Players can form Guilds[5] with other players. Guild creation costs a certain amount of Mesos, depending on the version being played. Guild extensions and emblems, which have separate costs, are also available. The purpose of a guild is to be able to find and chat with others more easily, bond with other players, promote cooperation, and battle using teamwork. Members have their guild's name listed under their character name along with the guild's emblem, if applicable.
