Obtain 5 Elemental Modules from the golems in the Manufactory of Blackrock Depths and recover the Elemental Golem Blueprints.
The latest SI:7 intelligence on Blackrock Depths is troubling, <name>. It appears Twilight's Hammer is working with the Dark Iron engineer, Argelmach, to create war golems powered by elementals. These golems could prove to be a devastating weapon if used against us.
You must prevent that from happening, <name>. 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.
