When you pick up the metal rod, the glowing eyes of the Iron Golem immediately turn toward you as if awaiting your command.

"A control rod," Greycane says with awe, peeking over your shoulder.

The rod is light, barely heavier than a coin, and made of a single piece of strange metal. Within the sealed scroll you find a basic set of instructions on how to command the golem followed by a single warning.

"Do not remove the muzzle."
