Locke side-stepped and parried Zachary's lightsaber with his own, sending his opponent's weapon off to one side. He waited until it floated back to the other man's hand, wary of the weapon's position relative to Locke's. The Arcanist held his lightsaber down at an angle, trying to make himself seem relaxed as he answered the other man's questions.
"The Force is just a tool." Locke had been a soldier before finding the Force. He did not believe in the Force's guidance any more than he did in prophecy. "It is a fool's errand to let it lead you."
"That is where you are wrong, Consul," Zachary said. "The Force shows guidance. It is much more than a tool. The Force is a living energy."
Locke chuckled dryly, his voice turning to sarcasm. "Now you sound like a Jedi. That's just what we need in Naga Sadow. Another blind idealist."
"I'm no Jedi," Zachary growled. "Nor an idealist."
He advanced forward, angling his weapon toward Locke's head. The Arcanist parried and tried to prepare a counter attack, but before he could, the other man pivoted, and suddenly his weapon was aimed at Locke's wrist. The Consul retreated into a defensive stance, briefly glancing to one side as Zachary approached. The Arcanist flicked the fingers of his free hand, the Force - invisible to the naked eye - leaping from his fingertips to part of a fallen column. A rounded chunk of rock hurled at Zachary's head from behind as Locke parried his next strike.
Zachary must have sensed it, because he backed away, allowing the fragment of rock to fly between them. It smashed into another column, causing that one to topple into the vast canyon below the platform.
The two locked eyes, and Locke knew Zachary was trying to decide how best to attack again. The arena was silent, save for both combatants breathing. Locke decided to fill that silence before Zachary came up with a good way to attack.
"Every other Dark Jedi or Sith who shows up in Brotherhood space claims to be guided by visions. That may be good enough for Sang, it may be good enough for Tasha, but you will find that my judgement is not as easy as theirs. I don't need another potential enemy living in my Clan."
Even as he spoke the words, Locke knew they were without meaning. Everyone was a potential enemy. Sang, more or less a Jedi in hiding, could decide that Locke's methods were too cruel and seek to overthrow him. Tasha would likely support the Jedi if he did that. His Rollmaster had already attempted to seize power once, as well. Then there were the Sons and Daughters of Sadow. Each had their own plans and goals, and those often conflicted with Locke's. It was not even a surprise when it resulted in open conflict.
If visions were all Zachary had, then Locke wanted to see what he would do when they were not accepted as a convenient excuse. If he were to be a successful leader, he would have to be more creative than that.
"Surely there is more to you than some visions."
He let that statement hang in the air between them. Zachary did not attack. Locke imagined he was thinking through his options. He had gained the trust of Sang, and - apparently - Tasha. Striking down Locke, or bloodying him, might break that trust. At the same time, if he merely disengaged and left, that would definitely reduce Locke's trust in him.
"Most Dark Jedi are fools," Zachary said. "I am not here to strike at you. I was drawn here. Perhaps it is because you have so many potential enemies that I am here - to help and serve."
"Perhaps," Locke mused, "but I do not know if you are strong enough."
Locke did not wait for a reply. Instead, he attacked the other man. The Arcanist swept his lightsaber up toward Zachary's midsection, to which the Sorcerer responded with a downward parry which left Locke open to counter attack. The Consul called on the Force instinctively, quickening his movements to reposition and block his opponent's next strike. Their blades barely touched, Locke narrowly deflecting Zachary's strike away from his body. The Sorcerer was skilled, and would probably defeat Locke in a fair fight.
The Arcanist didn't intend to fight fair. However, he also did not want to injure Zachary too badly, so he had to end the fight carefully. He did intend this as a test, after all.
Filled with the Force, Locke shunted it's energy to his arms, reaching to his belt and raising his hand with a primed thermal detonator in the blink of an eye. He tossed the device at their feet and leaped backward, seeing that Zachary did the same. However, the detonator did not stay where it was. Instead, it rolled toward Locke, following his jump. He saw Zachary focused on it; feeling the Force flowing from the other man toward the detonator.
Locke didn't have time to curse before the device exploded, filling the arena between the two combatants with brilliant fire.
As soon as he saw the detonator moving closer, Locke summoned the Force again and erected another barrier, shoving it between his body and the device. The explosion buffeted the barrier, pushing Locke backward, finally shattering his defense and causing Locke to collapse back onto one of the rope bridges leading to the platform.
It didn't support him. Distantly, ears ringing, he felt the bridge falling, realizing that the explosion had detached it from the platform. The Consul grabbed onto the rope railing of the bridge and groaned as his body ached from the force of being thrown backward. He was not burned that he could tell, but had not been able to stop the kinetic strength of the explosion from causing his body injury.
Gritting his teeth, Locke held onto the Force, doing his best to ignore the pain as he climbed up the remains of the rope bridge. He finally managed to scramble onto the smaller platform it connected to and turned around, searching for Zachary.
He gasped when he saw the result of the explosion. The main arena platform was gone, either dislodged or destroyed by the explosion; the other rope bridges hanging in tatters as well. Zachary was nowhere in sight. Feeling a stab of frustration - more at the possibility the man had died than that he had apparently tried to kill Locke - the Arcanist weakly reached out with the Force. He closed his eyes and focused. His body ached. His ears ringed from the explosion. He could hear his heart pounding from exertion, but he tried to ignore it.
Finally, Locke sensed that Zachary still lived, somewhere far below. He sensed frustration, pain, and determination. Zachary did not seem that badly injured. He would definitely live and be able to escape this world on his own.
At the limit of his own energy, Locke rolled over and passed out, his last thought of how poorly that encounter had gone. It seemed his methods did not always work.
