Lucine sighed inwardly as she observed the Clawdite's aggressive stance. In truth, she had been looking forward to this assignment. The idea of visiting Dromund Kaas intrigued her, even if it meant wasting some time searching for Pravus while she was there. She had been quite irritated when she realized that she did not have the temple to herself, and had reacted rashly. Now, the Clawdite wanted to fight. Wonderful.
I will not be able to get anything done with this fool hanging around, she thought to herself. Her eyes moved from the lightsabers to his face as she studied him carefully. Perhaps a softer touch would work. “No,” she said, her scarlet lips curved into a smile. “No, I do not want to fight.”
The Clawdite paused, taken aback by her sudden change in attitude. The lightsaber blades lowered slightly. “What?”
“I said, I do not want to fight,” Lucine said with a soft laugh. “It seems to me that we got off on the wrong foot. I am Lucine, and who might you be?”
“Blackhawk,” he offered grudgingly from behind the glowing plasma blades.
“There now, you see? Was that so hard?” The redhead purred. “And what brings you to such a forbidding place, Blackhawk?” The lightning flashed, as if to punctuate her words.
“Looking for clues about where Pravus went,” the Clawdite replied, his answer coming a bit more quickly this time.
“And are you having any luck?”
“Nah, I just got here,” Blackhawk said.
“Such a shame,” Lucine murmured. Her eyes went to his weapons once more, and she continued on before he had a chance to ask her what she was doing there. “Darling, it seems quite foolish for you to be standing there with your lightsabers activated while we are having a simple chat.” She drew upon the Force, causing it to give weight to her words.
The Clawdite frowned at her words. “I guess it's a little silly,” he replied in a sheepish tone. The plasma blades faded causing the shadows around them to deepen; broken only by the occasional bolt of lightning.
“That's better,” Lucine said. “You know, Blackhawk, it occurs to me that we have met before.”
“We have?”
“Of course! Surely you remember? As I recall, we had a lot of fun together,” Lucine’s voice took on a suggestive tone. As she spoke, she extended a thin tendril of the Force toward his mind, bearing a very pleasant memory.
Gradually, Blackhawk's look of confusion gave way to recognition and he grinned. “Oh, yeah! I can't believe I'd forgotten!”
Lucine waved a hand dismissively as she said, “Well, we have all been distracted by the recent events. I can understand how it would have slipped your mind.” She then gave him a lascivious look. “How about if you set down those lightsabers, and we can see about making some new memories? You know I am more of a lover than a fighter.”
The Clawdite narrowed his eyes as he considered her suggestion. But the redhead seemed quite harmless to him. If she tried something, he could always just call the lightsabers back to his hands. Slowly he set his weapons on the ground.
“Lovely,” Lucine said with a wicked smile. She enveloped the sabers with the Force, sending them flying off in opposite directions to be lost amid the foliage that had claimed the stone floor. “Yes, that is much better.”
Blackhawk's jaw dropped as his weapons skittered out of sight. He searched the undergrowth, but they were nowhere to be seen. With a growl of frustration, he returned his gaze to Lucine, only to realize that she had vanished.
Syntax
Should be a comma trailing the thought dialogue to "Blackhawk thought". It is much like "he said" but with thoughts instead.
This is just another form of "he said", but using "threatened". You should close out the dialogue with a comma since it is a single sentence.
Story
I'm not sure how you're trying to direct the reader's "eye" here. Are only we supposed to see this, or Blackhawk too? The way you follow it up with "when he looked back" could imply both. Either he glanced there, then away, then back or he looked there for the first time.
This post was rather succinct. You put good effort into an attempt at imagery to start with, but left the portrayal of the characters at a superficial level.
Realism
Lucine has +2 Telekinesis, at that rank: With an effort of will, the Jedi can concentrate for a second to freely manipulate multiple objects of varying shapes and sizes when not under duress. Do you think you depicted that in any way? She just throws her hand out and sends him into the pillar. Much too easy for the requirements.
