When Rover opened his eyes, what appeared before him wasn't earth.
Nor a natural cave.
It was a massive metal corridor stretching deep into darkness. The walls on both sides curved slightly, their surfaces covered in flickering blue lines like the circuitry of a dying machine. The air was cold and dry, carrying the smell of old metal and an inorganic feeling so uncomfortable it gave the impression of having stepped inside the body of a massive mechanical creature.
Sunako stood near Rover, looked around, then slowly said: "This place... doesn't feel like an underground structure."
Nanoe reached out and lightly touched the metal wall. Blue light immediately ran across her fingertip then quickly faded. She frowned slightly. "The surface is made from a very special material. Not like any metal we've found before."
Selina looked at the long corridor stretching into the distance. "More like a ship's compartment."
Rover didn't answer.
Because he thought the same thing.
