Harry potter: Another kind of magic.

Harry had always believed that his parents were Lily and James Potter. However, one night in his first year at Hogwarts School, he finds a mirror that shows him his parents - but they're not who he thought they were.

It had been a month now since Shining Armor and Princess Cadance got married. The newly married couple were in Canterlot Castle that day, while Princess Cadence coming out of the Castle's Infirmary after learning that she was pregnant with her husband, and also learning from the best doctor there was that her first born would be a boy.

However, she soon came across a room that been calling her for a while, each time she passed it in fact. Today, she was finally going to enter that room along with Shining at her side.

"This is the room that Princess Celestia told everyone never to enter for any reason because of a mirror inside." Shining reminded his wife.

"Why don't we go through it? Auntie won't know." Cadance pleaded with her husband.

Regretfully, Shining Armor nodded, following his wife through the mirror, soon feeling like they were falling. They both landed in a court yard outside a huge mansion, where two people were stood looking distressed, until they caught completely off guard by the ponies' arrival.

"How did you get here?" The woman asked, having red hair and emerald green eyes.

"I am Princess Cadance and this is my husband, Shining Armor. We came from another world. May I ask, who are you?" Cadance responded.

"I am Lily Potter and this is my husband, James Potter. I can tell you are on the light side rather than the dark side as our ward allowed all three of you in." Lily replied, much to Cadance's surprise.

"How do you know?" Princess Cadance asked in shock.

"The wards that have been cast over our property can tell how many are present here." James told them.

"I see. What is the matter with you two?" Shining asked.

"We cannot have an heir for the family. After our latest escape from our enemy, Lily was cursed." James told them, holding his wife's hands in his.

Suddenly, Cadance understood why the mirror had been calling her all this time.

"When my son is born, he can become yours." Cadance offered, much to Shining's surprise but also his acceptance.

"Are you sure about that? We're complete strangers!" Lily asked.

"I am. If something were to happen to you, we can still look after him and you would have a child to call your own." Cadance told them.

"Well, when is your son due?" Lily asked.

"At the end of July." Cadance responded.

"That is a lot of time. We'll make you officially trusted associates of the Potter family which will allow you to access the family vault." James told them.

"Thank you." Princess Cadance replied with a smile.

Over the time, the newlywed couple became close friends Potters and some of the Order, but kept it secret from Dumbledore and Snape. Eventually, they assisted the Order on a mission, the mission where James and Lily were fatefully hit with the Killing Curse. The two ponies secretly took James and Lily's identities so no one would be any the wiser, expect for those on the mission with them - Sirius Black, Remus Lupin, Minerva Mcgonagall, The Longbottoms and Arthur Weasley.

It was now 31st October 1981, a full year after Harry was born as the child of Cadance and Shining under the guise of Lily and James Potter. Disguised in her red haired and green eyed human form, Cadance was in the nursery with her infant son and her husband, also in their human disguises. The real Lily and James had chosen Harry to be their baby's name a long time ago, and it was honoured.

As far as most people knew, including Lord Voldermort, they were James, Lily and Harry Potter.

While she tried to settle her son, Cadance found herself missing Equestria. The pony world was much more peaceful than this world, even if her Aunt Luna was watching over her.

"Hush now, mama is here." Cadance told her baby, rocking his crib gently as Shining went downstairs.

"We are always watching you, my dear niece." Princess Luna's voice reminded her.

"Lily! It's him! Get Harry and get yourself out of here!" Shining called up to her from the stairs.

"Why, oh why must you betray us to this monster, Peter?" Cadance thought to herself as she picked up her son, only to be face-to-face with a non-human like face of a man.

"Stand aside, you silly little girl!" Lord Voldemort demanded.

"No! I won't let you have him!" Cadance retorted.

"Then I will have to kill you to get to your son! I will not let him be my downfall!" Lord Voldemort told her, his red eyes narrowed dangerously at her.

Cadance's resolve only steeled, clutching Harry tightly in her arms as she stared him down.

"Avada Kedavra!" Lord Voldemort said in a cold voice as a green light shot from the tip of his wand - and disappear against a dark blue magical shield.

"You shall not harm my niece or my great-nephew you monster!" The thundering voice of a dark blue Alicorn addressed the evil wizard as she emerged from the shadows.

"Who are you to try and stop me?" Lord Voldemort laughed at the new figure in the room.

"I am Princess Luna. I am here to protect my family and I will teach you to fear the night." Luna replied, calm but firm as her eyes flashed with power.

"I will not fear a silly horse - I am the greatest dark lord to ever walk this land! Now be gone!" Lord Voldemort told them laughed, going to try his spell again. "Avada Kedavra!"

A bolt of magic came at them as before, aimed towards Harry, but this time it rebounded on a pink shield - the same pink as Cadance's pelt - firing back at Lord Voldermort with twice the strength.

"No! This cannot be happening!" Lord Voldemort cried as he disappeared from his spot.

Before Cadance could even relax, she found herself wrapped in yellow magic and ripped from her son, her son being placed back in his crib while she was taken back to Equestria. This was Celestria's magic so Cadance knew she was in trouble.

"I am very disappointed in you, Cadance!" Celestria told her as she approached.

"I know, Aunty, but I wanted to see what was behind the mirror. It kept calling to me." Cadance explained.

"I have moved it far away from here and protected it with a spell. No pony will ever go near it again without me knowing." Celestia told her sternly.

"I also need to tell you something, Aunty. It's important." Candace told her aunt.

"And what may that be, Cadance?" Celestria asked her with cautious interest.

"I am a mother and my son is still in that world! My first born is still there!" Cadance told her, pleading with her.

"I am very sorry, Cadance, but I will keep watch on him. He is needed very much in that world." Celestia told her with sadness in her voice.

"Why can you not bring him here now, Aunty? He is a pony like us! Not a human!" Cadance pleaded more, more worried than ever.

"He will return when the time is right, but for now tell me what happened in that world." Celestria offered.

Cadance told her aunt about her time in that human world and about how magical it was, despite the brewing war.

"Cadence! I am so happy you're okay!" Shining said to her, running to her as he entered the room but stopped when he didn't see his son.

"Your son is needed there. He will save their world." Celestria said to them as she left the couple together in the room.

Back in England, where Harry had been left, Princess Luna was looking over her great-nephew. She knew that he would be a celebrity in this world, destined to defeat the Dark Lord who dared to try and kill him and her niece.

"Who are you? Where are Lily and James? Why are you holding my godson?" A male voice asked her, revealing a man standing in the doorway with his wand aimed straight at her.

"I am Luna and they are not here to raise him anymore. Who are you?" Luna responded.

"I am Sirius Black, Harry's godfather, friend and brother in all but blood to James Potter." Sirius Black said to her with his wand still aimed at her.

"I am only checking that he is unharmed. I must leave him in your care, but know that you are always being watched." Luna said to him, handing Harry over to Sirius and disappearing with her own magic.

"Hand him over, Black." Another mans voice said, belonging to the huge figure that had now appeared in the room.

"Where is he going to go, Hagrid?" Sirius snapped.

"I can not say because of Dumbledore's Order." Hagrid told.

"Take him on my bike and bring it back to me. I have a traitor to find." Sirius said, handing Harry and the key to his flying bike to Hagrid.

"Thank you, Sirius." Hagrid nodded simply.

With that said, Hagrid left Sirius alone in the mansion, taking the flying motorbike to Surrey, to a road known as Privet Drive, where there were several people waiting for him.
