Parma

Parma (also known as Epsilon Aurigae δ) was a major UNSC colony world located in the Epsilon Aurigae system. By 2591, its population of 144 million was the highest of any second rim colony.
In 2592, a New Covenant battle group attacked the planet to little avail. This would be the third and final confrontation to occur before the United Nations entered the Second Great War in full force.
