He was not interrupted throughout his response. Perhaps that ought to have unnerved him, as though what he was saying was somehow unsatisfactory or wrought with disappointment, but instead it simply bolstered him. It was true that his words were concise, lacking in true detail, but he doubted very much that his Master wished to hear every little thing he'd done. There wasn't time enough for such a recounting. Even so by the time he was done he felt as though he'd just bared his soul.
It was good then that Maliphant found it all satisfactory. That he was, in fact, gladdened to hear of the muses he'd wrangled.
But it was what came next that shook the boy, truly. His loyalty and competence had never been in question? Was this just another thing in life which he had made far bigger than it needed to be? Something he'd built up in his mind, and allowed to bleed intrusively within? He'd gone looking for approval, just as he'd gone looking for some way to make himself worthy of both his label of Father and Son, though neither had been requested of him to begin with. Self imposed...
"You will always be more than a guide" he retorted, and all at once the strange outward façade he was looking upon did not seem so foreign or strange. It was his Father, regardless of how he appeared, it was his Master. He found that he could meet those stony marble eyes without reluctance, he did not cow or seem unnerved.
What he did notice though was how the throne he sat upon seemed to alter his state, even if only a little. Arcturus could sense the shift in emotions, and indeed the darkness permeating, and found within himself a small modicum of relief which he would not draw attention to. He'd sworn to leave the matter of Maliphant's state alone, and he would honour those words he'd uttered.
The lesson was met with a soft inclination of his head. "I shall strive to keep such a lesson in mind, Father," he assured the man, knowing better than to simply outright promise it to be so. It wasn't always easy to see how much you were reliant on others, after all. But doing his best was something he could truthfully stick to. Arcturus couldn't help but ponder on the strength he himself held. He was no warrior, and in truth he wasn't even much of a sorcerer, he meddled with things that most Sith overlooked, tampered with trinkets and artifacts and dangerous facets of the Force which would just as readily backfire on him than work as intended.
Still, strength had many pillars.
As he was caught up to speed with not just the state of his Master but of the Sith's place in the Galaxy, Arcturus made mental notes. Their sphere of influence, their nearby enemies, and indeed the presence of the Worm locked away inside a biological prison. Yet it was the threat of splintered factions and infighting which seemed to be the real source of unease.
It was true, with so many creeds and beliefs and varying methods it was hard to keep Sith unified. Some might argue unification went against their very core, though Arcturus was not among them. For all he'd suffered and seen, and all he'd done, he remained something of an idealist at heart. For better, or for worse.
"I will do whatever I can to aid in this, Master," he stated, "Tell me what it is you would have me do, and I will see it done." Untrained Sith could be molded and forged, incompetence could be tempered out with enough time, and those who believed themselves to be more than they were? Well... It was never too late to knock someone down a few pegs. The Triumvir of course weren't something he could tackle, he was nothing when compared to Carnifex and Ophidia.
With all of this roaming around his head, another thought popped up. "I would like to seek your permission, to train Rhiannon." He was an Apprentice, and it wasn't normal for an Apprentice to take on a student - even if he'd done it before - but she needed guidance, a ship in a storm without a lighthouse to beckon her, and he wanted to ensure her education was ample.
In many ways he didn't want to entrust her to those more complacent or overzealous Sith. Those who, as his Father had put it, were incompetent, or haughty.
