The Gorak'nar Commonwealth was founded as an Imperium in approximately 7000 BC. Around AD 1865, the Emperor was replaced by the High Inquisitor as leader of the Gorak'nar people, with very similar powers. The Throne of Po'gaenus - named for the last of the Emperors - has been vacant since Po'gaenus the Exalted abolished the Emperorship in AD 1865.
