Ah I haven't posted in a while but just had too after I noticed something huge/ have a crazy theory.

Remember that place with the giant quincy symbol in Hueco Mundo a few chapters ago and when Ichigo and Co first broke into Los Noches and said there was an older building/s under Aizens/the hollows building. Might be a bit insane but what if Hueco Mundo was originally the Quincy World and after the war the Soul King decided to punish the quincy/yhwach by making the place lifeless, Releasing the hollows there (anti-quincies) and making it eternal night (Yhwach is weak at night so presumably he wouldn't be able to return to his home world). Would explain the deep hate that he had for the Soul King and the hate that the Quincies had for the Shinigami.

now to go and read the next chapter...
