Parables' Retaliation

In a world forged by the will of gods and man, determining what comes next is often the question as the forefront of individuals' minds. It's near impossible to foresee what comes next. An entire vein of magic dedicated to the art and craft of collecting information can only nip at the edge of divining the future. Arcane magic tends to fall short in that way. 
But there are other sources of magic in this world, and other types of incantations, or even beings, that can foretell the future. Though it is not foolproof. No, the thing many people don't understand about diving the future is that it is the furthest thing from set in stone. Any creature pushing through the veil and peering into what is to come merely perceives one possible outcome. There is no way to ensure that will come to pass, only a path that is present. 
Well, almost no way. Hags are a different breed of creature. By its very nature, their magic is unknowable to practitioners, divine or arcanely based. What forces their magic pulls on is completely unknown, even the Fey Courts grasp at straws when pushed for an explanation of how the Hags operate. That is why it is all the more troubling when a Hag, be it a mother Hag or a coven, predict something. 
The Coven of Concealed Sisters' voices rang through the air, shaking and trembling the nearby wooden and stone buildings. Their prediction was spoken with the type of viscous accuracy that stings the ears when heard, that makes the listener recoil in their shoes. Truth, cold hard and dead, leaves the sisters' lips. Speaking in unison, they utter the words, the "Parable's Retaliation."
They roar with conviction about the betrayal. The betrayal of a collection, towards its keepers. And the betrayal of those keepers, on the world. The Book, coming apart at the seams, and the pages falling into obscurity, weathered and ruined. 
They speak of the binds breaking, the bonds shattered, and the shackles loosening on the black cliffs of the North, at the Chained Library.
