I don't really like them, more as I'm really intrested in them.

My theory sums it up. 

Without going to far into it, I relate Jyggalag's release from bondage (look him up if you have not played the Shivering Isles DLC), to the rise of the Thalmor. They represent an ultimate order in the Tamriel, and I can sense the Daedric Prince's hand in this.
