Holocron

Holocron is a device that is used to store information and is widely used in the Jedi Order, but it is not unknown of its usage by the Sith. These valuable objects where destroyed during Order 66. One holocron was obtained during the Battle of Geonosis when a Geonosian dropped it when it was killed. During Operation: Knightfall, one was found in the comm room and the other was carried by a Jedi Master before he was killed by the clones.

Trivia

 * The holocron used in Battlefront is based on the Jedi's Great Holocron.
