Some time prior to the current events:
Sith, no matter how far their birthplace, no matter how weak or strong they were, they all found their way to Korriban. Like flies to a carcass, they all swarmed to this place once or more times in their lives. Some seeking knowledge, others seeking power or both, but all attracted to that one thing in which the planet seemed to be drowned and drenched: the dark side of the force and like a moth to a flame, most got burned in the process, mauled and butchered by those of similar mind and disposition, as Sith did not like sharing their power and knowledge, not without anything to be gained from it. Darth Halcyon or Credius Arcosius Nargath as he was more commonly known beyond the sith empire's borders, was no exception to these rules. He had been on Korriban once, a long time ago with his own master; Darth Alepsis. It was there that he first saw the true power of the Sith, finally learning more than he had ever done before and it was also here on this planet that he had killed that same master, allowing her flesh to turn to dust upon those bloodsoaked sands that envelopped the planet as a testamental blanket of its dark, yet glorious history.
His ship; the Valkan Dagger, slowly descending near the spot where he had bested Darth Alepsis, where he had decided to forge his own path, his own destiny and where he had finally understood that he did not need to limit himself nor his ambitions. "Still such a wasteland..." As the sith lord's cockpit opened, the man jumped out of it, his feet carefully and gently touching the ground underneath, his armor shimmering in the dim, reddish light upon the planet, his eyes cold and white behind his mask, peering into the distance. "I feel it, there is a great convergence of the force not too far away."
Current time:
When coming near the cavern where he was certain the convergence was happening, Darth Halcyon got interrupted by some snotnosed acolyte thinking the approaching man was some part of his test. Jumping from a nearby cliff, the acolyte seemed to desire to cleave through the tall, cloaked man with his neon red lightsaber swooshing through the air. However, before the slightsaber could even manage to scorch the very cloak of the Sith Lord, his hand had already risen upwards and frozen the poor brat, forcefully levitating the child in mid air. "Poor little child, you have no idea why you are here or what you are supposed to do...but let me tell you this, you have no doubt failed your test, as the only trial on this planet..." For a mere moment, the connection seemed to be broken, the acolyte dropping to the ground with a heavy thud. "...Is to survive."
A ruthless, merciless stream of black lightning escaped the Sith lord's fingertips, the very color of the lightning displaying the sheer force of will the man put upon the force, to bend it to his will and to his desires. As flesh got desintegrated, bone crumbled and all what remained were the charred pieces of armor and a single destroyed lightsaber, the Sith lord sighed a heavy sigh, both annoyed by the fact that he couldn't just get around uninterrupted and also because he could feel the pain radiating through his body, that excruciating internal pain which signified his deep connection to the dark side of the force, telling him his body as a human is not nearly suited for the vast amount of power he was able to extripate from the darkness.
Popping a few painkillers into his mouth, Darth Halcyon lowered the mask of his helmet again and made his way into the cavern, eager to see what he would find at the location of this so-called convergence of the force. What kind of creatures, what kind of monsters would be there to behold?
