LOCATION: Caloris Basin, Mercury

This facility on Mercury has remained untouched by the Vex for reasons unknown. The Golden Age technology at this location remains intact, harnessing energy from the sun and converting it to Solar Light. The Vanguard has denied petitions from the various weapon foundries of the City to research the solar farm (and the resources it continues to collect) until the Warlock orders have finished their surveys. An exemption has been granted to Lord Shaxx and his Crucible: the Guardians are free to use Icarus as a live-fire training zone.
