History of Eleventh Hour

Dead Orbit Engrams earned by ranking up with Dead Orbit during Faction Rallies, via Arach Jalaal.

This is a legacy-style reward weapon. It is not a craftable or Adept weapon as far as the sources show, and sunset status was not stated by the sources I opened (the fan wiki is the main source). See also Arach Jalaal and the Crucible for the PvP context.
