Storyline (Nightfall)

Little is known about the storyline of Guild Wars Nightfall so far, only this tidbit from the official Press Release on the Prerelease Bonus Pack:


 * Guild Wars Nightfall takes place on the continent of Elona, Land of the Golden Sun. [...] 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.

 * The realm of Elona has known peace and prosperity for centuries. Its three provinces—Istan, Kourna, and Vabbi—have been ruled separately since the great hero Turai Ossa stepped down as sovereign and left on a pilgrimage into the Crystal Desert some two hundreds years ago. The provinces rely on one another for trade and protection. The Istani navy patrols corsair-infested waters, while the Kournan army—led by Warmarshal Varesh Ossa, heir to the great Ossa line—keeps a watchful eye on the plains should the Undead Lord Palawa Joko rise up again, and the Vabbian princes provide wealth and leisure for all to enjoy.


 * But it is the Order of the Sunspears who truly bind the realm together. This grand alliance of heroes has defended the entire realm since before the terrible years of the Scarab Plague, which nearly wiped out all of Istan and brought an end to the era of the Primeval Kings. Today, the Sunspears are flourishing under the leadership of Spearmarshal Kormir. Their ranks swell and their power grows as new recruits join the Order on a daily basis.
