Aremis is a terrestrial planet in the Vega system, United Empire of Earth (UEE). It is famed for its set of rings, which are sharply defined by two shepherd moons that orbit the planet on the ring's inner and outer sides. After being minimally terraformed, it was initially settled only by the military to house Army, Navy, and Marine bases. Vega II's population expanded in SEY 2737 when refugees fleeing the Vanduul flooded the system after the Fall of Virgil. Over the next two centuries, the population steadily rose and the planet was on track for recognition as of 2945. The Senate formally recognized Aremis in late 2945, one month after the planet was attacked by the Vanduul in the Battle of Vega II.

Today, while it is still not fully recovered from the attack, Aremis has both a strong military presence and a growing population of native-born civilians and descendants of refugees. The city of New Corvo has developed into a center for commerce and experimental cuisine.
