The inferno roared with the pangs of its birth, reaching around itself like a million-armed demon, an orange monster shaped by wind and geography and chasing after the fuel it needed to grow. Suddenly, the grasslands were filled with a heat that even the relentless sunlight could not anticipate.
Timeros, by contrast, remained cold, ignoring his incipient triumph as he fell into a murderer’s focus and bore down on the lone Togruta, heedless of the sudden maelstrom of emotions emanating from Odan-Urr’s former potentate.
A mistake.
If the Entar had become colder still following the destructive rage around him, the Togruta seemed, if anything, invigorated. His first strike almost became his last as the Augur batted away his saber with absolute fury, her hammer blow accompanied by a primal scream.
The Adept stumbled, momentarily overpowered by the Jedi’s Force-battened muscles, feet finding little purchase against the flattened remains of the grass. Snarling, the Augur hammered again, her ferocity a sudden flare across the Arconae’s mind.
Furious. Powerful. Careless.
He avoided the bite of her blade, but only just, by flattening into a tangled mass of limbs, contorting out of the way and then scything upwards, slashing up with clinical precision at the Jedi’s knee. Yet furious as she was, the former Consul had not entirely given up on self-preservation. True to her rank, the Augur felt the blow before it could connect and hurled herself sideways, feet stomping out one tendril of flame as she rose, framed by the fire that threatened her home. Frenzied as she was, she paid it no heed, instead jumping forward with reckless abandon.
Had Timeros expected any mercy from the Jedi, he would have been sorely disappointed. The Jedi’s strikes fell quickly and furiously, sequenced in a pattern as rapacious as it was reckless. Her swordsmanship held no thought for escape or even survival: instead, the pack-minded woman held within her only the desire to destroy.
An emerald saber scythed in from the side. The Entar stepped lithely back, then forward, both lightsabers snapping together like scissors. Yet the Togruta was already ahead of him, mind peering into the future, and his blades hit only each other as she ducked underneath and jumped, crashing into the Elder shoulder-first.
The pair went tumbling over, hissing with pain as they rolled across the fiery landscape, flames licking at robes and exposed skin. Their sabers gouged the ground as they fell, both combatants seeking an exposed angle and failing, finally separating as their momentum ran out.
Neither could rest, however. The dark side whispered at Timeros, its putrid touch lending vigor and foresight as he instinctively rolled aside, knuckles whitening around his lightsaber as he planted his fist into the ground and pushed, hurling himself into the air and over a patch of flames. The Adept spun as he rose, seeing A’lora’s staff crash into the earth moments later, her lightsaber lying at her feet. She discarded the staff moments after and snatched it up, glaring daggers at the Entar as she advanced, ready to end him.
And then, she was ended.
As A’lora stepped forward, the Force came alive inside her mind, exploding with a fire that dwarfed the conflagration around her. Yet, caught in the throes of her mania, the warning came too late and a small cylinder near her feet likewise exploded. The blast hurled the Odanite backwards with its force even as a sticky, glue-like substance enveloped her and trapped her, fixing her motionlessly in place, her saber still outstretched towards the blank-faced Arconae.
Timeras watched the spectacle of his telekinetically-triggered grenade impassively, separated from the Augur by an arm’s length of rapidly-spreading flame. For a moment, he considered leaving the imprisoned Jedi to the fire that now wholly surrounded her; there would be a certain poetry in having her destroyed by the inferno that would soon consume her village.
Then, the Elder shook his head, resolve hardening. He holstered his saber as A’lora’s rage dimmed, her mania run out at last. “Make it quick,” she gasped.
He offered her a curt nod, and then reached for his remaining Westar, blaster bolts puncturing skin and proving that the Togruta, like the Turu-grass of her homeland, was likewise white on one side, red on the other.
Then, he turned around and strode away from the flames, speaking into his comlink as he left her village to its fate.
Syntax
This is an odd use of semicolon. Especially with the structure of the second clause. You would have been better served just using a simple sentence to begin with, closing with a period. The only real connective tissue here is the reference to "rustle".
Gotta pick one punctuation or the other here.
So, without "was the second" here, the second clause is no longer independent. Makes this a very minor error.
Story
There's not a lot of reason to be so wordy here. It comes across almost monotonous in its cadence.
The thing I liked most about this opening post is you didn't waste breath on getting to the fight (location or otherwise). Yet, you didn't sacrifice any story. You used introspection and narration to provide the context and motivation as you got into the combat. One might say you told the story through the combat. Nicely done.
Continuity
I assume his lightsaber deactivated when he removed his robe, but I hunted for any reference and couldn't find it. As far as the reader is concerned, the saber was still active.
