This is a promontory with a strange history. It is where Vanir Tate’s non-amberite Father) originated from, the source of Bibliomancy and where the Archivist - apparently an alternate Caelin - originates from. As a single promontory, it was shattered into pieces (when it earned it’s name) and also was a target of a mind-wipe by Jean. It is halfway between Shadow known to the players and the Hamsterverse.
