Sci is an Artificial Intelligence, which in the future, is an extremely broad term. He refers to himself as a Realized Consciousness to distinguish himself from more automated constructs that inhabit Aeternae Aetatis.
The Novel is an autobiography transmitted from a future time frame, circa 22nd century. It has been translated and editted as near as possible to the spirit of the original language, although the evolution of language has made this task difficult.
Because this autobiography was transmitted from the future, the events that occur within should be considered fictional, as the temporal causality necessitates the erasure of the timeline from whence it came.
Sci, however, indicates that it may be possible that a loop paradox will occur, whereby The Novel creates the identical circumstances that he wishes to avoid. He hopes, some how, that if we cannot avoid the shape of the future he observed, then perhaps we can avoid the path it takes.
