Squinting through the twilight glinting down through the dense canopy of leaves, Tarvitz could barely make out the bulk of something massive half hidden amid the flora. Thickly muscled and crimson eyed, it looked like the sort of thing a Hutt would keep as his personal trophy monster. A whip-like tail was quietly uncoiling at its back, but Tarvitz’s attention was focused squarely upon the beast's pair of hateful crimson eyes and vast slavering maw. It was the sort of thing which really should not have been left out of any mission briefings, bare-bones as his one had been.
"Some forewarning would have been nice," Tarvitz quietly said, slowly unbuckling the heavy blaster pistol holstered at his thigh as they stared down the beast, "They aren't, perchance, known for simply walking away from potential prey I take it?"
"Unfortunately not," the Lieutenant Colonel answered, and Tarvitz heard the crunch of dead leaves as he edged away from the Force user.
No sooner had Andaris taken his first step, the vornskr bounded forwards, its growl rising into a bellowing roar as it hurled itself at Tarvitz. Throwing himself to one side, the Acolyte landed heavily, dragging his weapon clear from its holster and firing twice at the creature. Two searing beams of energy punched up into the treeline overhead, failing to find their mark. The vornskr landed somewhere out of sight, and he barely had the chance to rise into a crouch before it came about again. Slamming bodily into Tarvitz, jaws snapping as it came, the thing bore him to the ground.
Snarling, he Tarvitz tried to force himself backwards as it pinned him in place, claws scraping against the reinforced plasteel of his armour. Punching up with one arm, he barely managed to force its head aside as the vornskr lunged for his exposed neck, chewing into the ground next to him before reeling back for a second attempt.
"Help, damn you!" Tarvitz yelled out, wondering what in Corellia's nine hells Andaris was doing. He was answered seconds later, as several emerald green bolts screamed through the air. Several struck the beast, burning into the vornskr's thick sable fur and eliciting a shriek of pain, but a number of others missed entirely. One in particular punched a hole into the ground where Tarvitz's head had been moments before, leaving a charred patch in the dirt.
Biting back a curse, Tarvitz fumbled with his own weapon for a moment as he felt its weight momentarily ease off him, before jamming it into the vornskr's ribs. He pulled the trigger, listening to its screams as he unloaded full half of its power back into its side, opening a ragged fist-sized hole into its innards. It made one final roar, lunging for the Acolyte's face and missing entirely, before slumping to the ground.
"Looks like I chose the right Jedi for this mission," Andaris said with a smile as Tarvitz hauled the vornskr's twitching corpse off of him and rose to his feet "Though i'm surprised you didn't use a lightsaber at that range."
Andaris started to walk towards Tarvitz, before abruptly stopping, his smile faltering as the other man leveled the blaster at him.
"And I am surprised any mention of these beasts slipped your mind," Tarvitz said coldly taking careful aim at the man's head "What was it you said, again? 'There is no direct threat to us at the moment.' You just happened to overlook a creature all but tailor made to hunt Jedi?"
"Ka, please," Andaris said, raising his hands in a peaceful gesture "I secured the glade we landed in. I said there was no immediate threat-"
"Until we stepped away from the ships, and suddenly this thing emerges. A monster quite happy to ignore you in favour of me." Tarvitz interrupted, thinking of all that had happened since his arrival. He was hardly prone to bouts of paranoia, but the hours he had spent among the Brotherhood's great libraries had taught him a few key details. One of which was how the Brotherhood so often used duplicity and schemes to succeed in its goals, especially the elimination of potential foes within their ranks. He barely knew the Lieutenant Colonel and, for all his claims of serving Clan Odan-Urr, the mission had raised too many questions.
"Why are we here?" Tarvitz asked, momentarily considering the prior briefing.
"Excuse me?"
"It's a simple enough of a question - Why did you require the services of an Acolyte? I was told by Master Drachen that you had the full details of this task upon arrival. Surely there were better Jedi for such a task, so why did you require me in particular?"
Andaris paused for several seconds, seemingly unable to answer. That was enough. Tarvitz pulled the trigger and opened fire.
Syntax
You need to close the "a member of Clan Odan-Urr" parenthetical with a second comma. As a matter of style this sentence is awkward. You have said "the Odanite Lithar Andaris" or something similar to convey the same idea in a smoother manner.
While it is not a detractor and did not affect your syntax score, the use of non-English style quotation marks is jarring to a native speaker. Consider using the American/British style.
This sentence is fairly awkward, consider splitting it into two separate sentences. Also, you misspelled freighter.
Story
You left the details of the mission as an open question to the reader. Some mystery is a good thing but you never came back to this and it was left as a loose thread.
Matches between members of the same Clan are always a challenge. You have to come up with a reason for the two characters to be in conflict with one another. You had the start of a "testing the new person" conflict but didn't get to it in your first post. What you set up was more of a cooperative venture against the common threat of the vornskr. This would be fine in a run-on, but in the ACC duelist hall there has to be conflict between the two characters in every post (see the ACC rubric). This is a story detractor. You had the start of a solid conflict, you just needed to carry it a bit further to the point where the characters were actually fighting in your first post.
