The Rise of the Machines

This can't be Argelmach! Argelmach was killed ten years ago. How can I be sure? I was the one who killed him. He was a despicable dwarf, hell-bent on twisting my life's work to meet his diabolical needs. It seems that the wicked always find a way to escape justice. If this is Argelmach's handiwork then he must be destroyed. I will need samplings of his latest creations. With the proper samples, I may be able to stop this uprising. The creations guard Argelmach in Blackrock Depths.
