Argus V

Located on the outskirts of human-inhabited space within the Cygnus Shell, Argus V is the sole habitable world in its system, one never fully colonized for a number of reasons. Difficult to reach due to its interstellar quirks, and often ravaged by powerful mega-storms, the planet was notable for housing secret ONI Section 3 research facilities, and training facilities for SPARTAN-III Delta Company.
