Disclaimer: I do not own Harry Potter or Mass Effect... I would buy them all but I am broke.

Summary: Harry Potter is not raised by his Aunt, instead he is raised by his Mother's Cousin and his friends on a little ship called the Normandy. Harry Potter Mass Effect Crossover

A/N: This Fic ignores the Storylines of Mass Effect 2 and 3. Don't get me wrong, I love the games, but Harry is raised by the crew of the original SSV Normandy SR1, so no Collectors and no Reaper invasion… at least not on the timeframe of the Games.


Harry and Hermione were sitting on the steps up to Astronomy Tower, playing with the settings on their Omni-Tools as they waited for the Astronomy class to start. It was almost the end of October, two months into class and a few days short of Halloween. Harry was just generally playing with his settings while Hermione was working on the programming of her defence drone. Harry had given her the base coding for the drone that he had gotten from Tali, allowing Hermione to set it up in her own way, which Hermione had named Athena.

Ever since the start of the year, and Harry's public use of his Omni-Tool, all of the Muggleborn and Muggle-raised began openly using their own Omni-Tools. Most of the teachers had reluctantly accepted the use of Omni-Tool in classes, as they can record the lecture, helped by the coerced edict by the Wizengamont to prevent prejudice against muggleborns and half-bloods. Snape had, naturally, not been accepting and had, on several occasions, cast spells at Puppy, all of which had harmlessly passed through the holographic drone, but the recordings of the events from Puppy itself, which Harry had taken to Professor Flitwick as his Head of House, had put Professor Snape under the intense scrutiny of the other three Heads of House.

Professor Sinistra arrived and escorted them up into the tower-top observation platform. Once the hatch door was closed, the sky was magnificent as the tower was isolated from any light pollution from the rest of the Castle. The Professor cast a Lumos and conjured a blackboard in order to give the brief beginning lecture.

"First off, homework." Professor Sinistra said.

Everyone walked up and handed her a single piece of parchment. Harry however, handed her half a dozen sheets.

"Mister Shepard, you were asked for a map of the inhabited Solar System." Professor Sinistra said.

"Yes, well I restricted it to the most important systems. Earth, Thessia, Palavan, Tuchunca and Rannoch, before and after the Morning War." Harry replied.

"Umm… okay." Professor Sinistra said confused.

"Professor, if I may." Hermione said, getting a nod from the Professor. "Thessia is the Homeworld of the Asari, Palavan is the Homeworld of the Turians, Tuchunca is the Homeworld of the Krogan and Rannoch is the Homeworld of the Quarians, and their AI, the Geth."

"Right, those races that the Muggles in the Alliance made contact with." Professor Sinistra mused. "Well, today we will be talking about the theoretical 'tenth planet' theory. The motion of the planets indicates that there is a gravitational force out beyond Pluto, one that has yet to be discovered."

"That would be the Mass Effect Relay." Harry replied. "I can give you all the details of the Relay if you want."

Abandoning the lesson, Professor Sinistra turned off the Lumos spell.

"Find and sketch three of the Zodiac Constellations." Professor Sinistra ordered and made a mental not to read up on the Astronomical advances of the Muggle World, maybe even see if she could access that 'Extra-nit' thing they have.


"Captain, the new intake is coming aboard." Tali said, still a little cold towards John and Liara over the Extraction Plan issue but keeping her voice quiet as Leanna was having a nap.

"Thank you, Tali, we'll be there in a moment." John replied.

Tali turned and left the Captain's quarters.

"What we have in this intake?" Liara asked.

"Five N7's and six N7 Recruits, one a human Spectre candidate. Six Asari Commandos. Nine Turian Special Forces, four Krogan Battle Masters and fifteen Quarian Fleet Marines. Including one called Kal'Reegar." Shepard replied.

Since Shepard had become a Spectre, there had been three more Human Spectres. The second was a former member of the Normandy crew who had left for N7 training and had later been selected as a Spectre. Since then it had been a requirement for Human Spectre Candidates to undergo and pass N7 training.

The Normandy had also become one of the main platforms to cross train elite Special Forces from the major races with their counterparts. The contingents being sent are on the Normandy for six months and then rotated back home to either help spread the skills learnt or to fill niche roles.

John and Liara went down in the elevator to the troop deck, which was connected to the shuttle bay by a ramp. Just off the elevator they were met by Tali, Wrex and Garrus.

"Welcome aboard the Normandy. I am Captain Shepard, and these are my senior trainers. You will become familiar with them and myself over the next six months. There is also a permeant Alliance Marine contingent aboard that will provide backup on any missions, where they are required. You are here as much to teach as to learn." John announced. "For the Humans, Turians and Asari, my Executive Officer Liara T'Soni Shepard will show you to your Quarters. Krogan report to Wrex for bunk assignments. Quarians, Tali'Zorah Vas Normandy will show you to special sterilised quarters."

The new intake broke up and Tali was standing at the back of the Normandy contingent, until she heard one of the Quarian Intake approach.

"Ma'am." A familiar voice was heard. "It's a pleasure to be aboard."

"Kal'Reegar." Tali exclaimed. "I did not know you would be here."

"I was told I was specifically requested, Ma'am." Kal replied.

"I don't have any say on who is in the intake, but I am very glad you are here." Tali said.

"So am I, Ma'am." Kal nodded. "I was slated to be part of the diplomatic security detail for the Embassy Staff that are arriving tomorrow before I was selected for this."

"Yes, it will be good for the Fleet to have an Embassy on the Citadel again." Tali confirmed. "Gather the others and I will show you to the sterile area."

Kal began to turn away when Tali spoke up again.

"My personal room is ultra-clean room environment, clean enough to go without suits for a shot period." Tali began. "Um… you are welcome to visit any time."

For a moment Tali was glad her mask hid the blush.

"Of course, Ma'am." Kal replied, with a slight smile in his voice.

"And Kal, in my quarters or when we are alone, it's Tali." She countered.

"Of course… Tali." Kal said before returning to the other Fleet Marines.


The Council Chambers were packed and buzzing with excitement as the Quarian delegation approached the podium. Across the gap stood the four members of the Citadel Council, Human, Asari, Turian and Salarian. The senior crew of the Normandy stood off to the side, Tali seeming to radiate joy with Kal'Reegar standing by her side. Bringing Kal on board had settled the remaining anger that Tali had with Shepard and Liara.

"It has been a long time since the Quarians last had a formal Embassy on the Citadel." The Asari Councillor said. "Given the trials your people have endured and the efforts of both specific individuals and your entire race have made to make the Galaxy safer and better place to live, it is my great pleasure to welcome the Quarian Embassy back to the Citadel and you have our apologies for the mistreatment you have suffered."

"We are honoured to return to the Citadel and the greater Galactic Community." The Quarian Ambassador said. "We hope to re-establish meaningful relationships with all races, as we already have with the Humans."

"We thank you and welcome you with open arms." The female Human Councillor said.

Her name was Sarah McKinnon and she had replaced Donald Udina six years previously when Udina had been diagnosed with a brain tumour.

"It is also my distinct pleasure to make the following announcement." Sarah continued. "Tali'Zorah Vas Normandy, please step forward."

Tali took a look around and got an encouraging nod from Shepard and a subtle 'come here' gesture from the Quarian Ambassador. Not having felt this nervous since she was on her Pilgrimage, Tali stepped forward onto the podium next to the Quarian Ambassador.

"Tali'Zorah Vas Normandy." Sarah announced. "You have show intense determination and sense of duty. You have demonstrated exceptional skill in both on and off the battle field, including risking your life under Spectre Shepard to save this very Council from the Rogue Spectre Saren years ago. Being invited to become the first Spectre for your race is both a great honour and a great responsibility. Tali'Zorah Vas Normandy, do you accept?"

Tali stood stunned for a moment. A Spectre? Her? Keelah, what just happened? Oh, wait, they are waiting for a response. What was the question? Oh yeah, did she accept becoming a Spectre. She glanced over at the Normandy crew. Shepard was smiling. Liara seemed stunned. Garrus was impress. Wrex was amused. Kal'Reegar was proud, she could tell from his bearing.

"It will be an Honour, Councillor. Yes, I accept." Tali replied.

"Congratulations. This is a momentous day for both yourself and the entire Quarian Race." Sarah said.

Tali walked back over to the Normandy crew.

"Keelah." She half whispered.

"Welcome to the club." John said.

"Congratulations, Ma'am." Kal added.

TBC…

A/N: I did not name the 'former Normandy Crewmember' who became the 'Second Human Spectre' as it can be Kaiden or Ash depending on who you saved on Vermire in your playthrough.
