The Clans are rebels on the planet opposed to the Omni-TekŪ rule. The leaders of the most important clans sit on the Council of Truth. It organizes the fight against Omni-TekŪ and allot clan charters to the organizations that want to pool their resources in the fight for freedom. A clan charter could give the members a Clan House, a system for electing leaders, special advantages like a clan insignia or even in-game special abilities.
Not every clan fights with arms. Some choose to use political means or a combination of force and politics. There are some people in the clans who wish to find a solution based on co-operation. Other clan members would never talk with an Omni-TekŪ employee. This is the big "disadvantage" the clans have compared to Omni-Tek. They are very divided on a wide selection of important issues. The leaders of the Council of Truth feel that this is the only way to show that the rebels are different from the big mega-corporations they oppose.
