Scarlett's footsteps echoed in the narrow underground passageway, her breathing shallow as she followed Ellen's lead. The tunnel walls were damp, the air thick with the faint metallic tang of rust and something acrid she couldn't place. She cast a quick glance over her shoulder, the dim light from Ellen's flashlight barely cutting through the darkness.
"Are we sure this even leads somewhere?" Scarlett whispered; her voice barely above a whisper.
Ellen didn't slow, her tone calm but firm. "It does. Trust me." She said with her shaky but steady voice.
Scarlett clenched her fists, frustration bubbling beneath her surface. Trust was a fragile thread between them, strained further with every new revelation.
They rounded a corner, the tunnel widening slightly as the sound of humming machinery reached Scarlett's ears. The faint glow of monitors flickered ahead, illuminating the entrance to what looked like a hidden chamber.
