Empire of the Sun
An ancient empire led by a legendary Worcen warrior that ruled roughly a tenth of the galaxy for 1,500 years, primarily south of the Black Horizon.
Founded roughly a century after the invention of the Horizon Drive, the Empire of the Sun introduced the wider galaxy to the Korgen, Voresh and Tomakk races. In 19,500 BAF it fractured into several successor states, including the Empire of the Eternal Star, the Children of the Sun and the Empire of the Dawn.
