It...

It all changed when u were 10. Wait, let me explain: ur childhood was pretty normal, some yelling, fighting here and there but nothing unusual. That all changed the night after u turned 10. Ur mum came back from her job which u had no idea what was. You were sneaking downstairs into the kitchen to grab a midnight snack when u overheard ur parents speaking. "I think it's time, honey" said ur dad. "Yes, I have installed the last of the security" said ur mum. then they started walking back to the staircase so u hurried to ur room and lat rigid in ur bed. Ur mum came in and saw u in ur bed so she left. The next day ur parents tell u to get in the car, u have a backpack packed in the back. They say u are going on a "holiday". 4 hours later, u stop at a circular lab-looking place, ur parents say they are just looking around as a stop. U go inside and wander onto a row of cells, they tell u to take a closer look so u reluctantly put ur face on the cold steel bars then BAM! the bars go down and u stumble inside, then they go up again and ur parents say "oops" with a sneer. Some years have passed and it's just another mind-numbing day with the same routine, all u see are the white walls of ur cell. Then u hear screaming, a creature, pitch black with long fingers, it was humanoid and had no facial features except a sharp-toothed smile and 2 glowing eyes. It killed ur parents and unlocked ur cell but all the escapes were locked and u had no way to get out... Forward a few years, now all u eat is black sludge since the food had gone bad years ago, the black creature hasn't come back since that one fateful day. The place is dirty and not cleaned, just there, forgotten by time and left to the dust. Then one day the door is eased open and in comes a traveller...
