Greenskin Hunters
From Heathen's Gap Wiki
The Greenskin Hunters were a gang of dwarven bounty hunters active until 4626AR who only accepted contacts against giants, goblinoids, and orcs.
They found work in northern Nirmathas by fostering a reputation for being mean, hard fighters, who could be trusted to finish the job or die trying - as long as there was good coin offered. Guthrum travelled with them for a time.
