Eschaton
The Living Book of Eschaton is the end result of Ezekial's attempt at Dion de Vermiis' Eschaton Experiment. Gathering together the Ashtani and Theran cabals, Ezekial led the group in a large occultic ceremony, binding the karma of all its members together to facilitate its gather and usage. Unfortunately, something went wrong, and both Ezekial and the experiment were lost.
Eventually, the modern day Occultists successfully enacted a ritual to retrieve both Ezekial and an unfinished Eschaton from the timestream and finished the experiment, tying their karma to that of their forebears and creating a living book in, as its name suggests, the shape of a tome that could absorb and distil karma upon those tied to it.
The Book was destroyed in the year 691 AF, when it and the Phoenix fused in order to break into the Chaos Realm in order to assault Golgotha and his horde, which resulted in Golgotha being overthrown and Glaaki being crowned as Lord of the Chaos Realm.
