Dirty, dangerous, pristine, and opulent - welcome to West Marque. The sun is slowly setting on the golden age of chivalry in West Marque. The kings are gone, replaced by Marshals. The 'knights of the realm' - the Fifth Wheel - no longer wear suits of armor or carry gilded swords. They wear badges and carry guns on their hips. Their old enemies, the Dead Priests, are ghosts of the past. John Gray, a member of the order of the Fifth Wheel, is hard on the heels of the nefarious gambler James Gallant. However, his pursuit is interrupted when unexplained orders arrive summoning him to Jonah's Sword for an Oath Swearing. That Call marks the dawn of a new conflict for the High Seat of West Marque, a conflict that threatens to awaken the ghosts of the past and mark the end of the Order of the Fifth Wheel.
