Holocron/Legends

"The holocron is overflowing with advice! Listen and look..."

- Bodo Baas

A holocron was a crystal lattice (often cubical and sized to be held in one hand) in which the Jedi, as well as the Sith, of old stored phenomenal quantities of data, as well as the holocron's gatekeeper. The Sith also had their own form of holocron technology, and they seem to predate the Jedi in using the technology by three thousand years.

Description
Sith holocrons usually took the form of a pyramid, and the existence of the first Sith holocron predates that of a Jedi holocron by at least three thousand years. The technology to create the pyramidal holocrons common to the Sith was something gifted to the ancient Sith king Adas by Rakata warriors trying to gain his trust. He accepted their technology and made a holocron, but he saw through their ploy and rebelled against them. It can only be assumed that the Jedi also learned the secrets of the holocron by Rakatan example, possibly by studying mysterious artifacts left behind by the Infinite Empire.



The holocron was able to capture the appearance and cognitive networks of the holocron's owner, and transform this into a three-dimensional hologram. This gatekeeper acted as a guide through the holocron's store of information, as a search and recovery engine with a more personal touch. These gatekeepers could relate stories from the holocron's archives to events in the life of the one who activated the holocron. Jedi gatekeepers could sense the ability and level of a Jedi, and offer or restrict information accordingly — so that Padawans were not shown information too advanced and dangerous for their basic stage. However, Sith holocrons usually allowed the activator unlimited access to its entire dark side repository.

The technology to make them was nearly lost after the Great Jedi Purge. Surviving holocrons contained information including Jedi techniques, blueprints of ancient starships, and historical information about the universe; as a result, they were quite valuable. Usually, only Force-sensitive users could access a holocron, though it is known that Bastila Shan's father also made one, which he used as a journal.

Although not seen in the film, during production of Attack of the Clones, the film's propmakers made three holocrons for its Visual Dictionary: a Jedi holocron, a Sith holocron and the Great Holocron.
