Asguardia is the racial homeworld of the Asguardian Dwarfs, and is a moon of a gas giant planet, which it shares with Alfheim, the homeworld of the Star Elves and capital of the United Planets.

Until 145 years before Year 1, the moon of Asguardia was divided into hundreds of self-governing clans each led by a hereditary leader with the title of Moff. In that year, Asguardia united under a Council of the Clans.

After the formation of the Star Imperium in Year 1, the local government of Asguardia passed to the Imperial Parliament, which continued into the era of the United Planets.
