The Bear Hunters

If you leave from pre-searing Fort Ranik and go South-By-Southwest, you'll come across a band of hunters. They will challenge you to find and kill a bear, then return, within 3 minutes. The reward is a mug of Hunter's Ale.

Note that this "quest" will not generate an entry to your Quest Log and also not show any objective locations (i.e. where to find a bear) on your map.
