Anger seethed within Locke. He prepared himself as the Massassi warriors approached. How dare Cethgus continue to deny his superiority and question his actions? The first warrior attacked, and Locke ducked inside his defenses, slicing his lightsaber across the creature's midriff. The warrior howled, and was replaced with another, who snarled at Locke in a deep, alien voice. Having no room to maneuver, the Arcanist plunged his lightsaber into the second warrior's chest, bringing them eye to eye as the weapon sank deeper. Locke growled right back at him, vocally expending his frustration.
Locke yanked his lightsaber out of the warrior's body and retreated a few feet, forcing himself to consider the situation. The death of two of their warriors had caused the Massassi to think twice. Now they hesitated, considering their prey. That gave Locke an opportunity to process the situation. He would not let Cethgus goad him into this madness. The Consul knew he had already made a mistake by rushing to attack Cethgus. The Proconsul was just so blind and stubborn.
He was angry that Cethgus had brought the engagement to this, but silently acknowledged the Zabrak's cunning in battle. He was an excellent warrior, but he did not seem to be much else. He could fight, but could he lead? Locke would show him what was truly required. The Arcanist gathered the Force and prepared himself, feeling the energy well up in him. It seemed to pass through his body, rising like a fountain, finally settling around Locke's lungs and throat.
When Locke spoke, his voice was like thunder.
"Stop!" he shouted. The Massassi paused at the sudden boom of the Arcanist's command, seeming to listen. If they understood Cethgus, that meant they understood Basic. Locke turned his gaze to their chief. "My opponent is a coward! He seeks to use you to fight his own battles, as no true warrior would. He retreats, and allows you to die in his place."
Confidence building, Locke exerted his will. He stood straighter; he made his tone commanding. It was not without cost, as his body ached. Even with the Force, he could feel the pain of forcing his lungs and throat to such extremes. This would have to end quickly.
"You have seen that I can fight your warriors. Now stand aside and allow me to conclude my duel with the one who would have you do his work for him!"
Locke's eyes met the Chief's. For a moment no words were spoken and the Bakuran wondered if he had made a mistake.
Then Cethgus broke the silence. "Don't be fools! He killed one of your number."
"Indeed," Locke replied, voice quieting to normal levels. He did not look at Cethgus. Instead, the Consul kept his eyes locked on the Chief's. He let go of his lightsaber, letting it roll to the side to indicate that he did not mean to attack the warriors further. "But only as a byproduct of honorable combat." He extended his arm, pointing in Cethgus' direction. The Zabrak was almost entirely obscured behind the ranks of hulking Massassi. "Unlike him, I did not hide behind rows of warriors and attempt to have them fight my battle for me."
The Chief seemed to consider for a moment. Then, as Cethgus began to speak again, the Chief shouted something in his own language. The rows of warriors stepped apart, forming a ring as they had before. This time, it was much larger. Cethgus stood at the opposite side. His face contorted in a snarl as he glared at Locke.
"Very clever," the Marauder growled.
Locke merely nodded. He lowered a hand to his belt, very aware of how vulnerable he was without his weapon. A plan formed in his mind as he continued to speak. "You see what true leadership is? Now, don't hide again. It is so uncharacteristic of you. Besides, you have always been one to tackle your problems head on, or are you truly even less of a man than I thought you were, Zabrak?"
That insult set him off. Cethgus roared with anger and charged toward Locke. Though the distance was longer than it had been at the start of the battle, the Marauder closed it quickly, likely using the Force to enhance his speed. Frustration quickly rose within Locke. Though he had expected as much and sought it, the Arcanist was still disappointed. If words would not work with Cethgus, Locke would show the man a different kind of language. The Bakuran grabbed one of the detonators at his belt and tossed it toward his opponent along the ground, at the same preparing the Force. He poured his anger into his other hand, letting the violent energy gather there.
Reacting quickly, Cethgus leaped as soon as the detonator left Locke's hand. It exploded below him, the shock wave battering the Marauder from below. While he was distracted, Locke raised his other hand and unleashed all of his passionate anger in one, concentrated strike. Lightning leaped from his fingers again. The bolts arced and struck Cethgus at almost point blank. The man growled, the force of his momentum carrying him on behind Locke. The Arcanist turned and watched as Cethgus hit the ground and rolled several feet, his lightsabers each rolling away in a different direction.
Locke breathed deeply. He wanted to lecture Cethgus more. He wanted to remind the Marauder of his foolishness. He wanted to put the other man in his place. Cethgus' plans would result in obliteration for not only Naga Sadow, but the Brotherhood as a whole. That could not be allowed. Locke knew he had to quickly subdue Cethgus. Otherwise, the Marauder would get up and likely not let his anger get the best of him again.
Running forward and calling on the Force once more, Locke slipped his SH-9 slugthrower into his dominant hand. With the other, he gestured toward one of the dead Massassi warriors. Tendrils of the Force wrapped around the creature's fallen weapon. Locke yanked at it and motioned his hand in a throwing motion, the weapon flying forward. It hit Cethgus in the face as he attempted to raise his head, seeming to stun him for a moment.
Next, Locke focused the Force around the Zabrak, closing his free hand to a fist, imagining that he held Cethgus' throat in it. He knew he could not truly hold his weakened opponent this way, but it had to be enough. At the same time, he raised the slugthrower and aimed it at Cethgus' left leg. The Marauder barely noticed, hands in fists, all willpower focused on fending off Locke's Force attack. His motionless lower half was an easy target.
There was a sharp, loud crack as Locke pulled the SH-9's trigger. Cethgus howled as the slug went through his kneecap, though Locke could not say if that was in pain or anger. The Arcanist finally stopped beside Cethgus, calmly repositioning the slugthrower. He fired again, this time sending a slug through the Zabrak's' other knee cap. Locke was panting now. Sweat beaded on his forehead, running into his eyes. His throat ached. His mind throbbed with a severe headache. This day had taxed him in more ways than one. He looked into Cethgus' sunken, emerald eyes. They glared back, seemingly filled with rage.
When Locke spoke, it was in a quiet, hoarse whisper. "Your plans would doom the Brotherhood. You lack foresight. You would conquer? You would reveal us to the Jedi and the Alliance, and we would die. You cannot lead!"
As Locke spoke, Cethgus raised shaking hands to his shirt. Locke watched, preparing for any counter attack, but the Zabrak merely grabbed his own shirt. Then he ripped it open.
Locke lost his concentration as he saw what was there, branded anew into the Marauder's chest. That distinct shape - with a crescent below and spikes along the outer edge - was recognizable across the Brotherhood. Locke was distantly aware of Cethgus repositioning his hands, but something else was at the forefront of the Consul's mind.
That is the Arconan emblem!
He heard Cethgus speak, then. It was a quiet whisper, like a blade unsheathing in shadow.
"Arcona Invicta!"
Barely detecting the Force strike in time, Locke turned away as quickly as he could. It hit the back of his shoulder, causing an unnatural snapping sound. The Arcanist stumbled forward, falling to his knees, crying out as his right arm exploded in pain. Locke dropped the slugthrower and clutched his broken shoulder with the opposite hand. He dimly recognized the agony of broken bones. Locke grit his teeth and focused the Force to numb the pain. Unable to do so fully, he instead turned to his emotions and focused on them. Shaking, the Arcanist stood up. He removed his S-5 blaster pistol from its sheath and pointed it at Cethgus with a trembling hand.
"Why?" He mouthed. He moved his tongue, gathering moisture to speak. "Why go back now? Traitor."
Cethgus chuckled then, though it ended in a wheez. "You fool, so idealistic. I have never been loyal to you. The Shadow Clan has given me everything. Why would I turn my back on them?"
Hearing those words caused fury to blossom within Locke, but he did not have the will to express it. Instead, he turned to the Massassi War Chief, who still watched the battle. Locke approached him slowly, doing his best not to stumble. The weight of responsibility seemed to crush the Consul's shoulders. He had a lot of work to do.
"Keep him," Locke said. "Do not let him leave."
Then he turned back to Cethgus, one more thing to say. The fury was still there in the Consul's mind, but other thoughts overtook it. The shock of such betrayal had not fully hit him yet. They all had trusted Cethgus. The Dark Council in appointing him, Locke, the Summit, the Clan. I should have known better.
Locke spoke to his - former - Proconsul one more time. "I will inform the Taldryan Summit that they can do with you what they will. I believe they have a notable distaste for Arconans. Perhaps they will send you back to Arcona, perhaps not. I am done here."
Turning away, Locke recovered his weapons and left, mind focused on the future.
The background info here is good. It's nice for the reader not to have to do extra research on the current events going on in your clan to understand the context of the battle.
Repeating the word "entire" 3 times in two sentences reads a little awkwardly.
