2021 has been a busy year for the wider Star Wars: The Bad Batch season 1 released on the Disney+ streaming service, Lucasfilm launched a massive transmedia initiative set 200 years before Star Wars: Episode I - The Phantom Menace, and there have been a slew of other novels and audiobooks as well.

Star Wars has always been a transmedia universe; the first tie-in novel was published in 1978, and Lucasfilm's first attempt at a single narrative spanning multiple mediums was in 1996's Shadows of the Empire. But Disney took things one step further when they acquired Lucasfilm in 2012, branding the old Expanded Universes non-canon (or "Legends"), and introducing a new rule of canon. In the past, Star Wars had taken a tiered approach in which the films were absolute canon and tie-ins were expected to adjust to anything he did. In the Disney era, though, everything is equally canon, loosely coordinated by the Lucasfilm Story Group. It means anything can change the lore - including the books and comics.

In fact, in the Disney era Lucasfilm has used tie-ins to explore the wider canon, resolving continuity details and fixing background issues. Major changes in lore have taken place far from the big screen, only noticed by fans who follow other mediums, and that's been especially the case in 2021 - a year where Lucasfilm attempted to clarify the relationship between the sequel trilogy and the broader film franchise.

Star Wars' New Force Powers In The High Republic Books

Star Wars Hyperspace Lightspeed

The Star Wars: The High Republic books and comics have introduced a range of new Force powers. They include:

  • The Jedi Meld, in which a number of Jedi bind their power in the Force together to accomplish feats that would be beyond a single Jedi.
  • Hyperspace tripping, a difficult-to-control ability to experience visions of distant worlds while traveling through hyperspace.
  • A Force power called pathfinding, unique to a Force-sensitive species called the Talortai. They possess an innate sense of direction, allowing them to navigate the cosmos with ease.
  • Some Force sensitives apparently possess an intuitive connection to machines, presumably an ability demonstrated by the young Anakin Skywalker when he built C-3PO.
  • An ability conceptually similar to the famous Jedi Mind Trick, where Jedi who possess empathic talents can "soothe" the emotions of others. High-profile Jedi feared this power was a little too near to the dark side, as it is inherently manipulative.

Lightsabers Possess A New Weakness - One The Sith Would Never Use

Yoda With Lightsaber in Attack of the Clones

Cavan Scott's novel The Rising Storm reveals lightsabers possess a weakness the Sith have never taken advantage of - because it would also weaken them in any combat with a Jedi. Radiation emitted from a recainium reactor disrupt any energy weapon - from a humble blaster to the legendary weapon of the Jedi and Sith. A prototype reactor was developed during the High Republic Era, although the secret appears to have been forgotten.

The Ancient Origins Of The Sith Have Been Confirmed

Star Wars Rise of Skywalker Palpatine on Exegol

Lucasfilm's book Secrets of the Sith purports to be a collection of the Emperor's notes on the Sith, and it confirms the ancient history of the Sith. It reads:

"Legend has it the Jedi Order suffered a deep schism millennia ago. An opposing sect dedicated to the glory of the dark side arose from the ashes. The Sith did not share the Jedi's myopic view of the Force. They embraced the dark side as a means to personal gain and ultimate victory. And, for a time, that great victory would be achieved. The Sith Order grew, spreading its might across the galaxy. But the Jedi became jealous. They would not tolerate a challenge to their authority. After thousands of years of war, the Sith were pushed to the edge of extinction. From the darkness, those who survived laid the foundations for our Order's return... and my rise to power."

Order 66 Wasn't The First Jedi Purge

Palpatine tells Commander Cody to execute Order 66 in Star Wars Revenge of the Sith

Star Wars has revealed Order 66 wasn't the first Jedi Purge. Lucasfilm's Star Wars: The High Republic transmedia initiative is set some 200 years before the events of Star Wars: Episode I - The Phantom Menace, at a time when the Jedi Order was at its height. During the book, the of the Jedi Council discuss whether or not the Jedi should serve as a military force on behalf of the Republic, and the debate turns to ancient history. "There have been times in our history when the Order was reduced to but a handful of ," Jedi Master Yarael Poof observes just after a mention of the Great Sith Wars. This suggests that, as in the old Expanded Universe, the history of the galaxy became an unceasing war between light and dark, and at times the dark came close to destroying the light - making Palpatine's achievements far less remarkable.

Star Wars Has Revealed The Truth Of The Rule Of Two

Building upon retcons from the Star Wars: The Rise of Skywalker Visual DictionarySecrets of the Sith cements the relationship between the Sith Rule of Two and the Force Dyad, which features so prominently in the sequel trilogy. It seems the Rule of Two was in part established in an attempt to create the Dyad, with the Sith failing to realize it required both dark and light. In truth, Star Wars: The Rise of Skywalker rather confused the issue with the Rule of Two, introducing the Sith Eternal, and Lucasfilm has been struggling to figure out how to tie that particular cult in with the Rule of Two.

Star Wars Reveals Secrets Of Darth Plagueis & The Force Dyad

Lucasfilm's book Secrets of the Sith gave a first glimpse of Palpatine's legendary master, Darth Plagueis. It seems the Emperor wasn't lying about Darth Plagueis' ability to keep someone else from death, although he had not yet worked out how to apply this extraordinary power to himself. Presumably Darth Sidious chose to kill his master before he could further refine his skills, and continued to develop them himself over the decades. Curiously, Lucasfilm's Secrets of the Sith takes a different approach to Darth Sidious to the Expanded Universe, revealing Darth Plagueis was killed while Palpatine was just a senator - potentially long before the events of Star Wars: Episode I - The Phantom Menace.

Secrets of the Sith suggests Star Wars - and all Palpatine's greatest secrets were built on the knowledge his master ed on. Darth Plagueis was even obsessed with the legend of the Force Dyad, and he attempted to forge a Dyad with his apprentice. "Though he was wise in the ways of the Force, he proved unworthy of the task," Palpatine reflected. "I, too, attempted to facilitate such a connection with my apprentice Anakin Skywalker. Yet even with the so-called Chosen One at my side, the balance we shared pulled against the perfection of the dyad." This further hints at another potential retcon; that Palpatine was actually interested in Anakin Skywalker because he thought he could use the boy to create a Force Dyad, just as his master had dreamed.

The Reason Anakin Skywalker Built C-3PO

Star Wars has revealed why Anakin Skywalker built C-3PO. Kristin Baver's Skywalker: A Family At War is Lucasfilm's official biography of the Skywalker family, and it reveals the droid was the manifestation of all Anakin's childish hopes and dreams.

"The boy longed for a life far from Tatooine, free to explore the galaxy and fulfill his dreams of becoming something far greater than a Toydarian's property. The droid he constructed was capable of millions of forms of communication. Anakin dreamed that, one day, with C-3PO as his faithful traveling companion, he and his mother would be able to venture anywhere in the galaxy and be understood and be able to understand the natives, whatever their language."

Star Wars: The Bad Batch Revealed The True Nature Of Order 66

Spinning out of the events of Star Wars: The Clone Wars and Star Wars: Episode III - Revenge of the SithStar Wars: The Bad Batch explored the nature of Order 66 in remarkable detail. It revealed Order 66 wasn't just a command; it activated inhibitor chips that rewrote the clones' entire personalities, ensuring they were completely loyal to the Empire - and to Emperor Palpatine in particular. Even more disturbingly, when Wrecker's inhibitor chip was briefly activated his own consciousness remained aware, active but suppressed, suggesting the clones essentially became slaves. Some clones resisted Order 66, and the effect faded over time.

Why Palpatine Really Sent Darth Vader To Mustafar

Star-Wars-Biomes-Mustafar

Lucasfilm has fleshed out the dark history of Mustafar, the volcanic world Palpatine sent Darth Vader to in Star Wars: Episode III - Revenge of the Sith - and where the Emperor encouraged his apprentice to make his home. The planet is a vergence in the Force, the site of a dark side ritual that attempted to conquer death itself. According to Lucasfilm's book Secrets of the Sith, the Emperor was aware of Mustafar's dark history, and hoped Darth Vader could learn more about it through his meditations on Mustafar. "The cost of activating the Aeon Engine was steep, draining the life energies from Mustafar and those who dwelled there," Darth Sidious reflects. "But to obtain true dominion over death, any price is worth paying... If such a device could be re-created, it would undoubtedly prove useful in the hands of the Sith."

How Kanan Jarrus Survived Order 66

The opening scenes of Star Wars: The Bad Batch episode 1 retconned how Jedi Padawan Caleb Dume - destined to become Kanan Jarrus, hero of Star Wars Rebels - survived Order 66. This tale had previously been told in an official tie-in comic, but Star Wars: The Bad Batch told a different version of the tale, in which the clones turned on Caleb and his master Depa Billaba while they were conducting a mission rather than when they were relaxing around a campfire. It further wrote the Bad Batch into the story, because their inhibitor chips didn't activate (at least not right away for some of them), and so they helped Caleb escape.
