As Captain Ilsa and her team followed the robot through the labyrinthine passages of the underground forge, they were struck by the sheer scale of its operations. The path they took was illuminated by the soft glow of molten metal, casting long shadows on the walls and revealing glimpses of the forge's vast capabilities.
The air was thick with the sound of industry: the clanging of metal, the hiss of steam, and the low hum of machinery operating beyond the limits of human engineering. They passed by factories embedded within the cavern walls, each dedicated to a different aspect of creation. Some chambers were filled with robots meticulously assembling devices that defied explanation, their forms and functions a mystery. Others were vast foundries, where the raw materials of the planet were transformed into alloys unknown to the team's scientists.
