Uzkular

I have cut and dried the corpsetallow over a fire and mixed it with silver powder. When set ablaze, the mixture emits a smoke which draws out uzkular that is hidden. Powerful liches hide beneath the earth while vampires mask themselves as animals, but where they linger too long corpsetallow grows, as if it feeds off of the very undeath that they consist of. Take this to the location where the corpsetallow was growing and use it, my sense is that the plateau above the ravine is where our unwelcome guest is hiding. The raging battle in the canyon below as the Oathbearers battle over Ironskin Skar must fuel his power.

Travel to the bluff overlooking Ironskin Skar and use the corpsetallow mixture on disturbed earth to force the undead being to reveal itself.
