Also, regarding "what even is the Human Order". The literal translation of it is "human principle", which might help understanding more, but to give you the short of it this is how it is described in Solomon (NA TL but word replaced cuz lazy):
In other words, at its simplest you can just think of it as "the law of nature which says humanity must prevail" but also at the same time as "all the magical ways humanity's existence has affected the world". It comes in the form of, among other things, timelines and pruning (remember Alaya, the prayer for humanity's survival, prunes timelines specifically to maximize humanity's progress), and in that regard QTLs are included (as more QTLs are placed and humanity's history grows more "secure", the "Human Order Foundation" grows stronger), Servant summoning, no DAAs, etc etc.
When Chaldea talks about "protecting the Human Order", they're saying they need to protect both the history we've made but also the survival of mankind. If someone says they're "outside the Human Order" it means they're so alien our governing laws basically don't even apply. You get the gist, I'm sure.
