The stairway is dark. It feels as if something is stalking her through it. It's unsettling, and vaguely frightening. It makes her hate rounding corners blind, and leaving her back exposed. The area between her wings is starting to itch.
She reaches the next floor, stumbling through the door that leads there, and slamming it closed behind her. Her heart is racing. There's a cold sweat running down her back.
Once the pounding of her heart fades from her ears, she's able to hear an odd, faint squealing noise. Like wheels.
