AN: So, I was given a challenge to write a HP/MLP crossover story. After thinking about it my brain wouldn't leave me alone, so I decided to go ahead and accept the challenge. The challenger was one of my reviewers by the name ShiroHollow96. So thankyou Shiro for giving me this challenge. I'm not sure how long this story is going to be, but it'll be fun all the same.

I am going to point this out. Harry will never return to his world. He will grow up and stay in Equestria. Sirius and Remus won't be forgotten. More to come later on that issue. Anyways, onto the story.

I am not going to write down the whole chapter of Harry being dropped off, so this is mostly Celestia's point of view as she observes Dumbledore, Minerva and Hagrid.

Chapter 1: Through the Portal

Celestia was in one of the secure rooms of her palace. She looked at the large mirror in front of her. Her old mentor Starswirl was the one that made the mirror. It was a portal to other worlds. Generally, it went to the parallel human world, but there was a way to make the portal visit other places as well.

Celestia knew there were many parallel worlds and she wanted to visit one of those worlds. She charged her magic and shot it at the mirror to charge the magic. She walked through the portal cautiously and found herself in a darkened park. She looked up seeing the stars and moon and idly wondered if this moon was the same moon her sister Luna was on.

She shook her head sadly as cast a spell to make herself invisible. It wasn't perfect, but it served its purpose for exploration. As she walked, she came to a neighborhood. All the houses seemed to be uniform and a bit bland in her opinion. What really caught her attention was the magic she felt being used nearby.

Curious she made her way over and saw two people talking. An old man that reminded her of a humanized Starswirl and a strict looking woman. She about to move in close when she heard a loud roar. Startled she ducked and covered behind a neighboring hedge. She observed a mechanical bike with a huge man on it. She pressed down her ears when the man started talking before, he was quieted by the woman. It wouldn't due to wake up the neighborhood.

She settled in to listen as they talked about this Harry Potter infant that defeated a dark lord. She was horrified at what they said and implied. As Dumbledore sat the sleeping infant on the steps, Celestia knew she had to do something. She moved in as the two men left. She knew the old woman was hesitant to leave the baby behind.

"Sorry to eaves drop on you and your cohorts, but I have a better idea then to leave an infant on a doorstep." Celestia said showing herself to Minerva. Celestia held her head high as she looked at the stern woman.

Minerva gasped and whirled around to face the intruder with her wand out. "Who are you?" she said prepared to defend Harry. She crouched into a dueling pose.

"I mean you and the infant no harm." Celestia said firmly. "I overheard you and the two men talking and I feel I can better protect him. I am not from here and no one can find me even if they tried." Celestia spoke. She was prepared to fight if it came to it. Abandoning foals is one crime that was strictly enforced. "Where I come from, abandoning a foal would warrant life imprisonment or death." She said coldly as she walked towards the young one. She felt a pull towards him that she couldn't ignore.

Minerva studied the creature before her. A beautiful unicorn with wings. "What are you? You look like a unicorn with Pegasus wings." She asked fishing for more information.

"I am an Alicorn from the land Equestria." Celestia responded. "Tell me, why is he being abandoned. What happened to his parents." Celestia asked wanting to fill in the details she'd missed.

"He is Harry Potter. His parents were James and Lily Potter. They were killed by the dark lord V-v-voldemort. He is the only survivor of a curse that will always kill. He is being left with his mother's sister because of the blood protection she can provide." Minerva said reluctantly.

"So, you would just leave him there without informing his aunt? It is a cold night. What would stop him from freezing to death or wandering off when he wakes?" Celestia fired off as the thoughts came to her. "What would you do if his aunt didn't want to take him in? Leaving him here like this is irresponsible, not to mention dangerous. Anyone could walk off with him or he could get injured or die from the elements." Celestia growled as she stalked towards Minerva.

Minerva tried to come up with arguments to Celestia's questions but couldn't. She sighed in defeat. "You're right and you're only saying what I've been thinking." She sighed relaxing and putting her wand back in her arm holster.

"I don't want to leave him here, but if he stays in our world, nothing could keep him safe…" she said.

"There is another way and I can promise that he'd be in a loving home." Celestia said gently as she realized Minerva wasn't to blame. "I could take him back to my world and raise him as my own son." Celestia said as she moved over to the infant and nuzzled him gently. He didn't stir. He was obviously exhausted.

Minerva watched the interaction silently. She felt she could trust this Alicorn. "Swear on your life and magic that you will love him and keep him safe and happy." Minerva said making her decision.

"I, Celestia, ruler of Equestria swear to take Harry Potter as my son. I swear to love him and keep him safe and happy as long as he lives." Celestia said solemnly. There was a flash of white light as the vow took.

Celestia picked up the sleeping infant in her magic and held him close to her chest. She cast a warming and sleeping charm on him.

"Did his parents leave him an inheritance? Is there a picture of them so he knows what his parents look like?" Celestia asked as she started planning.

Minerva nodded. His parents are well off, but we'd have to go to Gringotts for his inheritance. "I would advise that you request temporary asylum at the Gringotts bank. They can set you up as his guardian. Are you able to shift into a human form?" Minerva asked.

Celestia nodded. She floated Harry into Minerva's arms, so she could shift into a young woman in her late 20's. She color changed her hair into a more natural blonde color. "Will this do?" Celestia asked.

Minerva gave a nod of approval. "Grab my arm and I'll apparate both of you to outside the bank. We will have to walk in though." Celestia smiled and gently grabbed Minerva's arm. A moment later they popped away.
