Old Athen is one of the main Clans cities in Rubi-Ka. It was completed in 28850 under the name Omni-2 due to severe overpopulation in Omni-1. In 28860 Omni-2 was partly destroyed and flooded due to the malfunctioning weather control system. Repairs began immediately. October 12 29209 during the first Rubi-Ka'n civil war Omni-2 is taken over by clan forces and renamed to Athen, after one of the clans leaders who died in the attack. Today Athen is a very popular (read overcrowded) Clan city, government and security is provided by the Vanguard. Old Athen is also the only Clan city with Prison.
