The Blackthorne Family Holocron was created at a presently-unknown time by an unknown member of the Blackthorne Family. It was known to have the history and teachings of the family chronicled within its store of information. Its time of creation and who created it was unknown, as the holocron itself was lost at some point before the Clone Wars. Neither Faarel Blackthorne, nor his father, had access to the device, though it was speculated that Kladaar Blackthorne once had access to the holocron and, possibly, was the one responsible for its loss.
