The Empire is the main governing force in the Riiamar Galaxy. Founded some thousand years ago, during the bloody expansion from Earth due to overpopulation, it started out ruling only humans, based on the world of Garanth, which is an Earth-like planet covered by one massive city, with towers and buildings miles high.

When humanity encountered aliens, they quickly learned that they were not the dominant force in the galaxy anymore. Some races became allies, others bitter enemies. technology advanced by massive leaps and bounds in only months rather then years.

When Senator Reyzen came to power, he gathered members of the Governing Council, the old government body, and got them to vote for an empire to be formed. this Empire of Riiamar, as they had named the galaxy, would rule everything and everyone. The votes were unanimous, and the building of the Empire began.

Today, about a thousand years later, the Empire has thrived as a whole. The current Emperor, Greiz, has been in power for several centuries, thanks to advanced medical technologies. His methods grow brutal, and subsectors across the empire have dissolved into anarchy and rebellion as he cracks down harder on dissident planets and sectors, unleashing the full might of the Imperial Fleet.

Rumours have also spread of a new menace at the fringes of populated space. This has also added to the rebellion, and to the Empire's iron grip closing tighter.
