"Which colony would I like to retire to? The one where the sun has the decency to set at a reasonable time."

— Jon Grissom.

Elysium (formerly known as Paravarvar II to the Protheans and Starkeep to the Inusannon) is the second planet in the Vetus system of the Petra Nebula. Before 2186 CE, Elysium was one of the Alliance's most successful colonies, many calling it "Earth 2.0." After the Writ of Solidarity, it became the Dominion's wealthiest colony.
