13 year old Emma was not born a normal mermaid she unlike her parents had magic but she had to practice in secret so she'd turn herself into human and practice on land, one day king David and queen Snow White Emma's parents found out what she had been doing and forbid her from leaving the palace for 8 tidal moons (8 weeks) but Emma was not going to be told what to do she had magic after all so she swam out her bedroom window and headed to land.

Emma was almost to the surface when a huge storm hit forcing her to go down deep problem was the water was churning so badly that she didn't see the rocks and she cut her tail and banged her head knocking her unconscious.

When Emma woke the sun was shining brightly but it was also very hot which was causing her tail to dry out suddenly there was a shadow over her and she looked up into the brown eyes of a beautiful brunette who was possibly a bit older than herself.

Emma was about to say something when the brunette covered the cut on her tail with both hands which started to glow when she removed her hands the cut was gone.

"How did you do that? I didn't know that humans had magic."

"Most don't I'm one of the few that do."

"Do your parents know?"

"Yes they do."

"How'd they react when they found out?"

"They already knew I would have magic because my mother has it too."

"My parents didn't know till they found out that I was able to turn myself into a human to practice, no other mer person in my kingdom has magic I'm the only one."

"What happened?"

"They forbid me to leave the palace for 8 tidal moons."

The brunette had a confused look on her face.

"You call it weeks. So I swam out my bedroom window. Then there was a storm and I must have cut myself on something there was also a sharp pain in my head before everything went black then I woke up here and now met you."

"Well you'd better change into human and come with me because I can't very well explain why I'm dragging a mermaid."

Emma concentrated and she felt her tail melt away to form legs, a blush bloomed across the young mermaids face when she realised she had forgotten to visualise clothes.

"Now I know why Ariel wore seashells."

"I can help you out here."

With a wave of her hand the brunette had clothed Emma in a beautiful gown it was a blue as her tail was.

"Thank you so much."

"No problem. I'm princess Regina Mills."

"Princess Emma Swan, you know I can give you anything you want."

"What?"

"When a human saves a mermaids life they are granted what they want the most."

"Are there any restrictions?"

"No we're not genies it's really the only magic we all have."

"So when you said that the others didn't have magic you meant..."

"They don't have powers like I do."

After that Regina took Emma to her castle where the brunettes parents welcomed the mer princess with open arms as if she were a part of the family.

Days had passed and the two girls were getting closer and Cora and Henry could tell they were falling in love with each other so they decided to playfully embarrass the girls.

"Emma? Regina? Could you girls come here?"

The girls raced each other trying to be the first one there.

"Mother what is it?"

"Your father and I have noticed how close you two have become and we thought it was time that we had a little talk."

Both princesses were sacred that Cora and Henry had decided to send Emma back to the ocean where the palace guards were sure to be waiting to drag the mer princess home.

Seeing the look of fear on the girls faces Cora continued.

"Don't worry dears we're not sending Emma back to the ocean we wanted to talk about magical reproducing and practicing magical safe sex."

"Mom!" Regina said horrified while Emma's mouth just hung open like a clubbed catfish.

Suddenly Cora and Henry started to laugh at the look on both the girls faces.

"Did we embarrass you girls?"

Before either girl could answer Emma collapsed.

"Henry send for the blue fairy."

Soon the blue fairy came flying in.

"You summoned me your majesties?"

"Can you help Emma?" Regina asked.

Blue flew over to the unconscious princess and used fairy dust to determine what was wrong with her.

"She is fine she just needs water."

Regina used her magic to send Emma into the pond in the courtyard.

"What was wrong with her that she needed water for?"

"She is a mermaid correct?"

"Yes."

"Well even mermaids in human form need water guaranteed they don't need it as much as they do in their true form but they still need it."

"Thank you Blue."

"Here is a book on mermaids so you'll know all about them."

"Before you go did you know she's the only one in her kingdom with powers apart from the one they all have?"

"She does but that's not possible. Unless..."

"Unless what?"

"It is true that there is only one mer kingdom that has magical mermaids they are ruled by King Triton but all his daughters are accounted for which kingdom is she from."

"It's ruled by queen Snow White and king David."

"Ah then she is indeed special for when Snow White was pregnant with the princess, a magical mermaid came she was dying from a rare disease that only mer people from a kingdom that died out eons ago could contract, and she only had a day to fulfil a prophecy where the unborn princess would be kissed by the moonlight and possess magic as pure as the moonlight itself. Once the princess was born the old mermaid took the princess up to the surface so the moonlight could touch her when it did the mer princesses tail change color from just Caribbean blue to Caribbean blue with silver and gold lines diagonally wrapping around, she had a blue crescent moon on her right temple, and her hair had changed from black like Snow White's to blonde like she has now."

"There's so much more to her than I realised."

"There certainly is princess Regina."

"Dear why don't you go check on her."

Regina left to talk to Emma about what she was told, when they both came back in the blue fairy had gone.

"How are feeling dear?"

"Much better thank your majesty."

Suddenly there was a knock at the door Henry went and opened it there was sea lion looking at him.

"Yes can I help you?"

"My name is Selkie it means sea lion in mermaid talk I am here to warn princess Emma."

"Come in."

"Thank you."

When Henry and Selkie made it to where Emma, Regina and Cora were waiting Emma saw Selkie and ran over dropping to her knees and hugged her friend.

"Selkie I have missed you so much."

"I have missed you too."

"What are you doing here?"

"I came to warn you."

"What about?"

"Your parents are seeking help from Ursula to gain legs and bring you back home where they will lock you away until they are certain that you won't swim away or use your magic again."

"They can't do that it's not fair."

"Regina they can do it unless..."

"Unless what dear?"

"Well the only way for them to be unable to take me away is if another royal family mermaid or human place me under their protection, my parents will have no choice but to let me go."

Suddenly the door to the castle is flung open at first Emma thought her parents were there already but then a woman with horns came in.

"Maleficent how are you my dear?"

"Quiet well Cora, hello Henry and to you too princess Regina my how you've grown."

Then Maleficent spotted Emma who was hiding behind Cora clinging to the queens cloak.

"And who is this beautiful young girl?"

"This is Emma. Come on out dear Maleficent won't hurt you she's a friend of the family."

Emma crept out from behind Cora and stared at Maleficent.

"Hello Beasty."

"How dare you call me a beast!"

Emma was furious and it showed as her finger scales changed color.

"Emma it wasn't an insult she even calls Aurora that it's just a pet name."

Emma's anger simmered down and she was calm once again.

"I am sorry I shouldn't have gotten angry like that."

"It's okay."

"So what made you decide to come see us today?"

"Well I had heard from a little bird that you had taken in a mermaid and I had to see it for myself but I must say I never dreamed that it would be the daughter of Snow White and David."

"You knew who she was born to?"

"Naturally. And you won't be able to protect her with the army you have they're all very green."

"We won't need the soldiers if we place her under our protection her parents can't touch her."

"Cora that won't stop those two they'll just take her anyway."

"What can we do to stop that?"

"Don't worry Regina I will lend you the strength of my army who have won more fights then you've been alive I will also lend my help and my daughters help."

"When did Lily get back?"

"About a week ago but she was wounded some soldiers tried to shoot her down I'm trying to heal her as fast as I can but I don't possess the ability to heal her fully."

"Could I help? I healed Emma's wound on her tail."

"It wouldn't be enough you're still new to magic."

"I can do it."

"You'd do that for me?"

"Well you are willing to help protect me from my parents it's the least I can do."

Maleficent used her magic to bring Lily into the room, Emma went over to her and placed her hands above Lily and Lily's whole body started to glow silvery soon Lily's wounds were gone and her eyes opened.

"Mom?"

"It's ok sweetheart you're going to be ok now."
