While primitive races are confined to a single planet or system, most star-faring races are members of a multi-system or galactic government. The greatest empire are vast governments and fleets that control systems in multiple galaxies.

Intergalactic Empires

• The Kree Empire: The once-dominant civilisation of the Greater Magellanic Cloud.
• The Skrull Empire: The fractured empire that dominates the Andromeda Galaxy.
• The Shi’ar Empire: The dominant power of the Triangulum Galaxy and perhaps the greatest power in the Local Group.
