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.

"A Quarian, a Taurian, an Asari and a Krogan walk into a bar." Hannah Shepard joked as the group walked into the Leaky Cauldron.

"The punchline to that would be amusing." John Shepard replied.

Hannah felt a tugging on the leg of her Jeans, and she looked down to see Leanna.

"What is it, sweetie?" Hannah asked.

"Oma, I'm an Asari too, so shouldn't it be two Asari?" Leanna asked.

"Oh, I know that, sweetie, but I was making a reference to some old Human Jokes." Hannah replied.

Leanna's forehead wrinkled as she thought hard about that for a moment.

"Ok, Oma." She said after a second. "I thought you might have forgotten."

With that, Leanna skipped off to her beloved big brother, slipping her hand into his as they walked through the pub. The group had been attracting attention mainly due to the number of Non-Humans amongst the group amongst a purely human crowd.

Harry had received a letter, forwarded through the Extranet, that invited him to attend Hogwarts. Knowing that his birth parents had attended the school, John could not deny Harry the chance to learn there, so he had set the Normandy on course for Earth and had called Hannah Shepard, who had been promoted to Admiral several years prior, to let her know that they were headed back and why.

The group walked out of the back of the pub to a walled courtyard. Hannah pulled a box with a wire attached probe.

"We can thank Miss Vas Normandy and a few of her friends for this." Hannah said.

Hannah put the probe to a section of brick that looked like the face of it had broken off and pushed a few buttons. Suddenly the bricks started to shift and formed into a portal into a street that looked like it was out of the eighteenth Centaury.

"Looks like the Dark Energy Modulated Oscillation Network works." Tali said.

"It needs a better name, I think." Liara said.

"I don't know." Wrex replied. "Little Tali's Demon has a good ring to it."

"Well, let me know if it ever needs calibration." Garrus joked.

"No one calibrates Reegar but me." Tali shot back before she could help herself.

"You called it Reegar?" John asked.

"Keelah." Tali said, covering her faceplate with her hands.

"Aunty Tali, why did you name it after that nice guy who keeps calling you 'Ma'am'?" Leanna asked.

"Come on, Smurf." Harry interrupted. "Let's go visit the bank and then we can go look at the bookstore."

"Oh… books." Leanna said excited. "Are they data-pads or paper ones?"

"Let's find out." Harry said as he led Leanna away from the group.

John and Liara followed their children, John's arm around Liara. Garrus and Wrex chuckled as they followed. Hannah approached Tali and put her arm around the Quarian, who was constantly repeating 'Keelah'.

"Come on, Tali." Hannah said in her mother's voice. "Tell me about this Reegar person."

The way Hannah talked to Tali reminded the Quarian of her long dead mother. The emotions that it stirred up, and the care in the older woman's voice made Tali start talking before she really thought about it.

"His name is Kal'Reegar. He's a Migrant Fleet Marine…" Tali began.

Hannah kept her comforting arm around the talking Quarian as they walked down Diagon Alley after the rest of the Normandy crew.

Harry sat on the Hogwarts Express, watching a recorded video message from Reli'Herra on his Omi-tool. He was listening to the message in the original Quarian, without the use of his translator. When the door opened, he paused the message, with Reli's head floating over his Omi-tool, and looked up to see a girl around his own age with busy brown hair.

"Do you mind if I sit here?" the girl asked.

Harry simply nodded and finished listening to the end of Reli's message as the girl sat down. Once the message ended, Harry closed out of his Omni-tool.

"Hello." The Girl said. "My name is Hermione Granger. I see you know a Quarian. My parents have one on Pilgrimage working for them at their Dental Practice. She has repaired most of their Dental equipment and completely re-wrote their Operating System which made it five times faster."

"She's a friend." Harry replied. "My name is Harry Shepard nar Normandy of Clan Urdnot."

"That's how she introduced herself, except for the Clan thing. Nori'Tenos nar Helios." Hermione replied. "Mostly she just gets called Nori. So, why do you introduce yourself like a Quarian?"

"I was raised on a spaceship, called the Normandy." He replied. "My dad is the Captain; his Wife and XO is Asari. His Chief Engineer is Quarian, his Gunarry Officer and best friend is Taurian and his 'ground combat specialist' is a Krogan."

"Wait." Hermione said. "Normandy. Nori told me about a famous Quarian. Tali'something Von Normandy."

"Tali'Zorah Vas Normandy." Harry corrected. "Von is someone with a weak bladder. Aunty Tali help raise me. She did her Pilgimage under my dad and then decided to stay on as his Chief."

"Was she that Quarian in the message?" Hermione asked.

"No. That was Reli'Herra nar Neema." He replied. "She's not much older than us. Only got her first Environmental Suit a few months ago."

They spent the rest of the train trip discussing Quarian culture.

"We all set, Lieutenant?" Hannah Shepard asked.

"All set, Admiral." The Alliance Marine Lieutenant replied. "An entire Platoon is ready."

"Lieutenant, begin the operation." Admiral Shepard ordered.

Twenty-six minutes later the entire Ministry of Magic had been secured by the Alliance Marines and the Wizengamont, which had been in session, had been detained in Wizengamont Chambers. Hannah Shepard entered the Wizengamont Chambers with the Lieutenant and two Troopers as body guards.

"How dare you." One of the members of the Wizengamont declared and shot a spell at Hannah.

One of the Privates stepped in front of Hannah and the spell dissipated over the Private's Shield without effect. The other Private raised his Assault Rifle at the offending Member.

"Stand down." Hannah ordered to the Marines before turning back to the Wizengamont Members. "That was very stupid. Now, let us get this show on the road."

"You are in violation of the Statute of Secrecy." The Minister of Magic shouted.

"How moronic are you?" Hannah asked. "Firstly, we are not under your authority or subject to the Statute. Secondly, the Statute is in violation the founding principles of the Wizengamont. Thirdly, we have always known about existence of the Magical World. We just let you have your delusions."

There was dead silence in the chambers for two whole minutes.

"What do you want then?" Dumbledore asked.

"Restore full equality to all Magicals, regardless of supposed Blood Status." Hannah informed them. "Drop all the Blood Status restrictions on jobs. Allow any Magical to freely leave the Magical World without any attempt to change their memories. And for God's sake, no more attempts to Obliviate Muggles. Let us deal with it. We're better at it and sick of having our people Obliviating your Obliviators."

"Why now?" Dumbledore insisted. "If you always knew about our world, what's changed to prompt this?"

"My grandbaby's heading to Hogwarts." Admiral Shepard declared. "He will be treated as an equal or I will personally shit-kick every single one you down one side of the deck and up the other. Do you understand me?"

"Yes, Ma'am." Every member of the Wizengamont replied, instinctively reacting to her command voice.
