

The city was dark and dreary like the cave. It felt like a feeling of dark magic permeated the air.

He heard footsteps, looked around and saw a buff guy walking towards him. It was dark to make out any details but the guy was muscular and about his height. It would be just his luck if this guy turned out to be a mugger.

"Do you need any help? Man you should be inside tonight" he spoke with an American accent. As he came closer Harry realized that he was wearing large glasses. Correction a nerd mugger.

"Uh-huh could you tell me where I am?" Harry asked him in what he presumed was an innocent voice.

He looked at Harry in a peculiar way and said "You are near the soldier field".

"Could you tell me in which state I am"

He sighed and said "Man You picked a bad night to get drunk".

He was getting a bit impatient now. "Why? Is Vader coming to town tonight". Hermione had forced him to watch the star wars movies.

He got flustered, spoke slowly as if looking for a reason "It's Halloween".

He should have known, Halloween is his time of the year .Trolls, Petrified cats, assassination attempts and what not. Harry figured he was venting his frustration on the guy. So to make nice he introduced himself

"My name is Harry".

The guy perked up and looked at him curiously. "I guess all Harry's are crazy. I am Billy. I must get a move on. Get behind a Threshold tonight".

He walked off.

"I guess all Yanks are crazy and what the heck is a threshold" Harry yelled loudly towards him.

Harry started walking in the opposite direction from that guy. Within five minutes he saw a big building, a museum if the architecture was anything to go by. Harry saw a board that stopped him cold in his tracks.

It read

Field Museum

Chicago

U.S.A.

"Great just great" Harry had never been to the U.S. in his life. Here he was in Chicago with the hallows for Companionship.

He tried to get a feel for the magic in the air. There was a trail of magic that led to the inside of the building.

He followed his instinct and went inside. The glass of the door had been smashed. He went inside.

Thunder rumbled Lightning flashed, Harry shrieked like a girl and fell flat on his ass. He tried to control his heart rate.

"It's just a skeleton Harry. No dinosaurs coming to eat you tonight" he spoke to himself. There standing in the gallery was an impressive skeleton of a T-REX.

The entire museum lay ransacked. The exhibits destroyed, Artifacts strewn around .He went upstairs. He walked in on a crazy scene.

A really tall guy wearing a ridiculous coat was lying on the floor. His hands and legs were bound with manacles.

He was clearly in pain. An old man was crouching besides him, holding a knife to the man's stomach.

"I have dreamed of this for a long time boy" and caressed the cheek of the man on the ground with his knife.

It was creepy. Harry looked around for movie cameras but they were not there. Then the old man took the knife to the guy's stomach.

Harry rushed into action. He drew his wand and shouted his signature spell

"Expelliarmus"

Scarlet light rushed from his wand, struck the old man head on, lifted him off his feet and threw him into the wall. He slumped to the floor. "

The tall guy on the floor looked at Harry and said "My faith-o-meter just went from zero to thirteen Gazillions in five seconds".

He then looked at Harry's wand.

Poor muggle Harry thought. He has been clearly traumatized.

Who would not be, if a crazy old man tried to do creepy things to you in a museum on a Halloween night.

To give him a reasonable explanation for the spell Harry said "I know martial arts and stuff".

The guy laughed and then fainted.

Harry went to the old man. He was alive. Harry stunned him for good measure and then bound him in conjured ropes.

He then went to the tall man passed out on the ground. He cut the manacles bounding his hands and legs. He then enervated the man.

The guy came around in about ten minutes. He was a middle-aged guy with a hawkish face. He had a lot of scars. Harry noticed that his left hand had been burnt to a crisp.

"Thank you for saving my life. I had almost given up hope "He said. His voice was deep and he spoke in a gentle tone.

"Could you explain what was happening here? I don't like hitting old men"Harry said

"Long Story short. This old man Cassius was part of a group of demons known as blackened denarians. They are killers, terrorists, sociopaths all rolled into one. To be one of those demons you required a cursed coin. Cassius lost his while fighting me a couple of year ago. So he was just exacting his revenge on me"

Harry figured that the guy was telling the truth but demons were an alien concept to him. Could this guy be lying to him? He shelved the question away for the future. He found the guy looking at the old man very intensely

"I told him I will kill him If I meet him again".

"You are not killing anybody. Mate."

"He is dangerous. He needs to die".

"Give him to the Aurors.".

"Aurors?" Dresden asked .

"Wizard police or whatever you call them around here".

"You mean Wardens...Hell's bells I am a warden myself. Okay I can do that."Dresden said.

He was looking at my wand curiously.

"Interesting foci"

Harry winced a bit. Had he recognized the elder Wand?

Then he lifted an honest to God wooden stick with tattoos and said "I prefer old school".

A staff, a freaking staff. How come Hermione never told him that they use staffs in the United states.

They were not getting anywhere like this. If he was an American Auror, maybe he could help Harry

"I am Harry Potter" The guy looked at him like he was crazy or something. Is Harry the name of the devil in Chicago?

He then smiled and said "Nice to meet you. I'm Harry"

"Look I have had a very bad day. It would be appreciated if you don't test my patience".

He chuckled and spoke "All right, No need to get testy. I am Harry Dresden. So what do we call each other? We just can't go around calling each other Harry"

Before he could say anything Dresden said "I get it. You are the Harry with the small stick and I am the Harry with the big stick"

Harry figured why that old man would have wanted to kill him. The guy is annoying.

"So what's going on around here, the city kind of feels too cheerful or something"

The man gave him a smile and said

"Necromancy and black Magic, the necromancers are going to do a ritual in sometime. It will give them unlimited power. The ritual will strip the life force of every living thing around ten miles. Thousands of people will die. I need to stop it."

He paused for a second and continued

" Man, I keep biting off more than I can chew"

Harry did not know if Dresden was serious or not. He then looked at the guy and said

"You are actually telling the truth huh. Pretty Crazy stuff. I will help"

Dresden retorted "It's too dangerous even for me".

Harry smirked "I was born for dangerous. You haven't seen my punches yet"

Dresden paused for a moment and said "Yeah I guess. You took out Cassius with a focused and powerful strike. Anyways I need a drummer".

Harry said "I look like a rock star but I don't do drums".

"Ha ha ha very funny but Mr. Harry with the small stick but we need a necromantic field around ourselves to get close to the ritual and to get a zombie running you need a constant beat.".

During this whole talk Harry Realized that Dresden was averting eye contact and looking the other way. Lightning flashed illuminating the T-Rex skeleton. Dresden was looking at it with an unnerving intensity.

He then asked Harry to wait and went outside. He returned a couple of minutes later with an Honest to god polka set,handed it to Harry asking him to play. it,Harry simply charmed it to play. It wasn't much more difficult than making a pineapple tap-dance across the table.

Dresden's ability to annoy him reached another notch when he asked Harry if he could do God Save the Queen.

Dresden did some stuff with the huge cables making them into a circle around the Dino skeleton, Then he began working his magic.

When Harry saw the result he whistled. Dresden yelled in a loud and boisterous voice

"Ladies and Gentlemen I give you the World's first Dino zombie."
