Babel

The babels were an advanced generation of casts created in the Catherion Imprimature to overcome the limitations of casts. The goal was to make a self-aware system that would be linked to the mind of a time-active agent instead of the the Homeworld's noosphere or the operating system of a timeship.

Only about eight were created, and all were incurably insane. One escaped babel massacred almost everyone at House Catherion, leaving only one survivor; (PROSE: The Book of the War) the Order of the Weal subsequently kept it prisoner under House Ixion, where Chatelaine Thessalia consulted with it about the upcoming War. (PROSE: Newtons Sleep)

Most of the other babels were confined in areas where they were deprived of radiation and eventually starved to death. However, at least three were allowed to survive and were used in the Lethean Campaign during the War. (PROSE: The Book of the War)
