Holocron number one.  These recordings are an attempt to preserve the history of the galaxy despite the Empire and New Republic's attempts to re-write it.  This particular recording is the recounting of our history from the point of the Big Bang, roughly thirteen billion years before the battle of Yavin; up until the end of the Zhell-Taung war on Coruscant that caused the Taung to flee off world, and established the human dominated culture on Coruscant.
