The Shattered Hand has discovered some disturbing information in Blackrock Depths. It appears Twilight's Hammer is working with the Dark Iron engineer, Argelmach, to create war golems powered by elementals. These golems could be a great advantage for our enemies.
It is your duty to prevent that from happening. Find the Manufactory in Blackrock Depths, capture the blueprints he's using to make those golems, and recover the elemental modules he's using to power them.
