Armchair

You panic. You decide to hide behind the armchair, as you feel you don't have the time to hide anywhere else. Only once you crouch down behind it do you notice your mistake. The armchair isn't big enough to hide your entire body. No matter what you do, your toes stick out from behind the chair. On top of that, the entire place is lit up like a bonfire. You're essentially sitting in a spotlight, but it's far too late to move. The naga has reached the floor you're on, and she looks PISSED. You swallow and wait, praying to god that she doesn't find you.

However, it seems as though luck is on your side once again.

The Naga searches the entire hall for what seems like hours. She scans tirelessly, looking for her victim. Five times, she passes right by you. She even looks in your general direction a few times. However, she eventually comes to the conclusion that you must have left the way you came, and barrels out the front doors in a fit of rage.

You climb out from behind the armchair. You're astounded that she didn't see you. You tried to think of why, but nothing came up.

"Perhaps it's something that I'll never find out..." You mutter to yourself.

You don't contemplate for long though, as you have a job to do. You enter the performance hall, and find room #24. The grate is already open.

"Alright, two more floors to go..." You tell yourself and take a deep breath. A few more hours and you should be free.
