Chief Engineer Hinderweir wants you to take the strange smelling powder to Ashlan Stonesmirk, the explosives expert at the Mo'grosh Camp.
If my suspicions are correct, this is some type of explosive powder. This must be analyzed by an explosives expert so we know just what we're dealing with here.
There's only one man for the job. Ashlan Stonesmirk was assigned to monitoring the ogres at the Mo'grosh Stronghold to the east. Head that direction and locate him so that he can shed some light on what this substance is.
