Okay, after playing Tsukihime (still need to do Kohaku), KT, F/SN, and starting KnK, I have no clue who the hell Zeltrech is supposed to be. Same with Altrouge and Miyako. I know who they essentially are, but that's it. Where does everyone get all this information? Where can I find it? Did I just miss something entirely and I'm just a retard?
