They knew she was in the building.
Maggie cursed herself as she ran down the stairs, trying to evade the searchers. She supposed she'd done it to herself, letting curiosity get the better of her. She'd known something was going on in the old building on the outskirts of the city.
Sometimes at night she would walk outside, and find the highest point she could reach to look at the stars. There was too much light pollution near the center of town, so she'd started wandering farther, searching for just the right spot. She'd visited the open field nearby the old, abandoned warehouse nearly once a week, and in that time had begun to notice something... off.
She thought it was imagination at first, that the sounds, the lights were just wishful thinking, her mind overactive and grasping at any hope of something out of the ordinary. She thought investigating would finally put those ideas to rest. She'd expected some danger of course, and had picked up a piece of pipe... but she'd expected a rather more mundane danger than what she'd found.
She had no idea what was chasing her, but the man-sized, wide jawed creatures had caught her scent, or heard her,,, One way or another they were trying to find her in the ill-lit maze of old corridors. The building was huge, but they were being unnervingly systematic, covering the exits, splitting up... these were no beasts, and their tactics were dangerously efficient. She evaded them as best she could, but found herself forced down stairwells in search of an exit, and was now fairly certain she was trapped in the basement. She didn't think hiding was going to work, but she fought down panic as she skittered through the hallways, old florescent lights flickering on and off in the ceiling.
It was so dark, and she was in such a hurry, she nearly missed it. A chance glance through a half-open door brought her to a halt, even though she could hear her pursuers drawing closer behind her.
In one corner of a darkened, dust-filled room stood a tall blue box, the windows glowing faintly from the inside. She darted in the room, praying that this wasn't some discarded piece of history, because if it was she was quite trapped; the room had no exit. Desperately, she ran to the box, the beautiful blue box, and grabbed at the door in panic. It was, she very much feared, her only chance to come out of this alive.
