Guild

A guild is a group of players in a single, permanent social channel. A guild is shown by the nameplate above a character's name. Guilds have various advantages that "unguilded" players do not. For instance, at higher guild levels you can access a guild shared storage.

Guild Points
Guild Points are required to advance a guild's level and are through running dungeons -- they are gained through the completion of both dungeons and commissions, and the empowerment cost of a dungeon is equivalent to the guild points gained upon completion of that dungeon, regardless of whether or not the player has any empowerment points remaining. The amount of guild points that a guild has may be checked at Deckard of Carderock Pass, however, the guild menu has been known to update irregularly and, on occasion, revert to a former state, so the points listed may not be accurate.
