Mission to Kashyyyk (Galactic Sith War)

The Battle of Kashyyyk was an attack led by Darth Vader to hunt down another one of the surviving Jedi, Kento Nion.

The Invasion
Darth Vader found another surviving Jedi, who was named Kento, and led an attack on the wookiee homeworld of Kashyyyk. There, the dark lord killed a lot of wookiees that were hiding Kento. Vader found Kento, and they engaged in a lightsaber duel.

The Boy who will become Vader's Secret Apprentice
Near the climax of their duel, Vader kept on injuring Kento with his force choking powers. As Vader was about to finish off Kento, Vader's lightsaber was force pulled out of his hand by Kento's son, Jacob Nion. After Vader killed Kento, he gazed at the kid, realizing how powerful Jacob is. Then a group of imperials ran in and prepared to kill the boy, but Vader killed the imperials and saved Jacob's life. Thus, Jaocb became Vader's secret apprentice and was given the code name Starkiller. Jacob's Sith training would last sixteen years.
