Halo’s entire story is about humanity being genocided because an alien species read the description for a super weapon wrong
Its not high art
But also humans are forerunners. The story just doesn’t make sense otherwise and you have to dive through 17 hoops to justify it otherwise.
I mean its literally as simple as only humans can activate it and ai that should know keep referring to them as forerunners lol
Even the title reclaimer just means reclaiming the shit you made
