I would think the Old guy Quincy is Stern Ritter G, "The Gun" and Stern Ritter C is the guy with the staff "The Control/er" or something? Seems like that guy who attacked the 12th div. But i think that may have been Shaz Domino. I also think that Letter, does not indicate strength, just merely an epithet.

Anyway, I'm 100% sure Yhwach has an equivalent to the Royal Guard.

P.S. Heres my theory to the "last quincy alive" thing. Where do Quincy go when they die? Doesn't seem like SS. Maybe they have their own place and are merely Quincy souls, with Quincy powers, which would also explain why that Uryu was treated so special. But then again, Yhwach made "the selection" maybe he just left those who have the strongest Quincy powers with them for the war effort, maybe they are all impure and Uryu has the purest blood?
