What an epic fic, both in terms of length and scope!
I'm entirely with Kelly and Alisanne on the world-building, which is really remarkable, but I also want to mention two things that struck me as I read: 1) this fic really thinks through the relationship between the Aurors and the Order, which of *course* were often at odds with their completely different values and goals. Canon gives us hints of tension, but this fic goes much further, showing us that there are things that can be addressed legally, by the book, and things that can't. I really appreciated that complexity--it's not just corruption or obstructionism that should make us suspicious of the Ministry, but the real limits to what can be done by a bureaucracy. (And conversely, I appreciated the acknowledgement that the Order is a vigilante organization, which is problematic in its own ways.) 2) A fic that takes Moody's incarceration in his trunk seriously! Why are there so few like this? It's one of those odd chapters in canon that's really horrifying, once you start to think about it at any length.
