“Go suck on some more Gungan-spit,” Christopher retorted, keeping himself perfectly still.
Halcyon shook his head ever so slightly, but it was enough to convey his current displeasure. Unmasked, he knew his assailant having served with him in Taldryan. Christopher was a soldier through-and-through, so he already knew the answer to that question.
“I guess Odan-Urr is finally getting around for payback, now that I am on my own.”
Christopher’s reaction to the statement was telling. “You didn’t know why you were ordered, did you?” Halcyon asked. As Deputy Grand Master, Halcyon had lead the attack on New Tython many years ago. He had killed their main ally, and his brother, Michael Halcyon. It had taken Odan-Urr years to rebuild before finally fleeing to parts unknown.
“You can still go suck on that Gungan, Halc,” Christopher growled, not giving the older man the satisfaction of his curiosity.
Halcyon had wanted to continue goading Christopher, but it had appeared that the Gungan military had regrouped and were beginning to converge on their location. Halcyon began to move on instinct, his lightsaber in position to cut the enemy down, but an internal force stayed his hand. He had never second-guessed the killing of others, but since leaving the Dark Council he had started down a new path. While he knew he would never be one with the Light, he knew he was no longer in the grip of the Dark.
Christopher’s mind was running through the possibilities. He had heard the Gungans getting closer as well, and knew his time was short. He saw Halcyon’s initial movements and all of his possibilities now converged to his death. The last thing he would have expected was hesitation on the part of an Elder and Dark Prophet, but that is exactly what he saw on the green-haired man in front of him. Training and experience took over as Christopher used that moment in time to launch himself upwards and forward.
He needed only two steps to reach Halcyon, but never slowed as he plowed through the space that Halcyon was occupying. Halcyon’s body, of its own volition, turned in time to avoid a direct hit, but Christopher's armoured shoulder still caught him in the arm and spun him around.
Christopher never slowed as he eyed the next building. His grappling hook was out and the head of it shot out. The arrow-shaped head embedded itself into the top of the other building as Christopher jumped off the roof and swung himself against the side of the other building. Ensuring he had a secure hold on the grappling hook he began to climb up the side of the building, reaching the ledge and throwing himself over it.
Halcyon swore to himself as he shook the pain in his arm out. He had fallen to his knees from the collision, but recovered quickly. What needed to be done coalesced quickly in his mind as he chased after Christopher. Infusing his legs with the Force he leapt off the roof and caught the ledge of the other building, pulling himself up. Although no longer bound to the darkside, he was still intimately familiar with its uses and how to channel his own anger. Once more he pushed the Force into his legs, this time allowing him to nearly catch up with Christopher in only a few strides. With an outstretched hand he focused his anger and unleashed it, violet strings of energy bursting from his fingers and enveloping the Odan-Urr soldier.
Christopher fell to the ground almost instantly, skidding across the roof before coming to a full stop. His mouth was open in a soundless scream as Halcyon calmly walked over to him, never once releasing him from his lightning-grip.
“You tell your bosses to forget I exist. I have no quarrel with them. They send anyone else, and I will make it my mission that they all cease to actually exist. Do I make myself clear?”
Christopher shook violently, smelling his own flesh beginning to cook within his armour.
“Answer me!” Halcyon shouted in his ear, finally eliciting a nod from Christopher along with the first scream of pain.
Halcyon finally released Christopher from the deadly energies, before turning away and moving towards the other side of the roof. He leapt over the ledge just as the Gungan military began to converge on the rooftop, surrounding the prone human who lay on the ground, smoke wafting from his body.
Syntax
You need a comma here to separate the phrases.
This shouldn't be split by a semicolon. They are meant for two independent clauses that refer explicitly to the same subject. Also, the second clause doesn't work grammatically. Which is regarding the scuttlebutt and belief? That Pravus is dead or the Inq had stood down?
Unneeded repetition of "at least" here that doesn't enhance the writing.
You really like to use "Force" throughout this paragraph. Vary it up and keep the imagery interesting.
Structurally, this needs to be "of" instead of "to".
Comma is needed here.
Should be a possessive here, not a plural.
Story
The... interesting... locale setup aside, you do a good job of playing to the Aspect related strengths of both characters. That's a good thing to focus on in a match. Especially integrating it naturally.
