The Knight leapt toward his wizened foe with a snarl, his free left hand lashing out to throw a wrecking ball of telekinetic energy forward. Liam smoothly rolled aside, his own left hand extending two fingers as it gripped his emerald blade; a slab of stone tore itself from the ground, before spinning toward the Equite. Turel met it in midair with a powerful slash, his saber cleaving the rock apart, his scarred face a caricature of the Dark Side as its contours were lit by the glow of molten stone. His blade came down fierce, bouncing off of Liam's blue sword before flowing smoothly into a vicious kata.
The older man met each assault smoothly with a flashing series of his own attacks, every strike lasting but a fraction of a second as the pair danced back and forth across the cave wall. Liam launched a series of vicious strikes for his opponent's extremities, trying to take his foe apart before launching a spinning kick. Sorenn smoothly ducked the attack before spinning up with his own strike, the powdery glow of his blade biting into the edges of Torun's thick beard before being knocked away. A blast of lightning flashed out from his palm toward the Consular's face, only to be caught upon the crossed lengths of two lightsabers and answered with a mighty telekinetic push.
This time, Turel was ready for it, leaping high above the crushing wave to land behind his former Quaestor. His blade came down hard, and Liam's twisting defense only barely caught it above his shoulder. A grunt of effort escaped the man's mouth. "You're getting slow, old man." He snarled, the Dark Side coursing through his veins.
A powerful kick to the lower back sent the Jedi rolling with a groan, sprawling on the ground as his sabers flew wide. Rolling aside, the old man barely dodged a leaping slash from the Knight, the blade of the younger man's lightsaber shredding stone with a high-pitched shriek. The Dark Guardian roared as his hands came forward, his lightsaber falling aside, discarded. The Dark Side poured through his arms like a tidal wave, bending his fingers back into claws as it ripped free as a cascade of blue-white lightning, convection currents heating the once-dark chambers to a sweltering fury. The bolts lashed out toward the Jedi, angry, alive, ready to rip through every cell in his body.
The old man rose to a knee, shouting with effort as his hands came forward, the Light Side filling him from the Nexus' depths as his iron will pulled the lightning storm into a tight, volatile ball.
Standing, his muscles quaking with effort, his old bones creaking and grinding with every movement, the Cleric pushed his way into a stern stance, the power of his indomitable convictions forming a bulwark against the unrestrained fury of his foe. The Nexus dove its power into and through them both, washing away fatigue, offering unlimited, uncontrollable power; through them, it wove power enough to heat the chamber's walls to a dim red. Through it, they brought forth the full force of a conflict older than both of their Orders.
Liam held fast against the tide, his body screaming in agony as his mind held true, the Light seeming to elevate his features, melting the age from the hard lines of his face. The Force spoke to his body's sacrifice, to the righteousness of his cause, bringing him peace as his flesh knew only turmoil. All the while Turel screamed in pain and rage, his fingers blackening, stray bolts biting blisters into his flesh and burning small holes into his garb. The iris of each eye slowly bled to an orange-gold, as bloodshot veins seemed to stain the whites of his eyes black, veins protruding and swelling unnaturally beneath his skin. He poured all of his hatred, his fury, and his anger at Liam; yet it was not enough. For all his fervor, he could not hold; for all his rage, he was not stronger.
For a moment, a shard of eternity that seemed to freeze in the minds of both combatants, their powers seemed to reach a level of equilibrium; for that moment, and that moment alone, the Balance was personified between their wills, held aloft as the pair became Light and Darkness incarnate for but a moment.
With a roar of effort, Liam threw his hands forward, the lightning ball in his grasp flashing forward. Then, it exploded, hurling Jedi and Sith alike across the cavern's walls.
Bouncing, skipping, Turel's body knew only agony as the energies that had funnelled through him escaped his grasp, stray voltage coursing into his frame for but a moment before he hit the cave wall hard. Groaning, coughing, he dragged himself up to his blackened hands and bloodied knees, trickles of red emerging from dozens of cuts and scrapes across his frame. Shaking like a leaf, he looked up at Liam through blurry eyes, to see the Jedi standing slowly, taking up his lightsaber hilts and activating them. Determination was clear in the man's face as Turel's vision cleared, his eyes alive with challenge.
Sorenn's anger wilted beneath fatigue; his shoulders slumped in defeat. "Go on, then." He sighed, tears streaming from the corners of his eyes. "Do it. Kill me."
For a moment, Liam's face softened, before determination returned; his sabers slurped back into their hilts, before he clipped them to his belt. "Turel, you have betrayed all those you once stood beside. You have forsaken the Light, abandoned your post, and given in to the Darkness you swore to destroy." His eyes, while sad, held strong. "You will live with that." Turning, he slowly, shakily, strode toward the cavern's entrance.
Anger again quickened in Turel's heart, his face scrunching into an expression of pain. His breath caught, his chest wracked with sobs as malice and betrayal, pain and guilt, sorrow and regret swelled up inside him. Pushing himself to his feet, he rushed toward the Equite, snatching his lightsaber up and igniting it. Roaring, he brought it high, an overhead chop aimed for the old man's back.
In his rage, he didn't even see the Equite's hand move, nor his footwork as he twisted and struck; a blue lightsaber blade burst to life, its tip carving up and through the ribcage of the Dark Jedi Knight. Its edge severed his spine, and he went stiff for but a moment with a grunt, looking down to the hilt buried in his chest.
Then, with a weakening cry of pain, he went limp. Liam let the blade in his hands die, dropping it with shaking hands as he caught the Jedi, easing his fall and cradling Turel's head in his lap. "Hush, now," he said, tears of his own streaming from the corners of his wizened eyes. They dripped down onto Turel's cheeks, as the man's eyes widened with disbelief, the horror of the end before him. "Be still, son. Your pain is done." With a quaking hand, the ragged Equite brushed aside Turel's own tears, a look of anguish in his aged eyes as he watched life slip away. "Be still."
The Knight gasped a breath, all he had done in this life flashing before him; his last sight was the face of his mentor, solemn and serene.
