Being either a studied move, or simply lacking content, ArenaNet and NCsoft were really cryptic when it came to revealing information on the upcoming Guild Wars Nightfall expansion. Even with the Guild Wars Nightfall PVP Preview Event the past weekend, where players were able to create characters using the anticipated Paragon and Dervish professions, details are scarce to say the least. Developers announced today a retail package to fill in the gaps, providing players with a curious first look at future content. The Guild Wars Nightfall Prerelease Bonus Pack is expected to hit store shelves on September 15.

We also learn more about the history behind the upcoming expansion: "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."

The retail box features a "Play Now" trial key, for a 10 hour period over 14 days of play within the Prophecies and Factions universe. There will also be a Guild Wars Nightfall Bonus Key, providing one additional character slot for a Nightfall account. Two exclusive items for the new professions are also included, a Firey Sunspear of Shelter for the Paragon and an Icy Soulbreaker of Enchanting for the Dervish. But the bulk consists in a mini strategy guide, concept art, screenshots, in-game renders of characters and items, preview trailer, wallpapers, lore, music and a quick reference card. All being said, it's just a matter of price now, since it's agreed the preview pack only has limited value to offer.
