They take more of us in every day, regardless of whether we still have flesh or not. The Soul Shriven, as they call them, are the bulk of those taken in; people whose bodies are long since wasted away, but whose spirits live on in Oblivion. Some of them say their souls are inside gems, and that they can feel themselves being jostled about as their respective gems are moved from one place to another. They are filled with so much sorrow it crushes the heart just to hear them speak of the lives they have mostly forgotten.
