Greygore Boomhowler is a veteran trollkin mercenary of countless wars. A fellcaller like his sister, Admiral Thorga Boomhowler of the Brineblood Marauders, Greygore is skilled at using his powerful voice as a weapon. As the world has grown stranger and more dangerous, Greygore has had to travel farther afield seeking work, extending his ample ring of contacts across the whole of western Immoren and beyond.
