The Ghost Bloods and the Enlightened Spren

I don't fully understand what they are wanting, wat jaanat or the enlightened spren, other than gaining power in a way that is maybe less restrictive then the regular radiant powers. Yet her ability to connect in the large way that she did before the desolation, i think could be a point of interest for the ghost bloods. That one is the one that makes the most sense to me. Maybe that's heavy speculation, doesn't mean anything at all. Let's stay focused on theghost bloods because they do have a shown and demonstrated hierarchy and structure.
