Prole Sector was a name employed by Daniel, an operative of Politdivision Central, to refer to the supporters of the Interstellar Alliance during the Second Earth Alliance Civil War, in which the Earth-centric government fought against Earth Alliance colonies. This sector of the Earth Alliance was known to hold the members of the Army of Light, founders of the Interstellar Alliance, as heroes, thus leading Politdivision to try to "deconstruct" them via propaganda in an attempt to legitimize their xenophobic, Earth-supremacist policies.
