Biodata

The substance common to all conscious entities which defines an individual's place in space-time and dictates the relationship between that individual and the rest of history. Describing biodata is difficult, as a full understanding seems to require an inherent grasp of time-active modeling only native to the Time Lords-- perhaps the best simple definition is "Time DNA".

In the same way that DNA shapes an individual's genetic form, biodata shapes an individual's course through the continuum, and can be regarded as a strand of information running through all four mundane dimensions: the shape of the biodata strand, as the individual moves along his or her own timeline, is the true shape of that individual's life.

Biodata evolves; the Biodata of higher species (conceptuals, gods, Time Lords etc) able to influence the biodata of lesser species.

If one knows how to read an individual's biodata strand, one can read that individual's entire history from every facet of his or her past to every moment of his or her future. The Time Lords, Faction Paradox, the Celestis and the Sisterhood of Karn do know how to read biodata, but the procedure is difficult (and for the first three groups anyway) requires extensive use of technology.

It is far easier to read past biodata than future biodata, making future prediction based on it an inexact science erroring out to greater degrees the further ahead one looks.

A Time Lord's biodata changes with each regeneration, the new regeneration and its potential being added on to all prior points of the Time Lord's biodata each time.
