AN at the end.

*inserts usual disclaimer that Frozen does not belong to me*

"I'm afraid that she won't be able to live any longer than a month sir." A series of papers shuffled as a chair screeched out from someone's legs. The room was well illuminated with clean energy but the atmosphere couldn't get any darker.

A tired sob resonates through the air. "Where is she right now?"

"In Ward 13. She is being watched twenty-four seven by a team of professional medics. Her blood sugar, brain rate, and immune system are all operative, it's just… her condition. Sir."

Pairs of strong, callused hands from years of work massage brows that have creased from concentration throughout the inventor's lifetime. Agdar did not expect Anna's health to dissipate so quickly, a year was what he had supposed but through continuous check-ups, it seemed that he had been deemed wrong by science itself. She was only ten years old, far too early in any girl's age to be facing this kind of distress and pain. When she was born, Agdar and Idunn both knew that Anna was not a normal baby but they never could have guessed that she would have heart complications. Since then, time has been an enemy to them and today has proved that they have lost. But Agdar would not give up.

He stood up sturdily from his seat and faced the head physician. "I think now is the time to aim towards my objective." After a quick nod, Agdar started towards the door without waiting for the physician's answer.

Foreseeing that behavior, the medical doctor made for the inventor, "But Sir! You know it hasn't been tested yet! Who knows what will happen to her, and nonetheless you! It's too dangerous!"

Agdar paused in his step so briskly that the doctor almost crashed into him. Strong shoulders raised and lowered with a heavy sigh. He slightly turned back and his eyes shown not with the usual solid, headstrong gleam but of desperation.

"Ludwig, she only has a month. Her birthday is in a month and she's spent most of her life on a hospital bed, connected to various machines and scanned multiple times. The least I can do for her is try, lest she dies knowing that her father didn't even do anything to ensure her life. The statistics from the electrocardiogram show reasonable information and it hasn't faltered since the first day it operated. I think it's ready, and right now there's no direction to go about than forwards."

He continued walking down the hall with Ludwig following silently behind, hesitant to show concern towards the man of the household. Agdar's steps gave the impression that they already knew where they were going; they were only walking down the same hallway towards the lab for three years after all. After a few minutes of turning around corners and going down multiple stairs they were standing in front of a normal door, almost identical to the ones around the manor, except this one had a certain security feature. Voice recognition and breath sample were taken before a series of locks and lasers withdrew from the system. Agdar stepped in before a robotic voice was heard.

"Good evening Dr. Christian. I was informed-", before the voice could finish, a massive phaser shot out from behind Agdar and was pointed at the doctor. The poor man doubled back out of surprise and landed on his butt, eyes wide with horror and the gun following his every move.

"Unidentified guest does not appear on the list Sir. Shall I commence obliteration?" The humming grew louder as an orange light enhanced from the weapon. Agdar waved it off, "No need to EVE, he's a friend. And cancel the automated vacuum division, I swear, you go to great lengths with this whole security thing." The inventor turned on various switches and nobs before turning back to Ludwig.

"It's alright doctor, I've told EVE to hold off the hostilities. I want you to see this." He flicked one last switch and a sequences of lights turned on, directed toward Agdar's creation. Ludwig stood up reluctantly and walked cautiously into the lab, mouth agape and not even noticing beams of light flashing upon him, scanning. "Dr. Ludwig Von Drake, born 2002, March 13, age 52. Blood type AB, with a BMI of 21. Criminal record empty. Graduate of King Philip Magnet School and obtained a doctorate in medical science at the Medical University of Corona. Suffers from frequent migraines and Chronic Obstructive Pulmonary Disease-" EVE continued sputtering information as the doctor joined his friend.

"You smoke?" Agdar shifted his eyes to his side to his friend. Ludwig shrugged his shoulders. "It relieves the stress from operations." He then gestured towardswhat Agdar had highlighted. "Is this it now? How..."

"It has been under the normal pressure a human has and the regulation of fluid is at the same rate. It has been going strong since then, with and without supervision."

There in front of them, in a glass cylinder was a clear device strikingly similar to the human heart, only this had metal rings where the arteries and veins would be fastened to and comparable tricuspid and bicuspid valves. Fairly parallel to the actual thing only there were translucent wires around the left and right arteries, superior vena cava, and left and right veins. On the apex of the heart was a tiny rectangular box that conformed to the shape of the bottom of the artificial heart. It was pumping fluid into the atriums and an action potential can be seen flying through the crystalline wires and over the ventricles, pumping the fluid out the appropriate exit.

The doctor ran a shaking hand through his white hair and let out a breath, "This is- this is phenomenal Agdar! You have made the impossible! Scientifically impossible! Normal blood pressure, blood rate is good, even the diastole and systole are not hesitating! And that black box is-"

"Is the main power for the heart, yes. Completely safe, I tested it multiple times in different situations, and all clean power, probably the cleanest in Corona." Despite the depressing news that were weighing down his shoulders, the inventor couldn't help but puff out his chest in pride. He had worked on this for Anna and his exertion finally paid off. Now it was time to give it its purpose.

"Apologies for the interruption Sir, but I send you my condolences and concern on the behalf of your daughter."

"Thank you EVE, and I appreciate the care, but that won't be necessary, Anna will be alright and operation will commence tomorrow morning." He faced Ludwig and pulled a weak smile.

"She will be alright."

Prologue! Thanks for checking this story out! This is my first elsanna fic so I hope I contributed to the fandom with this littl idea of mine. I took anatomy class in high school and am currently in a kinesiology class so I know a few things about the body (sorry if there are any errors, I wrote this in the summer, the time I'm supposed to be relaxing from school), so yeeaaaa this was just going to be a story that I wrote for myself but I thought eh, why not? Rating will be M due to violence and language and maybe some plotless(?) sut later on? Till next chapter mates!

Edit: I am so frickin sorry. I uploaded the still-in-progress version of this story. Fixed it
