Those were the four simple words that were uttered from Zeta's own lips, and they were meant for one specific man, Gash Jiren. Once a man to almost achieve Sith Lord status, but he had thrown it all away to become a Rogue Jedi, a Rogue Jedi that now called himself a Rogue Jedi Master.
It sickened Zeta. Jiren had shown so much promise, he had held great power in the palm of his own hands, now that power was gone, gone and replaced with a new found power. A power that Zeta did not believe served Jiren to his fullest capabilities.
So he set out now, on the hunt for the great Rogue Jedi Master known as Gash Jiren. His first destination, Yavin 4, if he did not find the Rogue Jedi there, he would continue to keep in search. After all, it was Gash's turn, and everyone at some point in time had their turn with Zeta, it just couldn't be avoided.
