A guild is a player-founded and player-run organization within the game. Guilds, like the people who form them, have many different modes of operation and goals. Some guilds exist purely as a social network of players who enjoy gaming together, while others work long and hard to reach end-game content and to become rich and powerful (see Uber and Leet).
Guilds are given various perks by the game, depending upon their level. Some of these include discount housing and mounts for a guild's members, various prefix titles dependent upon the member's city allegiance, guild raids, the ability to purchase and display cloak heraldry, and the ability to make status purchases from city vendors.
