Bail Organa's data holocron was a data holocron that was made by the former senator from Alderaan, Bail Organa, to store the locations for new bases for the Rebel Alliance, should they ever lose their base on Yavin 4. The data holocron was encased in phrik, one of the strongest substances in the galaxy. When the first Death Star destroyed Alderaan, the data holocron was able to survive the superlaser's blast. Shortly after the Evacuation of Yavin, both the Rebel Alliance and the Galactic Empire discovered that the holocron was floating somewhere in the Graveyard.
