Returning to the Temple on Coruscant, Masona accepted the rank of General within the Grand Army and also the position of adjutant of Master Windu himself. Fighting bravely in the three years of war, Jedi Masona was stationed on Coruscant when GeneralGrievous, leader of the Separatist fleet, emerged from hyperspace in the skies of Galactic City. Along with Jedi Roron Corobb, Foul Moudama, and B'ink Utrila, Masona was assigned to reinforce Master Shaak Ti and Stass Allie in locating and protecting the Supreme Chancellor. As the Republic war machine fought to protect the capital planet, Masona and his team were rushing Chancellor Palpatine into a bunker deep in the crust of Coruscant. As Master Shaak Ti fought to defend the doors to the bunker, Grievous slipped past unnoticed and engaged the four Jedi protecting Palpatine in a lightsaber duel. Grievous toyed with the Jedi for a time before decapitating Masona first. Masona's comrade, Jedi Roron Corobb accidentally kicked Masona's head across the room during the fight, causing the Jedi to become distracted enough for Grievous to kill him and the remaining two defenders.[1]
