Maybe Adonalsioum will turn out to be the book reader. I always think back to the old shoemaker story. One becomes many to experience and understand more. Cosmere is a story being told by tons of POVs, the reader experiences each of these POVs and slowly over time the shards or books (stories) will be combined, or rejoined when the reader has finished the entire collection and has shared all of the experiences. Maybe Sanderson is Hoid himself helping nudge the reader in the right direction along the way.
