Nothing but the end, and the end was an eventuality.
The being known as Nihilus, that had once been man and whole, was not the man anymore, but people changed, lives went about, and so did worlds. He, however, was far more than what the Force had given him.
There was a faint recollection of what he once was, but Nihilus was not indebted to the past of what he used to be, nor desired it, for there was nothing left but hunger. There was only then, and the future in which there was nothing, just hunger. Only he felt the endless pang of his hunger, and a desire to feed and grow. He fed on the few lifeforce of others touched by the Force or otherwise, but the pang of hunger remained soon after he had his fill, and he was known as the Lord of Hunger.
The Lord of Betrayal came first to him with an offer, and with the Lord of Pain, they formed the Triumvirate. But all Sith saw each other as rivals for power, and Nihilus in his pang of hunger had already formed ways he could devour Betrayal and Pain, a bottomless pit that could almost never be sated, and would consume entire galaxies until he would eventually be alone in the endless cosmos.
Onboard the Ravager he silently stood and Marr, his own apprentice, sent to eliminate the disturbance he felt through the throes of his own hunger. Soon after however, he felt only yet another presence, far stronger, his desire to feed on this new presence he felt. Yet as he felt it through the Force, he could not see it. It appeared everywhere at once outside his own cruiser, yet it did not show itself.
Nihilus reached out, yet he could not feed on what he did not see, only through the pervading emptiness of space itself in his own transport. Every use of the Force, as he attempted to probe the mind or attempt to dominate this new unknown resulted in failure, for this presence seemingly rebuffed his attempts with not the Force but something unknown and perhaps just as powerful.
It came to him then, a mist of indigo behind a formless body of an orb and what appeared to be eyes. Barely, he could make out the true presence of this unknown powerful being, an anomaly or something far unknown, powerful, yet not even the Force. He attempted to feed off this presence, wanting to sate himself, but it resisted his attempts of even the Force itself, and he was unable to feed off it. Their presences clashed against each other in a brief struggle, yet could not overpower the other, accepting the stalemate as if they knew each other almost immediately.
Nihilus felt its presence then speaking to him in his endless gorging of hunger, and what remained of Nihilus now spoke in the ancient Sith tongue within his mind.
Nothing in the end, and the end would have nothing. An endless scope in which there was no sense or purpose.
What purpose was there to feed?
The question lingered in his mind, questioning, and yet it did not feel mocking. It felt as if… understanding, knowing, as if it knew his desire to feed, yet the end was all the same for him. For the Jedi. And for the Sith. There were no such concepts of hope. Just an endless cycle until the galaxy and universe consumed itself.
Then it was gone as it had appeared, and Nihilus was alone once more, the presence vanishing faster than even he could detect with the Force. There was no fear in Nihilus' mind, as he was beyond what used to be human, but only thoughts of what was the end.
Nihilus stared into the abyss where he once saw the presence, and continued to do so, trying to reach out with the Force in an attempt to feel this presence once more that he grew a mild curiosity in, and failing, his own hunger in the void of nothing filling him again as his focus returned back to the shift in the Force of Marr's failure, until Meetra Surik came for him in amidst the chaos of battle against Jedi and Mandalorian on Telos IV.
Nihilus, defeated and weakened, only thought of both his hunger and the presence once more, and understood what the presence had meant before the blade of his former apprentice, Visas Marr, decapitated him.
His end.
