Golden Age of Viltrum

The Golden Age of Viltrum is the earliest chronicled period in Viltrumite history, during which the Viltrumites emerged on their homeworld of Viltrum under their first and mightiest emperor, Argall. It spans both the height of the Argall Era, the golden age of their civilization, and the opening of the Thragg Era, the empire's coming age of expansion.

Argall's origins are lost to history, but on becoming emperor he founded the Viltrum Empire, and a fellow Viltrumite began raising more cities, giving rise to figures such as Thaedus, Conquest, Kregg, and Thula. Under Argall, revered as the wisest and strongest ruler, Viltrum grew into the most advanced civilization the universe had ever known. Ages later, Thaedus came to recognize the emperor's cruelty and became the first Viltrumite to rebel, assassinating Argall and fleeing the planet to escape execution, an act remembered as the Great Betrayal.

With Argall dead and his rightful heir unknown, the Viltrumites descended into a savage civil war, the Great Purge, that cut their numbers in half. From the ashes rose Thragg, trained from birth to be the strongest of their kind, whom the Council named Grand Regent. His mandate opened a new era: to expand across the galaxy, hunt down Argall's lost heir, and destroy Thaedus for his treason.
