Vigunn

 is a Nord barbarian and member of the false Skaal tribe on Solstheim. He can be found either in the Raven Rock Mine or wandering the wilds of the Hirstaang Forest region.

Drastic Measures
Carnius Magius has asked the Nerevarine to deliver equipment to a group of Nords arriving on Solstheim. He's hired them to slaughter the colonists at Raven Rock, making it appear as if the natives did it.

Under Siege
The Skaal have apparently attacked the colony. Falco Galenus and the others were able to push the attacks into the mine, but there are now workers trapped in there. Falco suggests to go in, eliminate the Skaal, and make sure the workers are safe.
