Author Note: Harry gets an unexpected gift on his 16th birthday. A family heirloom that changes himself and his closest friends in rather interesting ways. Something I was just horsing around with.

(BEGIN)

Harry was sitting at the Burrow for his sixteenth birthday. He was enjoying the time with his friends in spite of the dark events swirling around them.

"A package arrived for you Harry. From the goblins." Arthur announced as Ron, Hermione, Luna and Ginny were sitting in the living room with him playing cards and listening to the radio.

"Oh. Do I need to do anything?"

"No Remus and I already went over it to make certain it was safe." Arthur said handing a small package over. "I hope you don't mind."
"No. It feels good to have someone looking out for my safety." Harry chuckled.

"Well what is it man?" Ron demanded.

"Ron! Behave." Hermione huffed.

Harry shook his head at his friend's antics but opened the box carefully. On a green cushion was a small silver amulet on a thick woven chain. A small folded piece of parchment was tucked into the back.

Pulling the parchment out he showed the amulet to his friends. "I wonder who sent this?"

"I don't know but its pretty Harry." Ginny said.

Harry nodded and unfolded the parchment. Frowning he handed it to Hermione, "I can't read this."
"That's because its in old English. Just after the Saxon period." Hermione said glancing at it.

"Well what does it say?" Harry asked.

"It says, Greetings child. I am Aerlias Potter Son of Ertors Potter. I am the current Horse Lord and have been told by my prime wife that you will be the next horse lord. Though your time is many, many, years into the future I will see that the goblins hold it for you until you can take up the mantle. Place this around your neck then with a drop of blood say your name and declare yourself the new Potter Horse Lord."

"That's it?" Harry asked picking the amulet out of the case.

"That's all it says." Hermione said passing it to Luna who nodded, "that is what it says Harry."

"Hunh. I never heard of a Potter Horse Lord." Arthur said, "Although many families had their own titles and honorifics. Especially in the older days."

"So it should be safe to take this title?" Harry asked.

"I suppose. Maybe it means you'll be a horse animagus or something." Ron chuckled.

Harry shrugged then before he could prick his finger Arthur cleared his throat, "Perhaps you and your friends could do this outside. Just in case something happens."
Harry chuckled and stood, "True. I don't wanna wreck the place."

"Thanks Harry. I'm sure Molly would appreciate it as well."

Stepping outside Harry and the others formed a small circle while the adults stood back watching.

Hermione pricked Harry's finger with her wand drawing some blood. Putting his blood smeared finger on the amulet around his neck Harry said in a loud voice, "I Harry JAMES POTTER CLAIM THE TITLE OF POTTER HORSE LORD!"

Nothing happened for a second causing Harry to chuckle before a bolt of white hot energy seared through him a split second later he felt his body shifting and changing. Things moving and growing as he fell onto his hands. He heard the others screaming briefly before their voices changed. When the energy stopped he shook his head, realizing he had a long mane he said, "Whoa! I'm a horse!" Looking back over himself he could sort of tell he was a pure black stallion.
"So am I" He heard Hermione's voice come from a beautiful chestnut mare.

"I believe we all are." He heard Luna say. Only she was a brilliant white unicorn.

"Luna you're a unicorn." A sorrel mare said in Ginny's voice.

"Oh that explains a great deal then." Luna said nodding her head.

"Damn that felt weird." An unknown female voice said from a strawberry roan mare.

"Ron? Why does your voice sound weird?" Hermione asked.

"I dunno. I feel odd." Ron shook himself, "There's something really not right."

"Guys. I don't know what happened but can we go back to being human?" Harry asked.

"I'm sure we can. Its just a matter of will and vision. Sort of like what an animagus uses." Hermione said. She was lifting her foreleg to try and look at her hoof.

"Right. I want to go back to being human." Ron said whimpering.

The adults were talking among themselves as Harry nodded, "Yeah me too."

"Well let's try." Hermione said.

Harry concentrated on chanting 'human, I'm a human.' in his mind. A few moments later he felt his body shrinking and shifting until he was a naked human male standing in front of four naked human females. Only each girl had a horse tail sticking out of the base of their spine. He also realized he was not wearing his glasses. "Hey we're back to normal. Sort of."

"Speak for yourself!" Ron exclaimed as he held his hands over his bosom. "I'm A GIRL!"

"Yes and a moment ago you were a horse." Remus said walking up. "I assume you were speaking to each other?"

"What you didn't hear us?" Harry asked as Remus used his wand to reassemble their clothes.

"We heard horses nickering and whinnying." Arthur said walking up.

"Oh boy. Now what?" Harry sighed reaching to take the amulet off, only to discover it was gone. "Great. The amulet is gone."
"Its probably part of you Harry." Hermione said trying to slide her knickers up her legs and frowning. Her thighs were thicker than they had been before. Giving up she pulled her skirt on as her waist was still the same, tucking the waist under her tail. "We've had some physical changes."

"Yeah man. Look down." Ron said with a grin.

Harry looked down and realized that Neville was no longer the best hung guy in the dorm any more. "Oh wow."

"Yeah oh wow." Ron sighed.

"Ron are you getting turned on by Harry?" Ginny laughed.

"Yeah well." Ron looked worried, "Oh crap. What does this mean?"

"If you'll look on your left hip you'll see a symbol of the amulet on each of you." Remus pointed out.

Each of the girls examined each other and Harry. Only the girls had the symbol though. "I wonder what that means." Harry asked.

"If you will recall the letter referred to a prime wife. Apparently the horse lord has a harem." Luna pointed out.

"Oh. Wow." Harry said pulling his trousers on. Being careful to tuck himself down one leg. "And all of you are my harem?"

"Apparently. Which why Ron was transformed and not excluded is rather concerning." Luna observed.

"Look. I. I dunno." Ron had gotten dressed quickly. Huffing when his trousers no longer fit the bottom heavy figure. Although his Chudleigh Cannons shirt fit but was a midriff shirt thanks to the large grapefruits on his chest.

"We can talk about that later. We need to figure out what all changes there are. And why do all of you have tails?" Harry sighed, "I wish I knew more about my family history."
"Maybe Dumbledore would know." Molly suggested.

"I'll go contact him." Arthur said stepping inside.

"Mum. What's going on?" Ron asked.

"I dunno." Molly said giving the new girl a comforting hug.

"Can you see if Ron's really a girl?" Hermione asked.

Molly nodded and drew her wand. Casting several spells at Ron she smiled, "So wht do you want to be called now?"

"What do you mean mum?"

"As far as I can tell dear. You're fully a girl. This transformed you inside and out." Molly said.

"Oh damn. Damn." Ron collapsed to the ground then shifted, "Damn tail!"

"You know if you had been a girl we were going to call you Veronica." Molly said stroking the long red hair.

"Yeah sure. That'll work." Ron, now veronica said.

"Let's get inside and relax until Dumbledore gets here and can help us figure this out." Harry suggested.

"Good Idea." Hermione said stepping beside Harry on his left while Luna took his right side. Ginny and veronica following them inside. Molly watching them go shaking her head.
