i mean, these abstracted legend NP`s are "created by the throne" when the hero is recorded and since you get recorded when you get famous enough for humans to notice you, consciously (as in actually famous) or unconsciously(Alaya knows you are important enough to qualify) you could argue that these NP`s are created by humans, since its their minds that create the hero. so they arent Divine constructs
As for why Harpe isnt a divine construct... idk, might have to tackle this from the MECHA history angle. Harpe was used by Cronus to depose Ouranus of his "
procreation facilities
balls
" and position of top dog so it might originally be some shit like a computer virus.
now, idk how well the Mecha history lines up with the greek myth, but Harpe existed before Ares was born and in Nasuverse Ares wielded the "Prototype that all Divine constructs would be based on"(the space battleships beam weapon systems) , so logically NO divine constructs whatsoever existed before this moment in time even if they were crafted by gods?
so my conclusion would be that Harpe was created by the "humans worship/interpretation" of the tale of Cronus taking over Ouranus`s position, and as earlier i was bullshiting that weapons crafted by the throne are crafted by human minds therefore not divine constructs, Harpe being turned from computer code/virus into a weapon by human minds also makes it not a divine construct
