The Solarian Empire', also known as the 'Imperium of Solaris or the Solarian Imperium, is a galaxy-spanning empire. The Empire is ruled by the God Emperor and the Royal Family, which are his long line of Daughters. The empire became xenophobic after an unprovoked alien attack on the home world of Solaris Prime, an event that lead the attacker to extension. though xenophobic of many alien races they hold many auxiliaries and each loyal soldier is granted citizenship after years of service. Solarians do not tolarate crime in any way or form and execute traitors and criminals instead of prisons terms, they are an extremely war-like people and as such hold the largest army and navy in the known galaxy. The greatest thing any solarian can do is serve in the Imperial Legion or the Imperial Navy.
