The town hall is run by Mayor.
When players speak with the mayor they are given an option to make their town account wide. This means that other characters on the account will have the option to start with a shared town or a make a new one. Existing characters can also join the shared town by purchasing The Transfer to Account-Town Document from the The Legendary Wizard Soule. Account wide towns make it possible for characters to make use of the Shared Vault.
