This fic explores a lot of dark and convoluted topics and plays with different moralities, which I always appreciate. There is a lot of internal conflict that doesn't come off as preachy or obvious. It's a good character study and fantastic world building as well!
The thing I loved most about this fic, was the author's willingness to follow the canonical plot, while also making very large changes. I've seen a lot of fics in the fandom that take cannon as gospel, and as such, they hardly if at all change the major battles/conflicts. PitViperOfDoom doesn't do this. They are unafraid of changing things to make more sense in their story, something I really admire, as it makes the same old fights feel new and engaging again. It makes you feel like you don't know what's actually going to happen, because if they feel comfortable changing something hardly anyone does, what else could they change?
