Cavaliers

From publisher blurb: Cavaliers who join the Order of the Wolf devote their lives to hunting something, whether it is a legendary creature (Sir Pellinore and his hunt for the Questing Beast), a fabled treasure (the Knights of the Round Table and their quest for the Holy Grail), or a notorious person (Sir Guy of Gisbourne and Robin Hood). These cavaliers have sworn an oath upon their honor never to rest until what they have sought is finally within their possession. They typically work alone, though small groups of cavaliers hunting the same object are not unknown (and often frighteningly effective.)
