Once Luke Skywalker lost his father's lightsaber, he made his own at Benkenovi's hiding place in his hometown. I referred to the book of Jedi left by Ben. The content was full of amazing mystery. According to that, I used Benkenobi's design as a base, but I do not have the essential Kyber Crystal. So we use a furnace to train multiple crystals. Although it was difficult, it succeeded brilliantly. As expected, there is only anakin's blood flowing. Its workmanship was highly praised by Vader. And also to Lord Sidius.
Luke who overcame Sith's lineage at Enda rebuilds the Jedi Knights. As promised to Yoda
and Obiwan. However, there was a problem in taking multiple disciples. It was hard for him to make his own lightsaber at the same time at the beginning of training. It is because difficulty of experiences experienced and that there are not many crystals beforehand and can not be trained. Luke felt a little, but I regret that I should have kept the Jedi's rule that he should not have more than one disciple at the same time. As a result, the disciple 's lightsaber was disappointing. I could not teach the structure by rounding my own lightsaber. Because it is only one. I sincerely want one book I lost in the first fight with Vader. It was Han and Leia 's son Ben that best supported it among his disciples.
Ben who wanted to be stronger than other disciples lost the temptation of Snoke and killed themselves. In order to carry out that betrayal, a stronger lightsaber was indispensable. So I dyed the crystal red and made a cross weapon. After that, I will continue to use my grandfather's lightsaber until I get it, but the degree of completion is low and I have trouble. Because there is only one crystal and it is not stable.
I believed that someone kept my grandfather 's weapons.
Luke felt his weapon was the last lightsaber based on Jedi's knowledge.
But one day a woman named Ray comes to hand my grandfather's lightsaber. Luke is relieved that his grandfather's weapon did not pass to Cairolene. And I will bet the expectation as a Jedi in Ray who has a lightsaber in the Force.
It is the beginning of the one-on-one principle of the Jedi. If either Luke or Ray dies, it gives the lightsaber used for the new disciple. There are only two people to know about this phenomenon. It is the adoption of the secret principle of the Jedi Knights. Luke declared dead secretly they collusion, training and skilling the skills of snake heart. There is nothing to suffer from the production of the lightsaber any longer.
