On the strike savathuuns song (why am I still saying savathuuns thong), anyways back on track, Sloane sends you to find a (maybe a few) lost fireteam(s), in which you technically become lost.
Hive require death and sacrifice to live (according to zavalas little flavor text), and what does ghost chime in with...pretty much, yeah well be ok, see ya later.
Tako-3 sacrifices herself (point Zavala), and this always happens...no matter how many times it happens. Tako-3...is dead. Sacrificed to allow 3 guardians to continue on...with whatever the hell theyll do next...but at the same time, her sacrifice technically solidifies the statement, the hive require death and sacrifice to live. So since, no matter what, that three guardians have made it through the strike...means the hive must always exist.
Edit: guess I should just say tako, was sacrificed...going off of how ghost designates her at the end.
Edit:light (saint 14), dark (end of a world/vex/osiris), truth (haven't seen the cabal one yet, but the fallen and hive have possible ending and origin points...they're always in the future simulation at some point. The fallen world was destroyed, the fallen were at the end of the simulation (which, mind you, even if it's osiris' simulation, I don't think he says anything about it not being connected to the vex network, just that the forest is his), so the fallen if the past present and future must exist.)
