The whole Quincy timeline is really doing my head in these days. What is there deal? They're humans with a particular power set, but some of them have to be 1000 years old (Bazz and Jugram for example), yet Souken apparently left "decades ago" (assuming MS is correct), but at the same time there were other Quincy bloodlines in the world of the living (hence Masaki).

On a side note, I wonder if Ywach specifically avoided taking the power of any of the Kurosaki children with his Auswählen, as they could all have had the potential to meet the specifics for what Ichigo turned out to be.
