Oshu Wei

Strong willed and even stronger physically, Jedi Master Oshu Wei was a Besalisk Jedi Master who was realized to be force sensitive at a very young age. After many years of training under his master, Jedi Master La Breakhid, as well as honing in his technique with his lightsaber fighting ability (which was necessary in the time of war between the Jedi and Sith), Master Wei even mastered Juyo. Devoting himself to the Jedi for his entire life, a younger but still wise Oshu Wei went to the crystal caves of Ilum and spent almost six months meditating due to his inner conflict regarding his use of both the light and dark side. After this long period of meditation, Oshu formed a new kind of crystal out of his previously blue one. When using his darker nature to create this crystal, it bled slightly creating the first purple kyber crystal. He used this crystal in his double bladed lightclub, built from trees and parts on Kashyyyk, as Oshu was very close with the wookies.

In the year 657 BBY, Oshu took part in the Siege of Pii VII along with several other Jedi. The Siege of Pii VII resulted in the destruction of Darth Jadonus' Factory as well as the revelation that the evil Sith Lord Darth Jadonus was in reality Oshu Wei's old master who had abandoned the Jedi Order, La Breakhid. The siege ended with the deaths of Oshu Wei, Darth Jadonus and Jedi Sentinel Boosa Karpgoss.
