Galactic Imperium

The Galactic Imperium, sometimes latinized as Imperium Galactus, is an autocratic Empire based in the Western Arm of the Galaxy known as Convergence. 
Established from the former Galactic Union following a military coup, the Galactic Imperium borrows many of it's traditions from the old-Earth Roman Empire. Formed under the leadership of Tiberius Kaiser, who holds a fascination with old Rome, the Galactic Imperium expanded well beyond the borders of the Union and added many species to its influence. Ruled from the Imperial Homeworld of Earth, the Imperium is administered by the autocratic ruler known as the Imperator. 
The first and current Imperator is Tiberius Kaiser, known as Kaiser I
