Due to the lore, I've found an interesting topic surfaced by theory. A theory that the "true Humans" do not respect, support, nor accept the Guardians as their protectors.
Update: I forgot to include that there are some forms of Information referring to Guardians such as Saint - 14, whom was actually much respected and loved by the people of The Last City, but due to his obsession with the downing of the Fallen through a long crusade, he is no longer commonly mentioned, but only as a legend now.
Nevertheless, we've gotten some pretty good feedback regarding as to why. Maybe the "living Humans" see us as something tyrannical?

I saw no reference of any of it in the game, or even light hints towards it. Normal people in the tower walk and interact freely. Most of them don't even appear to have a job vital to tower function, so who knows, maybe they just motivated enough one day to climb the stairs. Bet the rest of the city is mad because the elevator is out, since there's real mention of city citizens not liking the people in the tower, let alone any kind of motivation as to why they would feel that way. It's not like they used the Hammer of Dawn or anything. [spoiler]Be careful with the flashcards. They can lead you down paths that never existed.[/spoiler]
