Did Kylo Ren build his crossguard lightsaber on Malachor V ? The recent re introduction of Malachor into Canon through The Force Awakens Visual Novel and by Yoda informing Ezra in the Star Wars Rebels Shroud of Darkness episode to go to Malachor. The crossguard lightsaber design is described as using an ancient design with modern components and the design dating back thousands of years to the Great Scourge of Malachor. With Ezra using a Crossguard lightsaber of his own and using a Sith Holocron found at a Sith Temple on Malachor we are left to question did Kylo Ren arrive at this same planet some years later and using the sith artifacts build his own lightsaber using the data from Revans Holocron and a cracked Kyber crystal. This further raises the question of Did Ezra create The Knights of Ren or inspire Kylo Ren in some way.
