1. Guardians cannot age or get sick, but they can die permanently if their Ghost is destroyed. 2. Normal people [i]can[/i] become Guardians, but they are labeled as renegade and dangerous (e.g. Shin Malphur). 3. I believe the first Exos were either seeded with human consciousnesses or were the product of one of Dr. Shim's team's proxy bodies. 4. The Last City has no official language, but is a melting pot of all surviving civilizations and languages. 5. Based on research and calculations, it appears the City is located somewhere in the Andean area, likely Chile or western Argentina. 6. Old Chicago was lost in the Collapse, and is now a ravaged swampland. 7. The Awoken were born towards the end of the Collapse, as the Traveler's Light pushed back the Darkness. 8. Your Guardian was most likely just an average person/Exo, but it is likely that he/she used to be Dr. Shim, seeing as the Archive called you that, and Shim's gender was never stated in the grimoire
