The following account was recorded in the agent's log during your transmission: Metal grating presses against my face, umm, a worn, industrial ladder stretches down into this... huge, concrete tube, like, a storm drain or something. The air's thick with the smell of wet cement, it's cold, too, but it's really still... no echoes. I'm seeing... like, triple, and there's a ladder running along the ceiling of this tunnel, upside down, just... suspended there, with water dripping up onto it from the grating. Echo, come on, gotta keep going, it's all... slipping away, it's like my vision's just gonna cut to black, and I'm... uh... done...
