A guild is a group of players that is formed by one player, who then invites other players to join the guild. Some guilds have several hundred players. Some notable guilds are:

The Explorers (a large guild which often organizes events and guides tours)

The Brigade (a guild dedicated to safety)

The Bounty Hunters

Etracea (led by Vvallace and Trogdar, a guild known for its troublemaking)
