The scope of this New Gods run's zoomed in and out - it's balanced " Apokolips and New Genesis being menaced by a force emboldened by Darkseid's death " with " Scott and Barda protecting a child of prophecy from being killed by Orion ", each issue advancing both stories.
The latter story's on Earth - issue #6 brought the former there too, consequently pulling in Superman and the Justice League.
The former'd stepped in because he'd heard Orion and Scott.
( The latter stepped in because someone else heard. )
