Tra’an snarled, furious that the Pantoran had managed to catch him off guard. Laren smiled, knowing he had dealt the Dark Jedi an unexpected blow, both physical and of pride.
“Reith, prove you aren't a coward. Fight me without that fancy lightsaber of yours.”
The Dark Jedi easily called his dropped lightsaber back to his hand, initially ignoring the bounty hunter’s taunts. As he activated the glowing copper blade, he brought it in front of himself. Laren loosened his stance, making himself ready for the Kaleeshi's powerful strike. It would take every ounce of Laren’s skill to come out of such an engagement alive.
In an unexpected move, Tra'an suddenly deactivated his lightsaber and safely stowed it away. He set his right leg back and kept his left forward and bent. His arms were placed by his side, elbows contained near his torso, and strong hands pointed forward. They're ready to grab, Laren analyzed in his head, recognizing the juggernaut's open palms. The Pantoran would have to use speed to overcome his fellow Plagueian.
Laren crept forward, his legs bent and his stance kept low. As the gap between the fierce Kahleeshi and the spry bounty hunter closed, Laren visually probed for an opening in his defenses. With less than a pace between the two combatants, Laren opened himself to the battle and engaged his foe.
He launched a short flurry of quick strikes, testing the goliath’s defenses. His attacks were ultimately unsuccessful, and Tra’an repelled his advance with a stiff push. But Laren was patient. His will to understand his opponent’s strategy and emotions was paramount to his chance of survival.
Laren advanced once again, seeking to draw his opponent into a confrontation. Laren and Tra’an both stepped forward at the same time, surprising each other at their mutual boldness. The large Kahleeshi gripped at Laren’s shirt, desperately attempting to wrestle him into the ground. Laren brought his right arm up in retaliation, adeptly knocking away Tra’an’s arm. Using this opening, Laren brought his right arm to bare in a ferocious straight lead, striking Tra’an just under his armpit. The larger humanoid briefly cried out in pain, though he quickly collected himself, stepped back, and reformed his defense.
As Laren readied to attempt another series of strikes, Tra’an roared in defiance. Taken aback at the intimidating sight, the Pantoran faltered and slowed in his advance. Tra'an seized the opportunity, hoping to charge into an attack. Laren saw him raise his dominant hand, his palm open and facing forward. Moments later the Pantoran felt as if he was hit by an invisible brick wall. The power of the unseen force sent Laren airborne and over the side of the building, falling to the street below.
Twisting in mid-air, Laren hit the ground in a roll, distributing the impact as he skid across the ground. When he finally came to a stop, his back was to the surface, while his scarred face was distorted in immense anguish. Instinctively, he forced himself to wiggle his fingers and toes; a survival method taught to him as a slave in order to test bodily functions after a severe punishment. Everything moved, albeit slowly and foggily, and extremely painfully. His head had smacked into the pavement, and he was lucky to even be alive after such a drastic fall. But through the immeasurable pain, he willed himself to sit up. He needed to see what was going on.
Tra'an had reactivated his copper-hued lightsaber, and was descending the side stairwell of the building. He leapt down the final flight of stairs, spinning to look at Laren.
“There he is! Yousa stop now!”
Tra'an and Laren glanced at each other, having forgotten about the Gungan security forces. The guards were converging from various streets, perhaps twenty strong and with more on the way. In their hands were cestas, loaded with the surprisingly dangerous ‘boomas’, ready to launch a volley at Tra’an and, Laren suspected, himself, too. But an opportunity had presented itself.
Laren redirected the Gungans’ attention. “That guy is a monster! Shoot him!”
The guards didn’t need much convincing. “Fire!”, came the Gungan commander's call.
As the boomas were launched in the air, Laren moved to escape the hulking Dark Jedi, dashing away from Tra'an, who was expertly dodging and deflecting the spherical projectiles. Tra’an’s focus had been momentarily drawn to the Gungans, and as he turned to look back at the spry Pantoran, he saw his opponent running full tilt, away from the battle.
“You coward!”, came Tra’an’s booming voice as he gave pursuit.
Laren paid the comment no mind. As he reached the base of an intersection, he drew his hand blaster. He turned to look at Tra’an, who was bounding through the street in pursuit, expertly dodging the Gungan weapons being hurled his direction. His focus and rage was once again levelled upon Laren, and the bounty hunter was hoping it would stay that way. He wanted to overwhelm the beast with too many opponents in a wide street. But first I’ll have to find one.
Laren spotted a nearby alley. He sprinted away from the advancing juggernaut and began running down the slim opening. Two Gungan security personnel stationed at the opposite exit ordered him to stop, but Laren raised his weapon and fired two bolts of plasma over their wide energy shields, hitting the unsuspecting guards in the head and neck. Laren didn't bother to look back to know if the Dark Jedi was following him, as he could hear the lightsaber hum with every powerful stride. Bloody hell, do not stop running.
With every turn, every metre sprinted, the dedicated Dark Jedi was gaining on the haggard Pantoran. The juggernaut held true to his reputation, cutting down or barreling through any resistance in his path to get to his rival Plagueian. His lightsaber cut through flesh and narrowly deflected or cut at the boomas now being hurled at him from every direction. Laren was still ahead, desperately weaving in and out of side streets and small alleys, hoping that an opening to trap the Dark Jedi would present itself.
Instead, Laren made an abrupt left turn and found himself at a dead end. He looked around, desperate to find a way out. The walls were curved, and too high for Laren to leap over. Nothing. Knowing that the battle was nearly over, Laren took a crouching position along the right-hand wall, hoping to catch Tra'an by surprise.
The armoured Kahleeshi rounded the corner with his lightsaber at the ready, but Laren fired anyway. He squeezed the trigger as fast as he could, sending blaster bolts flying through the air, bound for Tra'an. Some went wide, some were deflected, but the Dark Jedi roared in anguish as two bolts found their mark: one in his abdomen, and one in his left leg. But the Dark Jedi didn't stop moving, but rather his movement seemed to quicken and was further augmented by his brewing fury. He slashed at Laren as he came into range, but the Pantoran narrowly dodged the blow and landed against a wall. This time Tra'an stabbed, catching the Pantoran by surprise. He caught Laren through the chest, and the bounty hunter slid down the wall of the alley, cupping the charred flesh where Tra'an had just stabbed him.
Standing victorious over his opponent, Tra'an asked, “Why are you here, Laren?”
Laren raised a finger on his left hand gently, pointing at Tra'an. “Watching you -- for the Inquisi-” Laren couldn't form the words, as the effects of his internal injuries began to take hold.
“It's a wonder how a disgusting basic like you made it so far in our Brotherhood.”
“It's a wonder -- that you -- are still alive,” Laren replied between coarse breaths, blood beginning to fill his throat and lungs.
Above them and behind them, Gungan security personnel were waiting for a chance to strike. But their fear held them at bay, fear of the beast that had slaughtered so many of their own. And though Laren had wanted to avoid dying and being arrested, perhaps the Gungans could finish the job Laren had started.
The Kahleeshi looked through the amassed faces of his Gungan enemies. His lightsaber was held in front of him, ready to attempt to defend his life from such overwhelming odds. Laren watched, even as he was fading into unconsciousness, how the man stood in defiance of anything that stood in his way. He wasn't a graceful operator, but his brutality got the job done.
“We will meet again.”
Though the man was wounded and exhausted, he had one final trick up his sleeve. Using the last of his strength, he leapt with all of his might. Boomas and spears flew through the air attempting to hit the surprisingly graceful Dark Jedi, but to no avail. He landed on the tip of a nearby walkway and began running, with the majority of Gungans following.
Two unlucky souls were left to guard the nearly unconscious form of Laren. They didn't bother to remove Laren from his blaster, and so he fired at their backs, dropping the two guards in a heap.
Now how the hell will I get out of this mess, was Laren’s final thought before he drifted into blackness.
Syntax
This would have been a good spot to use suspension points (ellipsis), where his being so... different went unremarked upon. In this case suspension points communicate how the narrator pauses to search for the right word.
"Kaleesh" (so the Kaleesh's eye) is the form commonly used in canon sources, as far as I could tell.
A minor typo.
You later write it as "the mercenary". Either way is acceptable, but take care to be consistent within the match.
Repetition of "as". The sentence as a whole might have better flow if it was split in two.
Realism
Adding the sense of smell to your descriptions is a good way to add depth to the scenery. However, in this case the Venue is under the freshwater Lake Paonga. Watch out for little details like that.
