Guild Wars: Nightfall takes place on the continent of Elona, Land of the Golden Sun. It is a nation comprised of three great provinces. The island province of Istan is the home of a vibrant people who live among the monuments of an ancient empire. The military province of Kourna, under the command of its great leader, Warmarshal Varesh, hugs the shores of the mighty river Elon. And in the rugged lands to the north, the Princes of Vabbi rule from their opulent citadels. Elona is a land of wealth and power, protected by its champions, the Order of the Sunspears. In Guild Wars: Nightfall, Elona has fallen under the shadow of an evil, outcast god. Against the encroaching desolation of an infernal realm, the people of Elona will need more than a hero to save them, they will need a hero to lead them... for nightfall is at hand.
Guild Wars Factions is the continuation of the epic online battle set forth in Guild Wars, the ground-breaking online role-playing game that took the gaming world by storm in 2005 with its fantastic design, depth of play, and no-subscription-fee model. Guild Wars Factions opens another gateway into the Guild Wars universe, allowing new players to join the community of more than one million gamers already playing Guild Wars and providing veterans with a new world of conflict, combat and thrilling adventure in the mysterious realm of Cantha. As the saga continues, the factions of the empire battle for the realm; players will be able to pledge their allegiance to one of these factions and by their actions determine who the winner will be. While Guild Wars Factions is a standalone product that does not require the Guild Wars to play, gamers with Guild Wars accounts who purchase Factions will be able to play in the both campaigns with their existing characters.
