[quote]I understand where you're coming from, but I feel like your post is a bit misleading. The exos were never human. The exo body was created "for a war long forgotten". It wasn't until afterwards that (and I'm assuming a small but here) human minds were implemented into the exo bodies.[/quote] As you can see I have already admitted that. Originally exos were self aware war machines. Many of the City's Exo citizens live and work alongside their organic brethren. But others fight again, re-forged in the Light of the Traveler to serve as Guardians This is also started in a grimiore. Just like not all awoken are guardians, not all exos are guardians. They weren't originally created to be guardians. Considering they were created for "a long forgotten war" I personally would assume they were created during the golden age at some point before the traveler created guardians.
