A/N; Shawnie-cat; Funny Shawnie, you added to my prank at the end, since I only did the Potter twins.

Shawnie; I thought there should be others along for the ride, and thanks for keeping the original name, even if it is now her nickname.

Shawnie-cat: No problem there, I always like the original name, but I didn't want to use it for this story.

Shawnie; Alrighty then, lets get on with the story.

We don't own Harry Potter nor Figure 17, and please review.

In a twenty foot diameter golden room, while two teens slept on two king's size bed, a child's voice was heard about." Let the Courage of Heart, Piece of Mind, Strength of Body tests begin!" The child called out." Also may my power encourage thy will, and never stray from the light!" The child continued, and the teens glowed brightly white, as did the room.

For a few minutes, the light dimmed, and the room returned to normal." It's done and they have passed my tests!" The child happily said, and then giggled." A little prank wouldn't hurt my new master would it?" The child thought, and all was quiet in the room.

For an unknown amount of time the teens slept, until one blink, and the other blink." Harry is we dead?" The young girl weakly asked, as she rubbed sleep from her eyes.
"After what happen at the graveyard, I hope we are, since I don't want to go threw that again!" Harry groan, remembering all the slashes he got, and the pain from them.
"Don't remind me, but unfortunately I don't think we are dead." Jamie informed her disappoint twin." Since I don't think dead people go to a plain round room, all weak and such." Jamie informed her twin, as she tiredly got up, but quickly lay back down from exhaustion.
"I guess we should sleep until we are fully rested, before seeing if there is a way out of here." Harry yawned, as he closed his eyes and went to sleep a second later.

The next time the twins awoke, they only could sit up, and was surprised to see a large tray of food and drinks on a small table besides their beds, and both quickly dug in since they were very hungry.

Both twins slept and woke three more times before enough of their strength returned for a little walk about the small room." Now what Harry, I think we are trap since we can't seem to teleport out of here?" Jamie worriedly asked her twin, as she turned to face him "I wish I knew that, this room is just a bare room, with nothing to tell us where we are?" Harry sighed, as he again looked about, hoping to find something he and Jamie miss, but there was nothing but the two twin beds in the room.
"I wish we had some answers to where we are!" Jamie shouted, and to her and Harry's surprise, a voice sounded.
"You only need to ask, by the way!" A child voice sounded from around the room.
"WHAT WHO ARE YOU, AND WHY ARE WE TRAP HERE!" Both twins shouted since both were not too happy being trap here.
"Please you don't have to shout." The girl firmly asked, and then continued." I saved you both and Kaitlyn from the ocean, and I was the one who healed you both, and now that you are well I can give you the fourth Figure, since I know I can trust you with it." The girl explained, startling both twins. "Wait you know where the fourth Figure is?" Jamie quickly asked.
"I do, and I can take you both now, since you need its powers to help rid the world of Dark Magic." The child informed the twins.
"Then please take us to where the Figure is, and we'll do our best to stop Voldemort!" Harry firmly committed and in an instinct the room dissolved and the twins was in another round room, with a star shape crystal floating in the center.

As the twins looked to the crystal, Jamie quickly spoke up." Um before we do anything, do you mind telling us who you are, and where exactly where we are?" Jamie quickly asked, and to her surprise got a reply.
"My name is Atlantia Guardian of Atlantis, and Keeper of the most powerful Figure to come to our world, and that will include you Jamie." The Child informed two shock teens." And as to where you are, you both are under miles of ocean, and please when you leave here, don't come back, since this room and all of Atlantis will be gone the second you leave here." The child regretted informed the twins.
"Wait what you mean Atlantis will be gone?" Harry quickly asked.
"The ward that is keeping Atlantis intact is powered by the Figure, and once it's removed, the wards will collapse taking the city with it." Atlantia sadly informed the twins.
"What about you, what will happen to you?" Jamie worriedly asked.
"As to that question, I don't know, since I'm tied to both the wards that still protecting the city, and the Figure, maybe I will just cease to exist." The child informed the twins.
"We can't do this, we could learn allot from the Atlantian race, since I heard there was many things lost when the city disappeared." Harry quickly informed the child.
"I'm sorry to say, that the wards only saved the city, not what was in it, so you will only find empty stone buildings, and nothing of what was in them." Atlantia regrettably informed the twins." So please accept the Figure, since it will be a great help to you both." Atlantia asked, and the twins sadly accepted it.
"Please can we see the Atlantis before we leave here?" Jamie quickly asked.
"Walked up to the walls of the room, and I will show you the once great city of Atlantis." Atlantia proudly informed the twins, which the two went to face the walls, and instantly the walls became transparent, showing them in a very tall tower, on a huge star shape build, surrounded by a wall that connected the pointed star.
"WOW, Atlantis is huge!" Harry only could say, and Jamie only could nod in agreement.
"Now that you seen Atlantis, I believe it's time for you both to leave, since everyone you care about, think you had died." Atlantia warned, and the twins looked worried.
"What do we need to do?" Both twin quickly asked.
"Go to the crystal and stand beside it, I'll do the rest." Atlantia gently informed the twins, and both went to stand face to face, with the six inch crystal between them." Now prepare yourselves, and please use this Figure well." Atlantia sadly informed the twins, then in a flash of light, the crystal was gone, and in its place was an unclothed baby girl.

It took a moment for the twins to speak, since they were in shock at seeing the baby girl floating before them." This can't be right this child can be passed as our daughter." Jamie worriedly informed her twin, since the baby had messy red hair, and green eyes just like both twins.
"I don't think this can't be help, come on we should at least put clothes on her, and then we better be on our way." Harry quickly suggested, and both twins quickly dress the little girl, and then looked about.
"Um Atlantia, I guess we will be going now!" Jamie informed the Guardian, but got no reply, so both twins teleported away.

Seconds after the Potter twins was gone from Atlantis, the once great city vanished from the ocean floor, only to be replace by untouched coral reef.

Hogwarts

In the Headmaster's office, Dumbledore sighed as he looked threw his paperwork." I think I'm started to feel my age catching up with me." Dumbledore sighed again, since it's been two weeks since the Potter's so called death, and nothing more was learned about Atlantia, and the Hat was not saying anything more." I guess I better get this paperwork over with." Dumbledore thought, but froze as he looked up." Come in Mr. and Ms. Potter." Dumbledore only could say, since they was the last ones he would think would be here now.

The second Dumbledore called them in, Harry and Jamie stepped into the Headmaster's office, looking very worried." Um sir, I think we have a problem?" Harry quickly informed the Headmaster, and once the age professor saw the little baby in Jamie arms, he fell of his chair in shock.
"Ah I, I think I will call your Guardians before you start explaining about this child." Dumbledore only could stutter out, as he shakily got up, and went to his Fireplace and fire call the twin's families.

With a sleeping baby girl in a conjured cradle, the Potter twins nervously waited for their Guardians, and within five minutes, Dumbledore invited in his guests.
As soon as five adults entered his office, Dumbledore smiled." I called you here today, since I have some wonderful announcement concerning certain twins." Dumbledore smiled, as he pointed to the side where two teens nervously stood.
"HARRY, JAMIE…" The guests quickly shouted in shock.
"Yes that will be us…" Both teens started, but stopped by a number of hugs.

Five minutes later after the twin's reunion with the Weasleys adults and the Blacks, they were interrupted by a smiling Dumbledore." Excuse me before we go further into your celebrations, I think the twins need to change someone's diaper." Dumbledore amusedly informed everyone, while wrinkling his nose at the smell coming from the crib for the little girl.
"Oh no…" Both twins called out, then went to change the little girl, and magically freshen the room from the bad smell.

Once the little girl was change and happy playing with the teens, Sirius and Cara whom was shock at what they saw quickly spoke up." HARRY JAMES POTTER, this better not be what I think it is!" Cara and Sirius yelled, causing the twins to shiver.
"This isn't what it look like, and plus would have anyone notice Jamie during the last year." Harry quickly informed everyone.
"True, unless she was using concealing charms, so she won't show." Dumbledore amusedly suggested, as the twins turned on him.
"YOU ARE NOT HELPING!" Both twins shouted, and a second later, there was laughter coming from about the room, causing everyone to look for the source of the noise.

It took a second for Dumbledore to find out who was laughing, and turned to the shelves where the old Sorting Hat was laughing his head off." Hat, what is so funny?" Dumbledore firmly asked, as the Hat stopped laughing to answer.
"It appears that the famous Heirs of the Marauders have finally met their match." The Hat chuckled, causing the twins to look to him.
"What do you mean HAT?" Both twins quickly asked, but the Hat turned to the crib.
"My dear Atlantia, I think it is time to show yourself before you get your new master in serious trouble." The Hat amusedly suggested, a second later a light blinked from the crib, and another flashed before the startled group, to reveal a three-year-old girl, with brown hair, silver eyes, and a look of intelligence far beyond her natural years.
"Hi my name is Atlantia, former Guardian of Atlantis, and a Figure 16 unit." Atlantia smiled as she looked to the shock looks of everyone.
"Don't forget master prankster of that era, and still hold that title, since I don't think anyone can match your skills." The Hat smiled, as the young girl turned on him.
"You had to reveal that now, thanks allot I was hoping they wouldn't guess I would be the one who will be pranking the school this coming year." Atlantia pouted, but quickly covered her mouth, since she just confessed her plans.
"Master prankster hah, exactly how long you had been pranking my dear?" Cara worriedly asked.
"For several hundred years, after my former master pass away, and I became Guardian of Atlantis." Atlantia informed everyone with a shrugged." I had nothing better to do, when I was not protecting the city, and everyone did enjoy my pranks." Atlantia innocently informed everyone.
"Is that so, can you explain why Atlantis sunk, while you were a Guardian, and from what I read a very powerful one." Dumbledore firmly asked, causing everyone to look at the little girl.
"It was not my fault, the Wizarding government tried to release my sealed magic, in hopes I could protect the city better, which I had no idea why." Atlantia sighed, as she continued." They did a terrible job at it, and caused a massive magical power surge throughout the city, destabilizing all the wards, and that what cause the city to sink, since many of the wards kept the mobile city afloat on the ocean." Atlantia sadly looked down, looking sorry about the lost of both lives and the great city.

After seeing how Atlantia was looking, Cara quickly picked up the surprisingly light child, and gave her a hug." We won't blame you for something you had no control over." Cara sadly informed the little girl, and the other adults quickly assure the girl.

With the little girl assured, Dumbledore smiled." Now little one, what shell we do with you?" Dumbledore gently asked, as Atlantia looked to him with her silver eyes.
"I need to stay with my new master, and help look after him like Jamie." Atlantia informed a shock group.
"No you much too young to help us!" Molly firmly informed the little girl.
"No I am not, I may look little, I'm at least ten-thousand years old, and more then enough to help out." Atlantia firmly informed the adults.
"And how can one so young looking can help us?" Dumbledore uncertainly asked.
"Because this is one of many forms I have, I mainly use this one to blend in with Humans." Atlantia informed a startle group.
"Ah how many forms do you have?" Harry nervously asked the little girl.
"I can turn into any light magical or non-magical creature on this planet, so I can help allot." Atlantia firmly informed her master.
"In that case, I think we should welcome a new inhabitant of Hogwarts, and Potter Place." Dumbledore proudly informed everyone as he took the little girl her in his arms." But you need to promise that you will be good to your new master alright?" Dumbledore smiled, even if he saw some mischief in the little girl's eyes.
"I will be good little girl." Atlantia firmly informed Dumbledore, but not adding a promise to it.
"Then in that case my dear, you should be welcome for now as Kaitlyn's younger cousin, so you will be accepted by the student body, and give a reason for you being here alright?" Dumbledore gently asked, and Atlantia nodded in agreement, before Dumbledore turned to the others." This will her cover story, her family was recently killed, and since Kaitlyn is her only living relative, she will be staying with her or the Potter twins, since they are like brothers and sisters." Dumbledore suggested, and everyone agreed with the plan." Now that said, we are a bit late for dinner, so let's reintroduce three lost students, and a new addition to Hogwarts." Dumbledore suggested, and carried Atlantia out of the office with the others following.

In the Great Hall, dinner was half way done, when the doors opened for a smiling Dumbledore carrying a shy looking girl in his arms, and with him several adults, walked to the Head Table, and Dumbledore stood before everyone." Now I know many of you are wondering who this charming young witch in my arms is and I will tell you." Dumbledore proudly informed the entire hall." This is Atlantia Evans, she is not only a cousin to Kaitlyn Evans, and Atlantia was officially adopted by Kaitlyn, since she is her only living relative." Dumbledore proudly informed everyone, as the door opened for a dark red hair teen, whom smiled at her friends as she pass them.
"Don't worry, we all are back!" Kaitlyn whispered to her best friends, and they smiled as Kaitlyn took her spot beside Dumbledore.
"Welcome back Kaitlyn, and I hope this will be the only surprises you have to offer." Dumbledore smiled proudly, as did Kaitlyn.
"No not now, but maybe later." Kaitlyn smiled, as Dumbledore continued.
"Now I got more good news, it seemed that we had over estimated a couple deaths recently, and I need to correct it now." Dumbledore started, as everyone look to him." It seems that the Potter twins are alive, and back to continue their schooling." As Dumbledore informed everyone, the doors again open for two once thought dead students, and everyone gasps at their entering.
"HARRY, JAMIE…" The Potter's friends quickly yelled, and quickly got up to hug their lost friends.
"Hey guys we are back, and this time for good." The twins assured their friends as they sat down to begin eating at their table.

Talk was pleasant as the Potter twins spoke with their friends, until a flash of light appeared startling everyone, and then words appeared in the air.

THE HEIRS OF THE MARAUDERS REIGN HAS ENDED

AND THE TRICKSTER REIGN BEGINS

SO YOU BEEN WARNED

SIGN BY

KITSUNE THE ONE AND ORIGINAL PARTY ANIMAL

Once the Potter twins read the note, they looked to Atlantia, whom was smiling at them." I think we are in trouble." Jamie telepathically informed her twin.
"What gave you that idea, there is no way we can compete against a ten-thousand year old prankster." Harry groaned, getting another set of twin's attention.
"Harry, Jamie, do you know anything about this?" Fred quietly asked.
"Cause we could use some help with our Prank War with you both." George added.
"Yes we know who Kitsune is, but…HEE HAW, HEE HAW!" Harry tried to continue, but made donkey noises to his embarrassment.
"Harry is you…MEOW, MEOW!" Jamie tried to speak, but made cat sounds.
"Wow he got you…RUFF, RUFF!" George started barking like a dog, when he tried to speak.
"Oh goody now my…TWEAK, TWEAK!" Fred quickly chirped like a bird, and soon other sounds joined in.

At the Head Table, Dumbledore was watching in amusement at the spectacles before him, before he looked to Atlantia sitting on his lap." I'm glad you didn't add that promise…ROAR, ROAR!" Dumbledore started roaring as a lion, and his eye still twinkle with amusement." Well things went back to normal pretty quickly." Dumbledore amusedly thought, as the other professors started making animal sounds.
