Original Game Codex TextHolographic chronicles–more commonly called “holocrons”–are sophisticated data storage devices capable of cataloging vast amounts of complex information within their crystal lattice structure. Frequently used by both the Jedi and the Sith to preserve the wisdom of ancient Masters and Sith Lords, holocrons can only be accessed by Force-sensitive individuals. Some are “merely” repositories of incredible lore, while others possess virtual personalities of their own, modeled after their creators. Many believe it was actually the Sith who first developed holocron technology, as the oldest known examples are all relics of the dark side. Interestingly, Jedi holocrons take the form of a glowing cube, while Sith holocrons are usually pyramid-shaped. Some scholars claim the six-sided cube of the Jedi represents a more modern and advanced version of the original four- and five-sided pyramids favored by the Sith, though hard evidence for this idea is scarce.
