A/N: Hello readers! Sorry for the delay but I haven't been able to get to a computer for a long time. I am also going away for the next three weeks so no more chapters until I get back (sorry!). I hope you enjoy this chapter and PLEASE REVIEW!

Yalaea managed to take a lungful of air before she was dragged under water. Immediately she couldn't see anything but was surprised to find that she could still breathe. Yalaea took a deep, calming breath and waited. She waited for what seemed a century until a small light appeared below her. In this light Yalaea looked around and found that Amy and Rory were being pulled downwards not too far from herself. She glanced upward and sighed with relief as she saw the Doctor following them down. Yalaea saw movement below her, flittering above the source of light. She couldn't quite make out their shape but she could see that they had tails that looked a lot like a tail of a swordfish. The creatures were a greyish blue, the colour of the surrounding ocean and their hair floated out behind them like seaweed. Merfolk, Yalaea thought, what are Merfolk doing here? To this she had no answer. Yalaea slowly descended towards the Merfolk and they parted to let her through. She gasped as a beautiful city came into view. Oh My God! She thought. The city was astounding. It shimmered under the water and it glowed with a cool blue light. Yalaea was dragged slowly towards one of the main buildings, presumably the town hall. Yalaea was propelled through the doors closely followed by Rory, Amy and the Doctor. They landed on the floor, still able to breathe and were immediately surrounded by Merfolk, though they only saw females. Each Merfolk carried a trident in one, webbed hand and their eyes were lidless and staring. Their skin was a greyish green colour with fanged teeth protruding from their mouths. They hissed and snarled as Yalaea, Amy, Rory and the Doctor were propelled through the hall. They flew threw a huge pair of wooden doors and they were stopped before a throne-like chair. One of the Merfolk was on the chair, a massive, golden trident in her hand. The Mermaid looked up at the four friends and opened her mouth.


"Who are you?" she rasped, swimming closer to examine them.
"We're just passing through…" the Doctor said,
"You were trespassing!"
"We were swimming!" Rory exclaimed.
"No one is permitted to swim there!" the Mermaid's eyes blazed red, "No one!"
"How were we meant to know that?" Amy asked,
"That is of no importance to us!" the Mermaid hissed "You are not allowed in our sacred waters!"
"Well…" the Doctor began "We are very sorry and we did not want to displease you but…we really have to go…"
"NO!" the Mermaid rasped "You are ours!" she turned to two of the Merfolk present "Take them away!"
The Doctor shot a warning glance at Amy and Rory, warning them to be silent. Amy took Rory's hand and allowed herself to be herded out the doors. They were herded down a long corridor and through another set of doors, though these were made of steel. Inside the doors there were a set of stone steps leading down into the blackness. The Merfolk gave each a shove, sending them tumbling down the steps. Amy landed on top of Rory with a squeal closely followed by the Doctor and Yalaea. "Ow!" Yalaea mumbled, rubbing her back. "Tha' hurt!"
"You think?" Rory mumbled shifting Amy off his lap.
"Where are we?" Amy asked, standing up.
"No idea! Isn't it brilliant?" the Doctor beamed, leaping to his feet.
"Maybe…" Yalaea said warily, remembering Rhith. The Doctor shot her a sympathetic glance,
"Sorry" he said softly.
"It's fine" Yalaea dismissed it with a wave of her hand. The Doctor smiled before scanning the room. It was still underwater and the Doctor didn't know how they were breathing or how long it would last. He examined the walls, solid rock covered in a thin layer of moss and glanced upward. There was no visible ceiling, only blackness.
"We could try swimming up?" he asked,
"We could…" Yalaea's eyes followed the Doctor's. "We could be trapped and we don' know if our 'air supply' or however we're breathin' will last…" she turned to Amy and Rory "Wha' do you think?"
Amy shrugged "We should try. I'll die of boredom if I don't do something soon!" she attempted a smile but Rory saw through it and wrapped a comforting arm around Amy's shoulders,
"We'll be fine, we always are…" he said reassuringly.
"Well…wha' are we waitin' for?" Yalaea asked as she kicked off from the ground and swam upwards.
"What indeed?" the Doctor muttered as he followed Yalaea with Amy and Rory close behind.
They slowly swam upward into complete darkness. "Doctor?" Yalaea whispered,
"Yeah?" a disembodied voice came from somewhere form her left.
"I think we should all hold hands so we don't get separated…?" Yalaea started to move towards the Doctor's voice,
"Yeah. That's a good idea." The Doctor's hand grasped Yalaea's and held it tightly.
"Amy? Rory?" Yalaea called a bit louder.
"Yal?" Amy voice floated towards them.
"Come towards me voice" Yalaea said and waited. She felt the water move and reached out her hand, "Amy?"
"Yeah?"
"Is Rory with you?"
"I'm here Yal" Rory's voice said. "And I've got Amy's other hand…"
"Okay" the Doctor said, "Onwards and upwards…"
Yalaea could almost hear him smirk. She sighed and kicked her legs, propelling herself upward. Amy, Rory and the Doctor kicked as well and soon they seemed to be moving quite fast. Yalaea thought that the blackness never ended, it just went on and on. Soon Yalaea started to see shapes form before her eyes. First it was the TARDIS and then a strange looking hat. The hat seemed to stare at Yalaea before melting into the dragon from Rhith. Yalaea gasped with fear and the Doctor's hand tightened on hers, bringing her back to reality. "Thanks" she whispered to her left,
"You're welcome." His voice rose out of the darkness.
They swam for ever. Through the never ending darkness until Yalaea thought she saw something. "Did you guys see tha'?"
"What?" the Doctor asked, his hand tightening on Yalaea's.
"I think it's getting lighter…?"
The Doctor looked around, "Maybe…"
Yalaea's eyes felt as though they were popping out of her skull, trying to see any difference. Her eyes glanced down at her hand and she could see a faint glow. "It's definitely getting lighter."
"I think so…" Yalaea heard Rory's voice say warily. Her eyes automatically followed the sound and she saw the Doctor's features come into focus. Yalaea grinned at him and the Doctor smiled back.
"Good to see you again." She said.
"Goo to see you too Yal." The Doctor grinned back. Yalaea laughed.
"We're getting close. I can feel it!" Amy's face came into view as she spoke.
"So can I" Rory said and Yalaea could already see his outline.
Their kicking grew faster as they all wanted to get out as quickly as possible. Soon the light brew brighter and the water around them changed from a deep blue to a clear green.
Yalaea let go of the Doctor's hand and used it to help propel her faster. She sped a little ahead of the others but slowed down when she saw the bars. "No." she whispered "Oh please no!"
"Yal?" the Doctor's voice was filled with sympathy "I'm sorry." He wrapped an arm around her shoulders as they floated just beneath the grate.
