Exploring the abandoned subway tunnels beneath the city, you navigate the dim, flickering lights and graffiti-covered walls. As you turn a corner, you see a man, standing silently in the shadows, his face hidden beneath the yellow hood.

The air grows colder, and your pulse quickens. "You shouldn't be here," he says softly, his voice echoing off the damp, concrete walls. He takes a step closer, and the sound of distant, shuffling footsteps makes you realize you're not alone down here.
