Forerunner/Reclaimer Trilogy

Okay, so why is the second trilogy called the Reclaimer trilogy? That was Chief’s purpose in the first trilogy right? Wouldn’t it be better if the first trilogy were called the Reclaimer trilogy and the second one the Forerunner trilogy?

I would consider the first trilogoy the 'Halo trilogy. Halo: Halo trilogy. Because that trilogy was about the discovery and the distruction of the Halo array.

This is the Reclaimer trilogy, because in this trilogy, this is where Humans reclaim the Mantle.

Well halos 1 2 and 3 are about MC finding halo, and making sure the covanant don’t use it and to stop the flood, Halo 4 5 and 6 is about… MC waking up to fight a new enemy
