Note that in the beta apparently there's a bug that removes armor when it is damaged.  The Solo MMO Player ran around without pants for a while until he figured out how to repair them.

Here's an explanation of the various campaigns and the expansion pack for Guild Wars One. from this link which is where you can find the footnote references--http://en.wikipedia.org/wiki/Guild_Wars

"Full games in the original Guild Wars sequence were released in episodes known as campaigns. Players must purchase an individual campaign in order to access the game elements specific to that campaign; however, all campaigns are linked in one game world. Each campaign is independent of the others, with its own co-operative storyline, campaign-specific skills, and competitive arenas. Players owning different campaigns may still interact in shared areas, including trading for items specific to the campaigns they have not purchased. Players who own two or more campaigns may transport their characters freely from one campaign to the other, integrating in to the storyline as a foreign hero.

The first campaign, Guild Wars Prophecies (originally named Guild Wars), was released on April 28, 2005. The Prophecies storyline is situated on the continent of Tyria and revolves around the Flameseeker Prophecy, a prophecy made by an ancient dragon named Glint.

Prophecies was followed by Guild Wars Factions on April 28, 2006, released exactly a year after Prophecies. Factions is situated on the small southern continent of Cantha that is separated from Tyria by a vast ocean. The events of the Factions campaign concern the return from death of a corrupted bodyguard named Shiro Tagachi. Factions features a global persistent war between the rival vassal nations of Cantha; the Luxons and the Kurzicks, and the notion of guild alliances (see guilds above). The continent of Cantha is heavily based upon and influenced by eastern Asia.^[21]

The third campaign, Guild Wars Nightfall, was released on October 27, 2006. Nightfall features the arid continent of Elona, joined to southern Tyria across a vast desert. Nightfall introduced heroes, advanced computer-controlled units that can be micro-managed by players, including the ability to customize their skill layout and equipment. The continent of Elona is heavily based on and influenced by North Africa.^[22]

Scrapping their initial plans for a fourth campaign, ArenaNet has released an expansion pack, Guild Wars: Eye of the North, to the previous three campaigns on August 31, 2007.^[23][24] Not being a full campaign, this expansion requires one of the other released campaigns, and is only accessible by player characters at level 10 and above. Eye of the North therefore does not feature new professions, but contains new content for existing characters: dungeons, a number of new skills, armor, and heroes. Eye of the North is set in previously inaccessible territory from the first Guild Wars campaign, Prophecies. It is intended to be a bridge to the sequel to the Guild Wars series, Guild Wars 2. As a promotion for their online store and Eye of the North, ArenaNet released a "bonus mission pack"^[25] for purchase online. It contains playable recreations of four incidents in the history of Tyria, Cantha, and Elona, and each mission expands the backstory for one of four major NPCs.^[26]"
