Impera

Description
The small planet Impera is a hothouse of helium and argon, the latter a product of decaying radioactive materials. Robo-mining was once lucrative here, but like the rest of the solar system, the only remaining veins are inaccessible by cost-effective means.

The planet is named for Atrin Impera, the "turian Machiavelli," whose ambitious political philosophies led to her reign as regent in the continent-spanning Nialin Empire for more than a decade. She famously combined citizenship tiers with a meritocracy, rather than a caste system, which served to strengthen her empire. This practice fell in and out of favor for centuries before its revival early in the turians' age of nation-states.

The Reaper invasion largely ignored Impera, sending only a token force to destroy the scientific equipment around the planet.
