This is equal parts "makes sense", "at least", and "yeeesh".
But then I go back and forth about whether I even really want a "known" Thirteen, or just perennially and persistently rumored but never found ones. I do know I prefer the idea of a plurality of beliefs akin to what we have; it seems more interesting than "validating" one set and making them characters.
I enjoyed the idea at the time of the Guiding Hand and Thirteen somehow coexisting in IDW lore, until they wound up validating one and Shockwave-ing the other, bringing us kind of back where we started.
