Hey all. A friend of mine once came up with this idea and it kept bothering me. So I'm writing it now.

Chapter 1: The Attack

They were taking their time, walking through the streets of the City to the marketplace. The Doctor was telling Clara about the planet and its inhabitants.

Xouria, a relatively small planet compared to earth, with an even smaller population. This was mostly due to the fact that the entire planet consisted of immense mountain ranges, making it difficult to live there. So instead of many spread out, small cities and towns they built five massive cities. The one they were currently in was the first one built and also the biggest, hence its name being only the City. In the centre of the City towering above everything, stood the Citadel, something between a science and technology facility and a government building.

"Why couldn't you park the TARDIS a bit closer?" Clara nagged. They had been walking for almost an hour now and she still couldn't see the fabled marketplace the Doctor had told her about.

The Doctor sighed. "I wanted you to see the sights, Clara."

"What sights? It's just buildings," she waved her arms at the grey buildings surrounding them.

"Yes, but look at the architecture. It's a mixture of designs. Where we landed everything looked really modern and the further we go towards the centre the older it gets. It's like going back in time." He changed course, taking narrower streets. "Look at the people too. Their clothes, a combination of old and modern styles."

Clara payed closer attention to her surroundings. Sure enough she noticed the change in the buildings and the different styles of clothing. How the Doctor saw the differences in the clothing when she didn't, was a mystery.

"Ok, it's quite interesting," she admitted.

"Their tools, technology, even their weapons. A combination."

"I get it now, Doctor," she laughed. "So how much further to the market?"

They turned a corner, coming to a standstill in front of a giant warehouse structure. Inside they could see hundreds of wooden stalls and little shops, each selling an assortment of goods. Unknown aromas drifted from strange foods by the food stands, and content chattering filled their ears.

"We're here," the Doctor smiled down at Clara.

Once inside, they drifted from stall to stall, frequently stopping when something caught their attention. Leaving the Doctor where he was arguing with a woman over some wristband contraption, Clara wandered on. It was a fascinating market, probably the best one the Doctor ever took her too. There was almost too much to see.

Suddenly people at the far side of the building screamed. Those around her looked up in confusion as people stormed past, shouting at those standing still, to run. A series of explosions outside the building shook the ground. In the distance, a siren started to wail, sending everyone into a panic.

Clara swung around, trying to avoid the fear stricken mass while searching for the Doctor. She couldn't see him, fleeing people blurring past her blocking her view.

Someone took her by the hand and pulled her back through the people. Spinning around, she was extremely grateful when she saw the Doctor. He led her to one of the side doors, but stopped as they saw people there getting shot down by soldiers clad in black. He pushed her behind a stall as the soldiers took notice of them, raising their guns.

"They're surrounding the building," the Doctor shouted over the gunfire as he ducked next to her and took out his sonic.

Something red under his jacket caught Clara's eyes. "Doctor," she whispered, staring at his side.

"What?" He followed her gaze and saw the blood seeping through his shirt. Shifting the material around the wound, he looked up at her. "It's fine. Just a scratch." He moved away as Clara started to protest, carefully looking around the corner of the stall. His eyes grew wide.

"Clara, get down!" He threw himself on top of her, shielding her as everything around them shattered.

She faintly registered muffled screams and muted gunshots. It sounded as if the noise travelled through water before reaching her throbbing eardrums. She felt disorientated. Opening her eyes, she saw nothing but dust and debris. The stall behind which they took cover had been blown to bits, the rubble of nearby stands littering the dust covered floor. She felt something shift next to her and heard the Doctor groan and cough.

"Doctor?" She coughed, her own voice sounding distant. Slowly the fog cleared from her head and the sounds returned to normal. They had to get out of there, back to the TARDIS.

The Doctor was face down next to her, covered in dust and splinters. He didn't move when she placed her hand on his shoulder. She noticed a dark spot on the back of his head, the hair caked with blood.

Something must have hit him in the head when that bomb or whatever exploded, she thought.

"Doctor?" She gently shook him. "Doctor, come on. Wake up." Panic crept over and she shook harder.

The Doctor stirred and groaned, coughing as he pushed himself up onto his elbows.

"Clara, we ha-" he interrupted himself by coughing again. He struggled to his knees.

She helped him up, supporting his weight as they stumbled through the chaos. People were running in all directions, screaming, shouting, trying to get out. Some weren't so lucky, having been shot and left to die between the burning remains. Other soldiers were desperately trying to drive back the attackers. She didn't know where to go, she needed the Doctor to take the lead. If she could just get them somewhere safe, maybe he'll recover enough then and get them out of here.

She saw a little shop not far away. It could offer more protection than the wooden stalls. They reached the building as she felt the Doctor's legs buckle, almost bringing her down with him. She helped him up again and got them through the door. He steadied himself against the wall while she jammed a chair under the door handle.

"What do we do, Doctor?" She turned around to see him sliding down the wall, his breathing shallow and eyes closed. One hand clutched his side as the other searched for something in his pocket. She crouched next to him and lifted his hand. With the pressure gone the blood trickled out of the wound, staining his shirt even more. He grunted as she pressed her hands over his on the wound. A sound by the door made her look up. She felt something cold and metal clasp around her wrist.

"Vortex manipulator, allows for space and time travel," the Doctor said before she could ask. "This one's broken though, can't teleport us out of here." He patted his pockets. "Where's my sonic?"

"The explosion, it must've got knocked out of your hand." They glanced at the door, hearing voices outside.

The Doctor shook his head. "No time anyway. It can still time travel. Don't like it, but it could be our only hope."

Clara watched as he entered something into the small keypad. His hands were trembling, the red blood starkly contrasted against his pale skin. He's losing too much blood.

"I'm sending us into the future," he said as he typed. "Hopefully things would have died down by then so we can get to the TARDIS. Just, hold onto me." He said quietly.

They jumped as the door splintered into pieces with a loud crack. Three soldiers moved in, one immediately going for Clara. The Doctor activated the vortex manipulator.

She struggled against the soldier as he grasped her shoulders and hauled her back.

"Doctor!" Clara reached for his outstretched hand as the other two soldiers grabbed him.

She watched helplessly as they pinned him to the floor and secured his hands behind his back, before she vanished, taking the soldier holding onto her, with her.

I plan on uploading a new chapter every week. Please leave a review and let me know what you think :)
