Precedent

vuler en anaj [ voo LEHR EHN ahn AHJZ ] , [ adj  ] — "truth in the gaze", used to describe someone around whom you feel  compelled to behave well because you sense that they can tell when you haven't.  From an old love poem; began as a noun (so-and-so has "truth in the gaze") and migrated to adjective form, ("so-and-so is  truth-in-the-gaze-ish").

      Silence. Always it was silence with him. Thirukedi's regard rested on his bent head. The first. Not of many, He knew, but enough. Always there would be enough.
      He lifted the male's face to meet those light eyes and traced one thumb over the cheek just below the rightmost. The skin creased beneath His touch: a smile, moving only half the male's face.
      "I know," Thirukedi said. He would be one of the few who could meet this gaze, and yet there was no regret in the servant's eyes. No sorrow, no fear of isolation.
      The male stood then and drew his cloak from his body, and then all his garments, until he stood naked before the Emperor, inviting His touch. Know me, the gesture said. Map me. Find the right place for your mark.
      So He did... ran His fingers over the entirety of that spare body, spare not like a sword but like a firing iron, meant to be thrust into a molten heart. It was not a beautiful body, but it was supremely purposeful.
      But again, Thirukedi returned to those eyes and lingered. Brushed a thumb beneath one of the dark-rimmed lower lids, watching the light glimmer off delicate lashes. He met this servant's eyes, and then reached... not for the shadowflower dye, but for the glove.
      The male's eyes rolled upward even as they closed. It was the only sign he allowed of his gratitude. They were of one mind. As the Emperor parted the flesh in a long thin line toward the first eye, He gave His subjects a gift: the illusion that this male's gaze was difficult to meet because they were marked with scar and poison... and not because they were his. It was a lie, but for the first servant of Shame, a necessary one. Or there would be no second.
