Hoo boy this one was a fun one to write, I have two chapters for this already finished but I don't see me continuing it any further simply because the idea was very convoluted. I might pick it up in the future if more inspiration hit me but the entire idea extended into a multiverse of situations that just made my head hurt badly.

But enjoy what I have written.

Chapter 1: What happened?

Harry groaned as the bright light started to clear and he rubbed furiously at his eyes trying to clear away the spots he was seeing as he looked around to see himself standing on top of a roof the bright setting sun shining over him.

"...A world that loses its power will fade away into nothingness." A female voice spoke and Harry looked confused as a female figure appeared in front of him looking at the sun set. "If such is the fate of this world, then I shall return it to its mother's womb. The world must first die, for it to be born again..." She paused shaking her head sadly. "...That is the only way to salvation, as recorded in an ancient prophecy." She finished turning to face Harry who frowned in surprise… he recognised this person.

"The world will fall for its sins, and humans will all disappear... But, I don't want you to meet the same fate. I want to help you hold on to your life. To do so, I need to know your name. Will you tell me who you are...?" She asked and Harry looked extremely surprised by this considering he recognised her but couldn't think of her name off the top of his head.

"Harry Potter." He said and then caught a brief flicker of recognition in her eyes.

"I see, so your name is Harry Potter... As of now, your will to live shall be sustained. Believe in it...and live." She said and Harry frowned.

"I don't understand." He muttered in confusion.

"You may not understand right now... but please don't forget what you've heard here..." She responded trailing off and Harry's eyes widened as he saw a flicker of London being destroyed by flames and explosions.

"I am the nurturer of the next world. It is my duty to create the world that is to come... Now, I want you to say my name out loud." She requested as the glare of the sun lessened and Harry's jaw dropped as the name finally clicked into place.

"Hoshi?" Harry whispered and she smiled nodding her head ever so slightly.

"That's right...My name is Hoshi." She said tilting her head to the side looking at Harry before sighing. "...Harry. I won't shed another tear, not even at the world's end. I'd like to see you in the next world though..." She said and the images of the destruction of London started flashing at the front of his mind.

"Go ahead…" She said and paused again turning her back to look at the sunset. "Go ahead and wake up."

"It's time..."

That was two months ago. Two months after Harry appeared in the middle of the bar on Nos Astra surrounded by curious and shocked people. He exited quickly before people recovered and asked any questions.

"Two months I've been here." Harry muttered to himself walking over to one of the many balconys in Nos Astra. He leant against it looking over the edge holding a vial of clear liquid in his hands before sliding it into his pocket. "Two months I've been here and no word about any of my friends." He muttered looking at the datapad that had the information he was sent to collect. "As beautiful as Illium is, I need to escape, to find my friends so we can get back to where we were meant to be." He continued muttering under his breath. "I better hand in this information. Liara is going to want to see it." He muttered pushing himself away from the Balcony. Liara had proved to be his saviour when the mercenary groups focused on him, intrigued by his appearance. She had her contacts direct the information he gathered when looking for anything he recognised and lead him straight to her.

Harry of course bit the bait hook line and sinker. Lead straight to her, she questioned him about what his abilities were.

This was his first introduction to Biotics. He had been abrupt, disrespectful and annoyed at being manipulated by her and had turned to leave. She had with barely a whim lifted him into the air and slammed him into the wall a look of annoyance on her face. Harry had been shocked but calmed down. He agreed to tell her on the one condition that she didn't pass on the information to anyone.

"That is going to be difficult, I believe all my conversations are being monitored." She had explained and Harry had just smiled removing his wand from his pocket and giving a simple gesture and muttering a 2 word Latin spell and a blue dome erupted around the two of them covering the room. Liara had heard several electronics blow, even in places there weren't any and she smiled knowing some of the bugs must have been fried by whatever this was.

"Magic." He responded as if it explained it all. "You wanted to know what I was, how I got here, it was all down to magic." Harry responded as she released her biotic grip on him and let him land easily on the floor. He had paused, rotating his shoulder to work out a slight pain before moving over to the chair as the bubble faded from view. "We can talk now, no need to worry about anyone overhearing us." He said.

Liara had manipulated him into finding her but she had been honest about it. She needed assistance to find a person who had been captured by the illusive Shadow Broker, a man who had his fingers in more pies than anyone in the galaxy, the guy reminded Harry briefly of Kane.

Harry walked up the stairs to her office, the door was shut and the Receptionist, who for the life of him, Harry couldn't remember her name was sitting there looking slightly, bored. "Oh Mr. Potter." She spoke in surprise not hearing him come up the stairs. "Liara is in a meeting with Commander Shepherd at the moment and doesn't wish to be interrupted." She said and Harry nodded moving over to the desk and sitting on the edge, turning himself to look at her.

"That's fine, I'm in no rush, the information doesn't need to be acted on for a while yet." Harry explained and the receptionist nodded.

"So you were successful then?" she asked and Harry nodded.

"Thanks to the information I was given I was able to get hold of it with the person being none the wiser." Harry explained and she smiled as the door opened and a Human, a Turian and a Quarian walked out the room. The Human, which Harry assumed must be Commander Shepherd paused a moment studying him before nodding his head to the Receptionist and him and leaving. Harry watched the three leave before pushing himself off the desk. "I should go see her now, you how she gets when having to wait for information. I hit my quota of being thrown around like a ping pong ball quite a while ago." Harry said and she laughed gesturing for him to enter the room.

"Hi honey, I'm home." He called out as he walked into the room with a goofy grin on his face. Liara was sitting at her desk going over something on the computer, she looked up and frowned at him.

"Must you do that Harry?" She asked her voice calm and cold as ice.

"Ok not the reception I wanted. Guess things with the love of your life didn't go as planned, I figured you two would be going at it like rabbits now that he was back from his 'death' and all." Harry commented and Liara frowned.

"How did you know about that?" She asked.

"What can I say, I have my ways of getting information even from tight lipped people. They have a habit of broadcasting their thoughts in a way that I can pick up." He said and she glared at him her eyes starting to glow.

"Your reason for being here… quickly!" She snapped and Harry raised his hand in a placating manner.

"Ok, ok jeez calm down M'dear." He said quickly. "I got the information you wanted." He said removing the vial of liquid from his pocket and sliding it to her. "It also worked as a great test for the Veriatserum." He explained and Liara lifted the vial looking at the crystal clear liquid.

"I have to admit, when you asked for those ingredients I didn't expect it to work." She said and Harry smiled.

"Oh you have little faith in me? I'm hurt." Harry joked as he retrieved the data pad. "There is going to be a shipment on Omega in the next couple of days. I have no idea what that means but from the frown that just appeared on your face, it can't be good." He said and Liara noddded her head.

"Omega is a lawless hell, if the Shadow Broker is making a drop on Omega its going to be harder to get the package than I anticipated. Omega is run by another Asari, one called Aria T'Loak, she is older than I am and ten times as vicious when she needs to be. She knows almost everything that happens in Omega." Liara explained and Harry frowned.

"Awfully risky for the Shadow Broker to make the drop there then isn't it?" He aksed and she nodded.

"If the Shadow Broker is willing to risk dropping the information there then it either means that she is working with him or he is getting desperate." A smile tugged at her lips. "I think I'm getting close." She said and Harry raised an eyebrow.

"Don't let revenge be your only motive for doing this Liara, it will destroy you." Harry commented as he slid the datapad to her.

"He will pay for what he has done. That I can guarantee you." She responded and Harry sighed and gave up.

"What do you want doing with this intel?" He asked and she looked thoughtful standing up moving towards the window.

"I'll arrange a shuttle for you, take it to Omega and intercept this package, no doubt Aria will know what you are up to when you arrive but try to keep her out of it. Find the drop, take the package and return here." She said.

"Right now that I know what I'm doing what have you discovered about my associates?" Harry asked, standing and moving over to the window overlooking the Trade Sector.

"The ones you know as Kane and Yuri have not been located, not a single word about them. I have heard information about Tanya Adams, Natasha Volkova and Zhana but I am still trying to locate them." Liara explained and Harry nodded.

"Thank you, this is the first piece of information I've had on them." Harry said and Liara smiled slightly.

"You have been doing me a great favour Harry, I am happy to repay my debts." She said and Harry nodded his head.

"I should get some rest before I go on this job." Harry said and turned to leave.

"I will have the pilot ready by morning Harry." She said and he nodded and waved his hand in farewell before walking out the door.

"So not bounced around then?" She asked as Harry walked out the door and stopped to look at the receptionist.

"Not this time, came awfully close." He responded as he went to walk away. "I shall speak to you soon." Harry said continuing to walk down the stairs.

"Maybe next time you'll remember my name." She called out teasingly and Harry stumbled forwards caught completely off guard almost falling down the stairs.

"Perhaps I will, perhaps I won't I like to be unpredictable." Harry responded in the same tone recovering quickly and moving down the stairs and out of sight before she could respond.

The next morning came around a lot quicker than Harry anticipated. It had taken longer for him to get to sleep the excitement of travelling into space and finally getting off of Illium was rising up inside of him. And although he knew he would be back with the information in a couple of days, he was still glad to see a change in location.

He arrived early to the ship the pilot going through last minute checks to make sure everything was ready and nothing disastrous would happen. The pilot, a human turned and looked at him. "You must be Harry Potter, I'm Fred." He introduced and offered his hand. Harry shook his hand. "Just a few more moments until we can set off, wish we could be going somewhere a lot nicer than Omega though." He said and Harry laughed.

"Any particular location?" Harry questioned.

"Now that Saren's base and the Geth have been cleared off of Virmire, they have some lovely beaches to relax on." He said and stepped out of the way so Harry could get in to the ship. "Take a seat inside I should only be a couple more seconds." He said and Harry nodded his head entering the ship.

The take off had been smooth and soon they were in space, Harry stood watching through one of the side windows as Fred begun plotting the course to take to the Mass Relay.

"So I hear this is your first time in space." He said and Harry looked over at him and smiled.

"Not my first time but it will be my first time through a Mass Relay." Harry explained and Fred looked at him in surprise.

"Really? You were born here?" Fred asked and Harry shrugged.

"Sure, why not." He said not wanting to explain it.

"Anyway, the first trip through the Mass Relay is always the best." He said and Harry took a seat as he saw the large Relay up front. "Just give me a few more seconds to plot the course." He said and the console started beeping. Harry frowned turning to look at Fred.

"What's that?" He asked and Fred frowned as he slid another holoscreen into view.

"Sensors are picking up a ship, a very big ship." Fred said tapping away trying to analyse it. "It's on an intercept course."

"Hostile?" Harry asked and Fred shrugged.

"I have no idea, personally I don't plan on sticking around to find out." Fred said and switched back to the NavScreen. "Preparing for Jump." He said and after a few more seconds they were gone.

I originally had the idea for a Mass Effect 1/Harry Potter storyline for the Wargames series. I liked the idea a lot but could never get it to work properly. Then of course Mass Effect 2 came out and I've played through it and the storyline that goes with it for this crossover just works so much better. I hope you enjoy.
