Mouth of Miasma

Blasted greenskins! It's not enough they slaughter us by the dozens and deface the fallen, now they're mucking about with our ale! A pack of those vermin started taking pure dwarf-brewed ale and turning it into rotting swill by mixin' it with mushrooms! Dunhilda keeps sayin' we're here for the brightstone and t' let the greenies stay distracted over their experiments, but I say it's a crime that can't be borne! I've spent years perfecting my brewin' skills, but beer ain't all I can make! I've got a little somethin' that should see vengeance paid, but I'll need a hand gatherin' up the ingredients.

Head into the Tar Pits, and gather samples of Rotweed for Thorgrund Forgehand. Return to Thorgrund at Dunhilda's Lads when finished.
