Ser Olmy is concerned by the prospects of the Way being re-opened with the attendant consequences, and by the revelation to him by an old friend that one of the deepest secrets of the Hexamon was a captured Jart whose body died in the process but whose mind was uploaded. Its mentality was alien and powerful enough that it took over or killed many of the researchers who attempted to connect to and study it, so it was hidden away deep in the Stone. As he studies the Jart, Olmy comes to believe that the Jart allowed itself to be captured and is a Trojan Horse. The Jart reveals tidbits about the Jart civilization: in essence, they are a hierarchical meta-civilization that ruthlessly modifies itself, attempting to absorb all useful intelligences and ways of thinking that it encounters, in the service of the Jarts' ultimate goal - to transmit all the data they can possibly gather to "descendant command". Olmy investigates further and discovers that descendant command is the Jart name for what they know as the "Final Mind" - a Teilhardian (or Tiplerian) conception of an ultimate intelligence which will be created at the end of the universe when all intelligences merge themselves into a single transcendent intellect which will effectively be a god. Olmy underestimates the Jart, and it begins to slowly take over his body and mind. Its original mission, assigned to it hundreds of years ago was to engage in sabotage and transmit its freshly acquired understanding of humanity back to present command, but the return of Pavel Mirsky changes everything.
