He sat at his worn desk, alone as always. The pencil in his hand danced around his notebook, lines and shapes bringing the paper to life as his mind wandered. All he had for company was the ticking of a his father's clock, and the eerie tones of his mother's record player. With every tick of the metronome, new line was added to the page, forming a maze. He drew a new maze every day; his master had to keep changing the layout to prevent anyone from ever managing to escape. Hundreds and hundreds of pages of notebook paper were piled on the shelf in the corner, and he had memorised every one. 
 
 A new subject entered the maze at midnight every day. Just plucked from their lives and dropped into the stone walls, the outside world oblivious that they had ever existed. No-one had ever escaped, which is why he had kept his job. The first person to escape would be granted whatever they wanted by his master - so he had never made an exit. 
 
 At 11:56PM, he had finished tomorrow's maze. He leaned back in his chair, contemplating whether his work was truly for the greater good, and whether he should give someone the chance to finally beat the maze. As the record player stopped at 11:59, he made up his mind. He grabbed his pencil and went to erase just one small segment on the oter edge. 
 
 The clock struck midnight. As the chimes echoed in the back of his mind, he found himself staring down at a hard stone floor, pencil still in hand.COnfused, he gazed around, unaware of his new surroundings. As he walked through the halls, he began to feel a sense of familiarity to this place. He tripped over a pair of skulls, and the realisation came crashing down on him. 
 
 He was in the maze. 
 
 And as always, he had never made an exit.
