Oof, Sung won't be happy at that, I hope that, seeing there's no beheading, the healer 's able to heal herself and them, it's also more plausible seeing as he didn't just kill the 2 strongest to begin with (but I get that getting cut in half is not easily survivable).
Then was The Architect working on making a vessel for The Monarch but after Sung's victory decided to change sides or something like that? Also the "they" are the other Devas? (no need to answer with spoilers, just aloud speculation, but thanks for the interest) And finally, doesn't Emperor sound better? Sure it's more exploited but is precisely because is a higher rank and sound more imposing.
