(Edit: To be clear, I wrote all of that before I got to the somewhat-uncomfortable insertion of Indian class-system stuff in the most recent chapters. I think it's just not well-thought out on the author's part ("Ah, look at this exotic other country's caste system! It will be great for my fantasy novel!") but the level of cringe is pretty bad. About the same as if someone had used "Aryans" as the term for the people considered pretty.)
(Edit edit: Though that may just be a random awkward moment-in-passing. And doesn't really invalidate what I'd said before, to be sure. Just got shocked for a moment.)
