I hate to say this, but you are entirely wrong in your logic behind the Oghma Infinium. If you would have truly listened to was Septimus said, he originally believed that the Heart of Lorkhan was hidden away in that puzzle box right before their disappearance. So he never even spoke about the OI, seeing as in how he thought something else entirely was locked away within. So please get your facts straight before chastising another. In any case, the cube was indeed used by the Dwemer last. Septimus was the first to find and study it after the Dwemers' disappearance, and this is reinforced by the fact that Dwemer blood is needed to open it.
