A plausible and well-thought-out theory. But if I may ask something, when and where was it ever mentioned that Karu was a bishop's apprentice? If I recall correctly, he and Landkarte spent a lot of time in the Book of Hades when they were children, then infiltrated the Barsburg army in their adult years, but I don't remember coming across any mention of either of them being a bishop apprentice.
