Kill 6 Ice Claw Bears, 8 Elder Crag Boars, and 8 Snow Leopards, and then return to Rejold Barleybrew in Brewnall Village.
I have a cask of Evershine handy, but...can you do me a favor? Brewnall village could use a hand against the wild animals that wander the nearby snows. Sometimes they wander close.
We're not afraid of these bears and cats and boars - no self respecting dwarf would be - but if you can take care of those animals for us, then we'd have more time for our crafting and brewing.
