Ravus was more than prepared to receive the anger. It was how most reacted to his presence, after all, the world over. There were no friendly, understanding faces; there was only ever disdain at best, disgust and anger at worst. He did deserve it, certainly. His hands were no cleaner than any other Imperial, though he were of Tenebraean blood.
That there was not any anger did come as a surprise, though years of cruel schooling in the ways of things ensured that he kept it very hidden, his expression as it always was: calm, placid, wary.
He did allow a subtle bow of his head, the faintest nod. He had been trying to protect his sister and his people. What could he have done if he'd been allowed even a fraction of the power at King Regis' fingertips? He could have laid waste to the war, put an end to the fighting that devoured all sides. He could have averted his sister's fate.
He could have freed his homeland from the clutches of Niflheim, and he could have freed the people of Niflheim from the clutches of Gralea.
It was worth the price of his arm. It would have been worth the price of his life because the way Ravus saw it, no one else seemed willing to do more than drive Lunafreya and Noctis to their deaths as ordained by so-called Gods.
"You have my thanks for her survival." Gratefulness did not often leave Ravus' lips but he had seen the man at his sister's side, had seen him escort her and Regis out of the doomed throne room. Lunafreya, too, had spoken briefly of the brave Glaive who had, as far as anyone knew, given his life for not only the Oracle but all of Insomnia.
"Frankly," he began, then let out a sigh that was world-weary and exhausted. "I don't think anyone truly cares for the world as a whole. They're all too focused on ensuring that an asinine, nonsensical prophecy come to pass." Thoughts he had expressed many times as a boy to his mother, thoughts he had expressed at least once to his sister, but none heard him, so he learned to be silent.
"His Majesty Ravus nox Fleuret of Tenebrae." That introduction, that he left out any mention of Niflheim and his Imperial rank, spoke far more than any confirmation he could give, and he made sure to put emphasis on his homeland.
"It is a pleasure to meet you." The sword, once it seemed there would definitely be no fight, was slipped into its scabbard at his waist.
