Doom approaches in The Harbinger, an expansion for the popular Talisman adventure boardgame. The mysterious Harbinger, a figure of prophecy and ruin, wanders the realm, and destruction follows everywhere he walks. As the demons and plagues of the new Harbinger deck wreak havoc throughout Talisman, three new characters seek the Crown of Command. Their quest is more dangerous than ever before: cursed Followers lie in wait for fresh prey, dire Omens darken the skies, and the terrain itself suddenly transforms as time runs out for the entire realm.
