At least Odan-Urr could have given me time to change
Ryan at least tried to look presentable in so fine an establishment by drawing his cloak around his armor. He hated being improperly dressed for an occasion and without his velvet and cravat he felt like a ham-fisted brute among the civilized. The order from Odan-urr was urgent, however. He was to find the House Arcona Sith and retrieve a valuable datapad from him containing intelligence on Collective movements.
He didn't like it. Ryan was an Arconan once, long ago and the Dark Side almost cost him his soul. That was behind him now, but he always worried that the shadow would claim him once again as one of their own. He remembered how easy it was to be tempted by his passions. To use evil means for good ends and how destructive it could be to himself and others. He wanted to make this quick.
Checking his crush-gaunted hands and wiggling his fingers in them, he stood at the bar and looked warily around. Most of the assembled of sundry species and dress appeared to be the typical high-rollers and sybarites of an establishment catering to the wealthiest of the Smuggler's Moon.
“Wow... nice attire.”
Ryan visibly winced as a shadowy figure had slipped next to him at the bar without him even noticing.
“We can't all be the height of fashion between missions, Arconan.” Ryan turned and observed the spiky black hair and tanned features of the smirking figure beside him.
“Oh we can. In Arcona we'd rarely be so gauche. Much less making our first move in the finest gambling establishment in Nar Shadaa towards the bar as opposed to the sabacc tables,” the Sith replied.
“I don't gamble. Were you hoping we'd have a battle of wits there like a spy holovid cliché? The sabacc game is like a weird metaphor for this conversation we're having right now? I don't need to flash credits, I was born to class. Now hand over the datapad.”
Magik's brow furrowed, somewhat confused.
“What datapad? I was told you had valuable information regarding the Collective and that you'd likely to refuse to give it up.”
“I have no such thing.”
The Sith sighed. “That's what they said you'd say.”
With a flash an Inquisitorius stiletto sped towards Ryan's throat, looking for a place it wouldn't be turned by the Jedi's armor. Ryan's hands moved with practiced speed, quickly grabbing the attacking arm and wrist, crushing and wrenching the now pinned shoulder and arm and sending the stiletto skittering across the bar floor. The Sith seemed surprised at this, but coolly slipped from the grip with practiced deftness and zig-zagged backwards as Ryan missed with a crush-gaunted right cross to the Sith's smirking mouth. Ryan pursued, desiring not to lose distance as he followed with a powerful push kick to the mid section. However, the Sith's retreat took a lot of the force from the blow. Slowed by his armor, the Jedi failed to catch Magik as he slipped away.
If only I were dressed like a civilized man
Safely beyond reach, the Sith retaliated with a series of lanvarok disks from a wrist launcher that sailed through the air, neatly cutting a glass near Ryan in two, barely disturbing the likely highly unaffordable contents. Ryan proceeded to attempt to move for cover but the disks seemed to bend around tables and bystanders nimbly in impossible arks, two striking Ryan and ricocheting off his armor with a screech. Maybe fashion wasn't everything, after all.
To the side, an Aqualish gambler decided to seize the opportunity caused by the sudden brawl and commotion by beginning to furiously scoop credits from the table only to slump dead from a blaster bolt to the temple, the smoke from the wound all the more dramatic from the blue lighting. All Chaos proceeded to break loose as the Jedi and Sith warily watched each other across the bar as patrons drew blasters and proceeded to shove as credits dropped from the dead Aqualish's hand, ringing on the floor like a morbid jackpot.
Positive Takeaways
Realism
You do a good job of factoring in the weight of Ryan’s armour into his actions. To ensure this continues I would note the loadouts of both characters, especially armour tier before writing a post.
Can Be Improved
Story
In particular, of the 686 words in your post, only the last three paragraphs involve combat, one of which doesn’t involve Ryan and Magik. The first post is supposed to set up the conflict but has to strike a balance between exposition and combat. I would recommend planning the post before writing to better achieve balance.
