The Ancient
The illusion fooled even the strongest Sith, and he did not wait or watch Varin's display, but moved past him. Grimm was experienced with dealing with haughty, ill prepared Sith warriors. Once Varin reached the spot where Grimm had been, he was already blocks away. The corpses were inert, with no sign of the insects or their presence - indeed there had been none at all. Instead, Varin's lightsaber cleaved through empty space.
Where just a moment ago, a cloud of buzzing plague flies had erupted, only a courtyard with scattered dead bodies remained. No flies, no buzzing, no bloating, and least of all, no Sith. Grimm had told the truth when he said he had 'no time' for the fighter. His back to Varin, and a good distance away - the distance it would have taken him to walk past Varin at the beginning of the encounter to the end - he continued along towards the Space Port, grumbling and wheezing through his teeth.
He did still clutch his Soul Gem tightly, but his staff was inert, just a blackened songsteel shaft that acted merely as a crutch. His ragged body clamored forward as his hacking laugh echoed between the buildings. Lord Grimm had fooled the eyes of his enemy, and now his enemy lashed out with a series of powers that Grimm would not have even been threatened by, had he been at full power.
The ancient Sith Lord's mocking laughter erupted, echoing off the walls of emptied buildings as he left the scene. He continued forward, not caring to hurry his pace or change his stride. He was hunched over again, and hadn't even put down his collection of drafts and blueprints. So little did he think of Varin that he had simply... left.
The illusion left the stink of Sorcery around it, that sickly aroma of waning death that permeated the original illusion, simply fading, but it left behind the Sith Lord's aura, a gut-wrenching sense of unease that was the power of a Dark Side Adept.
There was still much distance for Grimm to travel. If Varin wished, he could follow Grimm again and engage him once more, but Grimm had showed part of his hand. Very likely he would just waste Varin's time again, playing with him like a loth-cat with a loth-rat.
"If thou art so keen on dying, boy, try thy hand upon me again," he cackled, but did not stop.
The power he had exuded before seemed to wane until it diminished into just a spark, a spark that Varin had to concentrate on if he even desired to sense the presence of the Dark Lord. Perhaps Varin would reconsider a Sith Sorceror who's illusions were powerful and skilled enough to fool even his Dragon's Eye.
"Buried, says he!" He mocked echoingly, "Necromancer, says he!" He laughed even harder at that. Grimm's power at it's height, could have ripped a solar flare from the very Sun above, and ended all life in the system. With the Soul Gem, he could manage - perhaps - a tenth of that power, but he had no doubt that it was enough to defeat a mere Apprentice.
Grimm's shoulders shook as he laughed. He clearly did not take Varin seriously as an opponent.
