DarkPriestess66: I've decided to update with or without my Beta Reader, so if you don't like it, not my problem.
On the other side of the portal, three humans were waiting for the arrival of the new ambassador of the ponyland of Equestria and where the Boy-Who-Lived disappeared too along with his half-sister.
"Just how was this pony supposed to get here?" Arthur Weasley asked, when Dumbledore and Fudge approached him to open his house a strange ambassador, he agreed only out of curiosity.
"I'm not sure." Minerva replied "All Albus would say on the matter was their choice was familiar to us, but she had grown into her power since the incident occurred."
"But why must we meet here of all places not at the cauldron." Snape sneered out as well.
Just as the deputy headmistress was about to answer, her eyes grew wide in surprise as a swirling portal opened.
Harry tumbled out of the portal and landed in the grass, he looked up and saw the group of humans staring at him.
Michi walked out of the portal with a little more grace then her brother, "Next time, do not run."
Harry turned to her, "But you told me to hurry." He looked back to the humans, "Hello everypony, it's good to meet you." he smiled and waves his hoof to them.
"But I did not tell you to run." Michi retorted, before turning her green eyes on the humans, "Greetings from myself and my honored Aunts: Princess Celestia and Princess Luna." She then bowed her head, "I am Princess-Ambassador Dimension of Equestria."
The trio of magic users turned to the pair of alicorns and just stared at them. After a couple of seconds, the older mare spoke first. " Greetings you highness it's a pleasure to finally meet you." she said with a slight courtesy.
"Honestly, this is not my first visit to this world." Michi answered she was starting to enjoy this.
The dark haired stallion looked at her. "This is not but this is the first for us and i must say this is unique experience."
Severus Snape stared at the speaking mare, why did she seem so familiar to him. "Merlin's Beard."
Harry turned his head to the potion master "Whose beard? And don't stare at my sister like that."
Michi vaguely remembered stories of Merlin told to her by her stepfather, "Merlin is their version of Star Swirl."
"Minerva, you do not recognize her?" Severus questioned
Minerva took a closer look at the alicorn mare and gave a gasp "Michi, is that you?"
Michi smiles, "Forgive me, it's about time someone put the pieces together. May we take this inside?"
"Of course your highness" The red headed stallion said.
"Michi, please I get enough of being called highness at home." Michi requested as she followed them inside, the humans were surprised that the alicorn sat at the table.
The other mare in the home came in to the room with a tea tray in her hands. "Would any one like some tea now while we wait for the food to be done."
"I would love some, please." Michi replied politely
The older mare nearly dropped the tray and stared at the pair of ponies as well.
Michi's horn glowed softly as she levitated the tray to the table.
"Molly, I would like you to meet the new ambassador to the magical world from Equestria."
Molly gave a bow, "I'm honored to have you in our home i hope you and your brother will enjoy your stay here."
Michi looked up through her lashes, "I was frighten that they would put me in a stable, seeing as I'm of equine breed." Before glancing over at her brother, "We do have a problem as well."
Harry look at her and nodded his head "I think i got part of it figure out but i need you to watch in case it goes bad."
Harry closed his eyes, followed the magic he saw as he went through the portal Michi felt the magic build up in his horn, and begin to flow across his body.
Michi quickly spotted a cloak, hanging on a hook, she used her magic to levitate it toward her brother, and fold it around him.
As the magic left, his body he felt his body shift to a new form as he opened his eye he was nearly at the same level as Michi's head. "Wow I'm almost as tall as Michi, Yay."
"Not quite, I am sitting on a chair." Michi replied, as she looked over at her brother, and felt tears prick at her eyes.
He saw the tears forming "Michi, what's wrong? Did i do something wrong? Please don't cry please."
"It's not you, you just resemble daddy." Michi answered softly, just seeing her brother as a human awoke memories long buried.
He reached out to hug her and fell on his face "ow, ow, this is gonna take some getting used to."
"Well you did, live ten years on hooves." Michi teased lightly, "Anyone have some clothing; he can borrow until we can get him a wardrobe?
He stood up once more, wrapped his arms around Michi, and rubs his cheek along her cheek.
Molly jumped up. "Of course, I think Ron's thing might fit him. I'll be right back." and quickly left the room.
Michi looked at the others, "So while we're waiting on clothing, I'm willing to bet a bit or two that you have some questions?"
The other three in the room all stared at Harry then Michi and they nodded.
"Well the first one is how did that happen." Minerva questioned
"Harry is half-human, surely you must remember my mother was not human, only looked like one." Michi answered, "So that is natural for him, or at least with enough practice he will not need magic to change back and forth."
"So if we may ask what have you been up to since that horrid night?" Minerva questioned again
"Just trying to get by day by day, then Nightmare Moon returned." Michi answered
"Who is this Nightmare Moon and why is she important? I'm sorry but there is not much information on your world and a lot was destroyed by the war." Arthur asked as he wrote what she said.
"Nightmare Moon is just name that Princess Luna deemed herself a thousand years ago." Michi answered, "In Equestria, Celestia raises the sun with her unicorn powers, while Luna brings about the moon to bring the night."
"Fascinating this is incredible." Arthur wrote faster.
Michi then told the story about Nightmare Moon.
Harry gave a yelped in the other part of the house "Please ma'am i can dress myself."
"Not as a human, you can't." Michi called out, "Just deal with it!"
"You're not the one standing here without fur and in front of a mare." Harry shot back.
Michi rolled her eyes skyward, "Celestia help me."
"You just calm down, young man. I've raised 6 boys there is nothing to be a shamed of now try this." Molly ordered as she laughed
"Wait until I tell Duster about this, She's going to laugh her flank off at you." Michi threatened
"You are not telling her anything she has enough blackmail on me." Harry gasped
"Then shut your muzzle before I do so for you." Michi replied, "It could be worse, you could changing in front of Cadence."
They heard an eep and saw a flash coming from the room.
"Well now you did it, your highness. He's all yours." Molly walks out of the room with her hair now a platinum blonde; she went up stairs to her room.
"Forgive me, my role as a big sister is demand right now." Michi apologized before getting down from the chair and going to where her brother was located.
Arthur went upstairs to get his wife to come back downstairs.
She walked in to the room and saw harry dressed in a shirt and jeans with an old pair of sneakers. However, his hair was now a blue hue with red highlights.
Michi shook her head, "I should leave your mane like that." she then looked at the female, "May I?"
"Of course." Molly agreed
Michi used her magic to reverse the accidental magical dye job.
Molly gave a relived smile "Thank you your Highness that burst was very unexpected."
"I know, it was both unicorn and human magic," Michi explains, "And its Michi."
"Of course Michi and you must call me Molly as long as you here." Molly smiled and left the room.
Michi gave her brother the once over, "those will do until we can get you something else to wear."
Harry looked at his sister "Please before we head out there Can you fix my mane." he pleaded
"I should leave it like that." Michi replies, before relenting, she fixed his hair.
"Thank you Michi i just couldn't go out there with my mane like that." he hugs her and slowly walks out the room. Michi walked beside him, just in case he lost his balance.
As they both walk back in to the living room of the home there were one more human, one Michi remember as always giving her lemon drops.
Michi placed a wing in front of Harry, signaling him to stay where he was, she put on her public face, and step up to the other humans. "Hello."
The oldest human in the room stood and gave a warm smile and a bow to her. "Your highness, it's good to meet you, I hope you are well."
Michi took a deep breath and released it, if she was highnessed one more time; she was going to lose her temper. She took a sniff, before grinning. "You still smell like lemon drops."
The human laughed and sat right back down "Ahh, Michi, I am so glad you are here; when you and your brother disappeared that night, we were so worried about you both." He gave a smile but she saw tears forming in his eyes.
"I believe that you wouldn't be able to track unicorn magic, at least I think I used unicorn magic that night." Michi explains, looking thoughtful before shrugging, "But it matters not at the moment."
He wiped his eyes. "You're right now for now we must get you both ready for your school and your job, so where is young Harry?"
"My sister has been studying non-stop since she could read." Harry commented, as he was standing right behind his sister.
Albus gave a chuckle "So much like your mother, my dear. Arthur here will help you both get used to this world as well."
"Before I have to dance in diplomatic circles, you mean." Michi came straight to the point.
"Sadly yes but that only till the start of the school year. The next week is just to get you both up to speed and any supplies you may need." Albus replies.
"I suppose that my parents left something in our names, I doubt we can pay with bits." Michi surmised
"Yes Arthur and molly will be taking both you and their children to the bank and the alley to buy the supplies." Albus replied
"Don't worry; I learned a spell that allows me to hide in plain sight of those who are not magical." Michi explains.
Albus just nodded and gave a satisfied smile. Just then, a ruckus was heard outside as four voices yelled "mum, can we have a snack."
Michi moved aside and sat in a corner, ready to have questions to be asked of her, or just plain wanting to pet the pony.
Within a minute four young humans ran in, skidded to a stop, and looked to the professors and the headmaster and Michi. "Umm mum, why is there a horse in the house?" One of the twins asked.
Michi fought the urge to laugh, but her eyes held that laughter, she glanced at her brother, with her eyes, silently saying watch this.
He groaned and shook his head but at the same time, he smiled at her.
Michi calmly stood up and walked up to the one twin who spoke. She opened her mouth, "Hello, I am Princess Dimension but everypony calls me Michi."
The four of them just froze where they were and then the twins just smiled "Great one dad that a real good prank." The third male just stared with his jaw hanging open.
"Not of my doing." Arthur replies,
"And for another thing, I'm not a horse." Michi snorted.
The two young ones fainted and hit the ground.
Harry turned and faced his sister. "You get mad at me for pranking ponies at home but not even here a day and you're pranking my new schoolmates."
"Nowhere in Celestia's rules about being an ambassador does it say be diplomatic to foals." Michi countered, "Besides he deserved it for thinking of me as a horse. Since when do they have a horn and wings?"
"That's not the point you're supposed to be the grown mare here not act like Duster." Harry shot back.
Michi sighed and went over to the fainted humans; she used a wing to tickle them awake.
The boy just waved his hand. "Mum just five more minutes."
Michi rolled her eyes, no matter the species males were alike when sleeping. "I am most certainly not your mother."
They both snapped awake and looked around. "So It wasn't a dream you're really are talking." then he snapped his finger and quickly bowed. "I'm sorry your lady ambassador."
"Call me that one more time, and I will put hoof marks on your hindquarters." Michi threatened
The twins just snickered and quickly left the room. The girl just smiled and spoke in a soft voice "Hello I'm Ginny and your name is."
"Dimension, but everypony calls me Michi." Michi answers, "And I guess you can tell who he is already?"
She saw Harry for the first time and gave a squeak and quickly hid behind her father.
Michi smiles but then shrugged, Harry saw this and blushed as well then shook his head.
"Well, I think I want to go outside, and stretch my wings." Michi declared as she walked to the door, "Unless you need me for something else?"
"No, not at all, we'll call you when it's time to eat." Molly replied
Michi smiled and left the house.
