"So where are we going to next?" Clara asked. "Ah! Yes, next would be the planet Perspexis, in my opinion one of the top 5 most pretty places I have visited. Lush greenery, huge waterfalls, rainbows, they even have this animal called a Qwadcon, which looks rather like a skinny white rhinoceros." "Don't you mean, a unicorn?" "Don't be silly! Those things only exist in fairytales." "Ah, right."
The whine of the TARDIS engines slowly died down, as a loud thump was heard, signalling its arrival. "And we're here!" The Doctor exclaimed, flicking a few switches and running towards the doors. Clara followed. He opened the doors, and they stepped out.
Instead of a forest, what they saw was a giant facility, made of concrete and metal, with smokestacks belching out smoke of myriad colours and a huge wall around its perimeter. Along the top of the wall, armed guards patrolled with the help of several robotic drones.
"Some pretty place." Clara said.
