After destroying the Jedi Temple in 28 ABY, Ren used the dark side of the Force to bleed his lightsaber's kyber crystal, changing the color of its plasma blade from blue to red.
The reason his lightsaber is unstable lies in the crystal it contains. Kylo Ren's Kyber crystal cracked due to his inner turmoil. This crack mirrors the battle inside him, torn between his Skywalker legacy and his allegiance to the dark side. It's a constant reminder of the conflict that defines him.
Now consumed by the dark side, he disarms and kills his final former ally and becomes Kylo Ren. Interestingly, however, Kylo Ren 'bleeds' his original lightsaber's kyber crystal, cracking it in the process and necessitating his crossguard lightsaber.
Naturally, feeling these emotions as Ren does during the process of bleeding a kyber crystal will cause the crystal to reflect that characteristics. The result is a cracked crystal spewing malevolent power in every direction. That is, the crystal is not broken as a reflection of Ren's inner turmoil.
He obtained it by bleeding the Kyber crystal in his lightsaber that he previously used as Ben Solo. But the hilt iself, as well as the crystal, are the same, although Kylo had to add the cross-blade due to a crack in the crystal when he “bled” it.
The lightsaber's redesign was a byproduct of the bleeding process that damaged its kyber crystal, rendering it dangerously flawed and unstable, and necessitating the lateral vents were meant to prevent the cracked kyber crystal from overloading.
Many fans speculate that Kylo Ren never really learned the ability to properly construct his own lightsaber since he did not fully complete his Jedi training with his mentor Luke Skywalker. More importantly, the lightsaber uses a cracked Kyber Crystal, which is the main cause of the blade's irregular appearance.
Any kyber crystal could be bled by a Force user, including one's own, for example, if they were a former light side practitioner and kept their lightsaber. However, some Sith believed that the proper method was to take a kyber crystal from a Jedi's lightsaber and bleed it.
Answer: Yes, the Darksaber contains a Kyber crystal, which is its power source. Like all lightsabers, the Kyber crystal within the Darksaber focuses the weapon's energy on producing its blade.
The breaks in Ren's mask were meant to be a visual representation of his fractured character. Instead of hiding him as it did before, the mask tells his history, and his behavior is revealed. Tales of Villainy: Follow and Lead depicts Kylo Ren wearing his helmet between the events of Episode VIII and Episode IX.
The fate of Luke Skywalker's old lightsaber appeared to be symbolic of his philosophy; it was shattered in a Force tug-of-war between Rey and Kylo Ren. Even its Kyber Crystal was broken. And yet, in spite of that, Rey succeeded in repairing the lightsaber in Star Wars: The Rise of Skywalker.
Kylo Ren's obsession with Vader is clear, but Star Wars never explained how he acquired the helmet. It is speculated that he may have found it himself on Endor, or it could have been passed down to him by Supreme Leader Snoke.
In a galaxy filled with lightsabers of various colours, the Darksaber stands out as the rarest lightsaber colour, shrouded in mystery and steeped in history. Created by the first Mandalorian Jedi, it has passed through the hands of warriors, terrorists, and heroes, leaving an indelible mark on the Star Wars universe.
At the time of The Mandalorian story, it is pretty clear that Moff Gideon is not a Sith Lord even though he has the Darksaber in his possession nor does he have any links to the Jedi. Moff Gideon is nothing more than one of the Empire's existing bad guys who officially worked for the Imperial Security Bureau.
To be clear, Grogu is not a younger version of Yoda since "The Mandalorian" is set after "Return of the Jedi," in which Yoda (played by Frank Oz) died. They are, however, of the same species — but that species has not yet been revealed. There are more similarities between Yoda and Grogu than just looks.
A kyber crystal that had been cleansed in this manner would typically turn from red to white, and would form a powerful bond with the Force-sensitive individual who performed the ritual.
He also had a red kyber crystal that had been bled by a long-dead Sith. Dr. Cuata gave this crystal to Luke, asking him to purify it if he could. Unfortunately, Luke failed to do so, though he kept the crystal anyway.
While they may not have had romantic love for each other, they became close enough that Rey would miss him after his death. The kiss at the end of The Rise of Skywalker was a goodbye to a friend who would be dearly missed.
He was Palpatine's genetic creation, one who hadn't genuinely mastered the ways of the Sith and, thus, he was not an actual Sith Lord. Nevertheless, Kylo killing the one he believed was his master was undeniably in keeping with Sith tradition.
