Imperium (Traveller)
The Imperium is a series consecutive fictional galactic empires in the Traveller universe.
- The First Imperium was an empire of the Vilani.
- The Second Imperium (or Rule of Man) was formed by the Solomani as after they conquered the Second.
- The Third Imperium arose after a period known as The Long Night, when a small federation of planets known as the Sylean Federation re-absorbed the worlds of the previous empires. The early years of the third Imperium is the setting for T4 Marc Miller's Traveller. A well established Third Imperium is the setting for Classic Traveller and Traveller20. MegaTraveller and GURPS Traveller is set in alternate timeline where the Third Imperium did not collapse.
