Chief
Chiefs are the leaders of the guild. They are likely the people who started the guild, but the current chief can transfer leadership to someone else if they no longer wish to be chief. They are the only ones who can change leadership or disband the guild. Chiefs are responsible for setting the ranks of all other players in the guild and setting the rules of conduct within a guild. You control the guild name, abbreviation, invite settings, and shield. When someone requests to join the guild, the message goes to the chiefs and they can accept or decline the request. You can invite players to join the guild or remove anyone else from the guild.
In the event that the guild boss becomes inactive, support can help.
Elders
This is the guild's "Officer" position. You can promote/demotion players from the guild to the warrior or villager positions. They cannot dismiss the chief or any other elder. They can invite other players to the guild, but have no ability to approve requests to join. They cannot promote or demote other players. They do not have access to the Guild UI.
The chief is the only player who can promote another player to elder or demote an elder back to warrior or villager.
A maximum of 2 players can be Elders in a single guild.
Warrior
This is the 3rd tier. Warriors do not gain any special abilities. The only difference between a warrior and a villager is that the warrior's name bar is blue in the member list.
Villager
This is the 4th tier. Villagers do not receive any special abilities. The only difference between a villager and a warrior is that the villager's name bar appears in white in the member list. This is the rank that each new member of a guild joins until promoted to another rank by the chief.
