In the year 19 BBY, concurrent with the execution of Order 66, Ekim Ryelli, a Jedi Master, engaged in a fierce lightsaber battle on Nicht Ka. His opponent was Telloti Cillmam'n, a Jedi from the ExplorCorps, who had undergone corruption due to the influence of Warb Null's armor. Ultimately, Cillmam'n prevailed in the intense conflict, decapitating Ryelli.
