Exo

"Ask yourself: what threatened your Golden Age ancestors so much that they constructed the Exos to defend themselves?"

- Card blurb

The Exo are a race of humanoid war machines built long ago for an unknown purpose and fashioned in humanity's image. 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.

Overview
Exos appear unyielding and tireless. Mechanically, they are so advanced that only a Ghost can comprehend their inner workings. In many ways, Exos like to think of themselves as human, or having human minds in machine bodies. Mysteriously every Exo has a number appended to their name. The meaning of this number is unknown, but may possibly signify how many times an Exo has had its memory wiped. Not all wipes are successful in completely removing past memories, though, especially for Guardians and some can gain access to these buried memories by purposefully dying or killing themselves.

History
The Exo were built during humanity's Golden Age for a long forgotten struggle, with the purpose of protecting their creators. The conflict itself has long been forgotten and the Exo remain ciphers, even to themselves, for their purpose has been forgotten as well. But there is one clue to their origins; many Exo experience a dream they call Deep Stone Crypt, or the "place where they were born." It is described as "the infamous subroutine which seeded the first Exo consciousness." Cayde-6's memories stretch further, where he recalls being a human before traveling to Europa to become an Exo, as he "came there in flesh and bone. Gave everything to the ice. Started over. Rebooted."
