guild leader recruits new players to the guild and can promote a number of them to guild officers, who can then help with the recruitment and further promotion of officers. All player characters on the same Guild Wars account belong to the same guild. Players may leave their guild whenever they please, but only the leader and officers can dismiss non-officer players from the guild; the leader has the additional power to dismiss officers and disband the guild. Guilds have a membership limit of 100 members; player communities with more than that many members generally create allied sister guilds, often named similarly and using the same tag and cape. Up to ten individual guilds may ally together to form an alliance. Members of an alliance may communicate over a shared chat channel, and visit the guild halls of the other guilds of the alliance. Each alliance has a leader guild that initiates the alliance, the leader of which is also the alliance leader, who may admit or dismiss guilds from the alliance. Each alliance must be devoted to either the Kurzicks or the Luxons, the two Canthan factions (from Guild Wars Factions) locked in perpetual conflict. Players can accumulate faction (reputation) with either the Kurzicks or the Luxons, which can either be "donated" to the alliance or redeemed for certain in-game rewards. The alliances with the highest total amount of donated faction are given control of certain in-game outposts on the Canthan continent; controlling an outpost gives the alliance members access to restricted areas of the outposts, containing, among other things, merchants who sell at a discount. In addition to membership in guilds, a player may be a guest of any number of other guilds. Guest privileges are limited to visiting the guild hall and participating in guild or alliance battles. An accepted invitation expires after 24 hours. Campaigns 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
