The religion of the Kingdom consists the worship of a pantheon of minor gods as well as space living beasts. The Hydran Kingdom was once conquered by a united Klingon and Lyran invasion force that ruled them for many years from orbital stations due to the methane breathing nature of the Hydrans themselves. During this time, the Hydran Lost Colonies served as the only 'free' group of Hydrans at the time. Eventually, the Kingdom was freed thanks to the aid of the Federation.
