Amélie imagined what purpose these underground passages might have served. Were they remnants of an old sewer system? A forgotten subway line, or something else?
She tried not to think about how deep they were or how far they might still have to go. She'd like to think of it as they're going on a long journey, only it's the one with no map, no destination, and no guarantee of getting out. Sucks to be them right now.
She glanced at Kazuo, who walked slightly ahead. She could sense his unease, mirroring her own.
