The Rikchana (IPA: /ɹɪkˈt͡ʃaːnə/) were the ruling Ardryn tribe in the hills of Thesion prior to their conquest by the Lokrenian army under Tuhoi IV in 277 AD. Their defeat, and the conquest of Thesion, caused King Tuhoi to declare the end of the Age of Dominion at the end of 277 and the start of the Age of Conquest the following year.
