To my surprise, there was nobody inside the command node. Even though I called it a command node, it resembled a metallic command center, a round dome of gleaming metal with windows, sensors and other devices. Inside was similar, but instead of sensors, I saw consoles, displays and a single chair in the middle.
No wonder they called it a command node. It was the command center where a single commander sat, controlling the Steel Golems from the various interfaces spread all around him. Already I recognized one of the holographic screens as a theater of war, representing the interior of the cavern in a digitalized map. It was mostly covered by the fog of war, particularly the areas where there were no Steel Golems around to provide vision, but it was otherwise recognizable.
