Kill Grimson the Pale and bring his head to Dalar Dawnweaver at the Sepulcher.
It will indeed take me longer than I had thought to uncover the dark secrets behind the enchantments Arugal was using.
But in the meantime I need you to take care of a slight problem our Darkstalkers have discovered. It seems that Arugal let his magic spread to the Deep Elem Mine in the hills to the southeast.
The mine would prove to be quite a resource for Varimathras's advance.
I want you to behead the tainted foreman of the mine, Grimson the Pale. With his death, the mine shall be ours.
