The way this all connects back to the Guardians having no memories on initial revive is because they’re not the same person. In this theory, a Guardian would simply be based on the corpse their Ghost found. Ghosts don’t bring back the dead, they just restore bodies and place their home made intelligences within said bodies. And since this intelligence is newly born, of course it wouldn’t have any memories of it’s first life. First revival is their first life. One might bring up the fact that Exo actually do have memories from their first life if they go digging deep enough, but I think this only strengthens the Intelligence Injection theory. Here’s why; ​ One trait unique to the Exo is that they do retain memories from their first life, however fragmented they seem to be. Its possible this has to do with initial revival of the Guardian. While the fleshy bits of their Human and Awoken counterparts rot away while they were dead, Exo hardware has a bit more longevity, likely being composed of silicon or some semiconductor alloy. Ghosts who pair with Exo likely end up recovering considerable amounts of stored memories when they first scanning their bodies while building their spawning templet. And every time they inject their Guardian’s mental profile into the body, the two existing memories end up clashing, causing fragmented memories and unknown faces in the Deep Stone Crypt to appear. This could also be the reason why Exo Thanatonauts will often have visions of their ‘first life’, rather than the more spiritual dream like visions that are common within the Warlock coven. Because they’re experiencing their body’s memories as their conciseness exists and reenters their physical form. ​ To further this notion, compare typical Exo memories to two Guardians with the shortest time spent dead; Himura Shinobu and Shin Malphur. Exo have steel traps for minds, locked tight in a cage of metal but it keeps it’s contents intact. The two humans, however, don’t have much intact at all. Shinobu has absolutely no memories from before, despite being brought back within the same day. Shin has only the vague memory of his parents being taken away by dregs, making him one of the only known human Guardians who can remember his past. The key difference being that Shin was revived within a few minutes after death while Shinobu was brough back later in the day. Keep in mind that it only take a few minutes for all the cells in the brain to die post mortem, so in Shinobu’s case, her entire brain would’ve gone offline in the few hours before she was brought back, but Shin’s brain could’ve still been activity between his death and his revival. Meaning that so long as a mind, artificial or not, still has information swimming around in it, that information will be inherited by the Guardian it becomes. ​ There’s also the curious case of the trapped Guardian on the Almighty. For those who haven’t heard, during a recon mission, a Guardian sprung some sort of trans temporal trap, freezing him in place on the Almighty. His Ghost is distraught because he can’t revive him at a different location like he could if he fell off the Rig on Titan. In this case, the Ghost can’t simply spawn another body for it’s Guardian because the Guardian’s metaphysical being is what’s trapped, not the actual body. It’d be like if you nailed the puppet’s strings down. The hand (Ghost) can still more around, but both the puppet (the Guardian’s body) and it’s controls (the Guardian’s essence) are still stuck where they are. So long as that trap has got him, he’s as good as nailed in place. ​ Thats about all I have on this. Hope is wasn’t too exhausting to read. ​ ​ tl;dr -Guardians aren’t actually people resurrected with amnesia. They’re a new entity made by the Ghosts based on dead people. -Ghosts make synth bodies that Guardians pilot. -When Guardians die, they go back into the Ghost, awaiting the production of a new body for them to pilot. -Dead Exo have memories stored within their bodies. When a Ghost makes that body a Guardian, those memories are permanently apart of the Guardian’s synth body, which can end up clashing with their essence. Hence why Exo ‘got problems’. -If a Guardian gets trapped by extensive means, like that poor dreg on the Almighty, their Ghost can’t kill them and revive them elsewhere because the Guardian’s actual essence is what’s been anchored, not just their body. ​ tl;dr for the tl;dr -Guardians are stored in the Ghost.
