Clans are the largest organizational unit in the Dark Brotherhood, consisting of up to three Houses. Led by a Consul and a Proconsul, Clans often compete against each other for medals, glory and other spoils in events called Vendettas.
As with all shadows, the Shadow Clan itself is neither Dark nor Light. Predominantly Gray, Arcona rules its home territory benevolently and focuses on maintaining a strong military and strict control of the system's underworld. The current Second Clan of the Brotherhood, Arcona has won the past three Great Jedi Wars Please see the website/Wiki page for more information.
