The Thralean Tyranny was a despotic client state of the Holy Xaronese Empire. The Tyranny underwent a period of isolationism after accepting Xaronese suzerainty. Common Thraleans were led to believe they were the most advanced race in the Teggedon Spiral. This isolationist policy was overturned in the 41st century when the new Tyrant, Vaessor, revealed the truth to his people. He also decided to send his youngest son, Girrou, to Xaron to become a proper Xaronese nobleman in the hope that he would be an advocate for his people in the Xaronese imperial court.
