Doctor Who Fanfiction

The Lost City of Atlantis

While roaming through time and space, Esther was sitting comfortably by the steps of the main control room of the T.A.R.D.I.S reading a book, while the Doctor worked on the buttons and levers, leading the duo to their next adventure. Their last one nearly got the two of them killed by a robotic lion in the Ancient Roman Empire, ruled by a malicious emperor with a hunger for power and creating a "new age" of gladiators.
"The next time we chose a planet or time period to explore, please don't let there be killer robots, Doctor" said Esther, her eyes glued to her book, "I've had enough of those since West Sussex"
"Can't keep that promise, I'm afraid" said The Doctor, "But I am taking you somewhere beyond belief"
"You say that last time"
"Oh but this time, I mean it"
The Doctor placed the switches on, sending the T.A.R.D.I.S flying through space and time, the control room shaking violently as Esther dropped her book and held onto the handle bars to prevent herself from falling. A few minutes later, the T.A.R.D.I.S comes to a stop and moves softly as if it was floating on the surface of water. "We're here!" said the Doctor, walking toward the screen hovering over the control panel, "Oh ain't she a beauty?"
Esther stood up and walked over to the Doctor, looking over his shoulder to read the coordinates, "What exactly are we looking at, Doctor?" she asks, a bit concerned. The time lord smiled and grabs onto the girl's hand, dragging her to the door, opening it to reveal their location "Welcome to the Lost City of Atlantis!" he shouts with excitement, "Well, technically not lost, just invisible to humans since they're not much of a fan of outsiders''
Esther tilted her head in confusion, all she could see was nothing but the water's surface and what appeared to be a giant bubble hovering over it. "Are you sure the T.A.R.D.I.S landed in the right spot?" she asked, "Cause, I don't see anything"
The Doctor turned his head towards Esther, standing beside her with confusion written on his face, "Of course the T.A.R.D.I.S took us to the right stop, I'm sure of it" he said, pulling out his sonic screwdriver to point at the direction of the city. It was then he realized he forgot one important thing, "Oh that's right, how could I forget?"
The Doctor then repositions Esther to a different spot, gently grabs her chin with his index and thumb, slowly turning it to the right and there it was. The "Lost City" of Atlantis appeared right before Esther's eyes in the very distance. The buildings were tall and beautifully displayed, the palace stood in the very center of it with smaller buildings surrounding it and possibly flying cars along with narwhals as a means of transportation. "This is amazing!" she said with a smile, walking towards the city until the Doctor stopped her, grabbing the girl by her waist so she wouldn't fall off the edge.
"Watch where you're going, for heaven's sake" said the Doctor, gently pulling her way from the edge.
"How are we gonna get to the city then?" asked Esther, "There's no way we can swim across, maybe there's a boat or ship to get us there"
"No boats or ships" the Doctor explained, rummaging through his coat pockets until he pulled out a ball of what appeared to be sea kelp.
"Eat this" he said, handing the girl the dripping plant.
Esther looked at the kelp in disgust, holding it between her index and thumb, "What is this?" she asked, trying her best not to vomit at the horrid smell.
"This is a special kelp that allows you to breath underwater" the Doctor explained, "Think of it as if you're eating sushi, without the fish, or the rice, or the soy sauce"
"What about you?"
"Don't need it. I'm a timelord so this is nothing for me"
The Doctor stuffed his hands into his pockets before leaping off the edge with a call, "ALLONS-Y!!!" followed by a splash.
Esther watched as the timelord made a jump for the water down below before her eyes turned back to the kelp in her hand. She hesitates before shoving it into her mouth, forcing herself to chew on it a bit before swallowing it down without vomiting. The taste of salt hit her taste buds hard, even when it swam down her throat, nearly choking. Once the girl is calm, Esther walks towards the edge and steps off yelling "Look out below!" until her feet hit the water.

This water was not like the ocean, that was for sure. The moment Esther entered the water, it felt as if she was being dragged to the bottom of the sea with an anchor tied to her ankle for good measure. Bubbles surrounded her body and blocked her vision on the way down, she could hear the Doctor just a few feet below saying "What took you so long?" through the bubbles. While the time lord landed gracefully on his feet, Esther landed harshly on her bum, feeling the sand cloud up around her. The moment the girl starts to float, she panicked while the Doctor remained unfazed, "Just relax, love" he said, holding the girl's hand for support, "Once you plant your feet to the sand, you should be fine"
As instructed, Esther takes a deep breath, her body starts to relax and weighs her down to the ground, her feet making a soft stomp onto the sand beneath her. "There you go" said the Doctor, adjusting his jacket, "Come along then, we mustn't keep her majesty waiting"
"Her majesty?" asked Esther through the bubbles, "Atlantis has a Queen?"
"Of course Atlantis has a Queen, otherwise Atlantis wouldn't be in hiding"
With that, the Doctor began to stroll down the bottom of the "sea" while Esther took baby steps to not float again and get used to the sand beneath her feet.
