The TARDIS began fading in, materialising in a cramped storage room. The space was filled with containers filled with overflowing wires and electronic equipment making the already cramped room feel smaller. The Tardis finished materialising and the doors swung open and out stepped the Doctor with Ruby Sunday trailing behind him. Ruby looked around at the dimly lit room with confusion.

"Doctor, where are we?" Ruby asked, closing the doors to the TARDIS behind her. The room was silent and Ruby's voice echoed and bounced off the walls of the room. The Doctor ran his hand across the dusty wall and looked back at Ruby.

"We're on a spaceship," he wipes his hand and looks back at Ruby. "Well, the closet of a spaceship." The Doctor replied walking towards the door, his footsteps echoing. "We got a distress call but it was cut off before I could hear anything." The Doctor opened the door, which slid to the left, and the two of them walked out.

They both squinted their eyes as they entered the main room. The Doctor took note of his surroundings. The large room was lit up by bright columns of light in all four corners of the room. The roof was patterned with hexagons lined with orange, in the middle was two grey circles, and on the far left side of the room was a control console. The Doctor walked over to inspect it. The control panel was broken, the whole right side was caved in and the screens were cracked. The Doctor pressed a button only to be met with a burst of sparks which made him jump a bit. Ruby looked around and noticed something strange with the room.

"There are no doors except for the closet," Ruby pointed out. "Is this the whole ship?" The Doctor turned around and looked at the room. He then noticed that the grey circles in the middle of the room were mirrored on the roof.

"Maybe…" The Doctor reached in his coat pocket and pulled out his sonic screwdriver. He pointed it at the roof. Suddenly, one of the circles on the roof split open and a small platform with handrails and hover engines underneath it descended to the ground with a humming sound. "Ah!" He exclaimed. "This place must be a vertical space station. Built for observing the universe to discover all its secrets." He walked onto the platform and looked up. There were hundreds of floors and the Doctor didn't know where to start. "We need a map or something." He concluded. Ruby noticed that one of the tiles in the room was slightly hanging, revealing a compartment.

"I think those things are storage spaces." Ruby said, pointing at the tiles. The Doctor pointed the sonic screwdriver at the tiles. One of the hexagons began descending, revealing it was actually an orange pillar, and on the side of the pillar was a hollowed out section with a blueprint. The Doctor took the paper and unrolled in, revealing it was in fact a blueprint of the ship.

"Would you look at that!" The Doctor said proudly. "Got it on the first try." The Doctor and Ruby looked at the blueprint to try and figure out where to go. "Now," the Doctor started. "Looks like every floor has four rooms except for this one and the control room. So, with 112 floors, we have 552 rooms including the main ones. We should start at the top, the control room, to try and find the crew." The Doctor and Ruby stepped onto the platform. The Doctor pressed a button on the elevator's control display and the platform began humming. "One more thing." said the Doctor. "These elevators tend to travel at high speed so hold on." On cue, the platform shot up like a rocket, flying past floors in a blur. The air rushed past them as they neared the top of the ship. Ruby held on tight to the railing and her and the Doctor screamed and laughed.

The platform began slowing down as they reached the top floor although it stuttered near the top making the two of them worry they might fall any second. Thankfully it didn't and the two of them stepped off. The control room was quite a bit larger than the first one, but apart from that the design was pretty much the same. The only difference being that the roof of the room was replaced with a large glass dome window and orange support beams. The window showed the stars outside which left the Doctor and Ruby in a state of awe, for around two seconds before realising that the room was a complete mess. In the room there were desks flipped over, machinery smashed to pieces, and someone had written on the wall.

"Not a Sound." The Doctor read from the scrawled words. They looked at each other in confusion and fear. The Doctor looked around and noticed that one of the computers was still working and showing the ship's data.

"Where to now?" Ruby asked, not taking her eyes off the words.

The Doctor walked towards the computer and looked for the most recent activity. "It says here that one of the rooms on floor 38 was opened half an hour ago." The Doctor jumped onto the platform.

"Floor 38 it is!" Ruby replied following the Doctor onto the platform. "Doctor?" Ruby asked. "What about the writing?" The Doctor looked at the writing, then back at Ruby. The Doctor didn't know what they were going to find, but he knew he had to put on a brave face.

"I guess we'll have to keep it down then." The Doctor pressed the elevator's button and the two of them slowly started to descend, leaving the room empty.

The platform came to a slow descent as the Doctor and Ruby approached the 38th floor. When it stopped the humming sound the elevator made echoed around the room. The room had four doors leading to their respective areas. However, one of the doors was badly damaged and the storage compartments on the roof were sticking out slightly. The room had tables situated all around and there were plates set out for a meal, however all of them were cracked or shattered. The Doctor and Ruby stepped off the elevator and walked around the room. The Doctor picked up a shard of a plate. Inspecting it he found it had no blood but he noticed something about all the plates.

"These plates are all broken the same way." The Doctor concluded. "All the cracks are facing away from the centre of the room." The Doctor moved to the centre of the room and spun around, looking at all of the plates. "If I had to guess, I'd say they broke from vibrations, from sound."

Ruby walked to the centre of the room to join the Doctor. "But how would-" Ruby was cut off by the sound of buzzing from a laser pistol pointed at the back of her head. The Doctor had heard it too and was about to say something when he was stopped. The two of them slowly turned around to face the person who had somehow snuck up on them.

"Don't talk," the perpetrator whispered. "Don't talk, don't move, don't scream"
