Clarinda knew who was at the door the instant she heard the three sharp staccato knocks, and her heart leapt up in her throat for a moment as she rapidly glanced around the room to make sure that the room was clear of any of her forbidden notes. Thankfully, she'd been waiting for Adeline to arrive before they resumed their studies, and Clarinda had a plotter's instinct to keep her secrets hidden as much as possible. Not that it mattered-if the Machines had sent Shepherds directly to her bedchamber, they must know what she was planning. But she could at least plead innocence for a time.
It must have been Adeline who betrayed her. Clarinda couldn't let herself think about that now. Instead, she gathered her skirts in her pale, callused fingers and swiftly crossed her apartments to the double door before the Shepherd could knock a second time. Only the guilty dragged their heels when the Shepherds came calling, they said, although Clarinda knew full well that 'the guilty' were pretty much whoever the Machines said they were. No one in the Court of Callisto had enough purity to withstand an interrogation of their private activities; they were all devious schemers to a man.
Or a woman. Damn Adeline to Sinope and back! She opened the doors wide and dropped immediately into a curtsy at the sight of the two tall, solidly built robots, each with a chassis of dull grey steel and smooth, expressionless silver masks for heads. They looked down at her from a height of almost ten feet and said in unison, "Your attendance is required at an audience with the Machines of Loving Grace." Their voices somehow managed to be impatient and monotonous at the same time, as if they were irritated at having to cross all the way from the Central Tower out to the Periphery of Lesser Nobles just to handle a single complaint.
Clarinda knew better-she had schematics hidden in a concealed drawer in her dresser that told her just how little personality the Shepherds truly had. But knowledge didn't help her escape the feeling of dread and anxiety that clenched at her gut and made her babble out, "Of course, my lords. I'll need to attend to a few of my obligations, naturally, and the journey to Central will take some days to travel in comfort, but I'm sure the Machines of Loving Grace will understand. If you'll excuse me, I should begin packing at once-" She moved to close the doors again, but of course the Shepherds caught them in their steel fists and held them without any apparent effort.
"There is no need for delay," one Shepherd said. "The Court has been informed of your summons," continued the other. "Your duties have been temporarily suspended until the audience is concluded and your capabilities reassessed," the first one added, its words fitting smoothly and neatly into the gap left by its compatriot. Clarinda could hear a number of other little voids and absences in their speech, things left unsaid that Clarinda was more than capable of filling in herself by inference.
The other nobles now knew that she was accused of rebellion by the Machines of Loving Grace. Naturally, the courtiers would be falling all over themselves to scurry away from any potential ties with Clarinda, lest they be examined with the same scrutiny and found guilty by association. Even the highest and grandest Duke or Duchess served solely at the favor of the Machines; they gave power, and could take it away just as easily. Clarinda's time of influence, such as it was, was over.
And for them to openly discuss reassessing her capabilities... Clarinda shuddered involuntarily, her mind shying away from the implications of that statement. With an effort of will, she collected herself and turned away from the Shepherds' glowing red eyes. "Of course, my lords," she mumbled, her mind already racing as she stumbled in the direction of her wardrobe, almost tripping on her skirts in her haste. "If, if you could simply give me a moment's privacy, so that I might change into something more suitable for travel?" She didn't believe for an instant that they would humor her request, but it gave her an excuse to get away.
Perhaps she could reach the laser welder she kept concealed in the false bottom of her hatbox, use it on the metal skulls of the brutes down at the base of the neck where it was thinnest and make a run for it before the Machines could send more. The Periphery was filled with hatchways and service tunnels leading down to the vast engines that maintained the floating city; if she could hide out down there and contact some of the like-minded courtiers, get them to bring her food and smuggle her notes to her, she might be able to find a way to-
Clarinda's fantasies of escape ended abruptly as a massive metal hand clamped around each of her wrists, not tight enough to hurt but firm enough to erase any question of pulling free. "Your attendance is required immediately. Delays will not be tolerated. There are significant questions regarding your loyalties to the Machines of Loving Grace that must be answered at once." They lifted her bodily off the floor, and Clarinda's composure finally began to crack.
"M-my lords," she stammered, her feet kicking wildly as she struggled vainly in the Shepherds' grip. "I, I don't know who's been telling you these... these perfidious lies! I am loyal as always to the Machines of Loving Grace! Their beneficence keeps us in the skies, their servants feed and care for us, their wisdom guides us through the ages since time long forgotten!" Three hundred twenty-seven years ago, if the forbidden histories were true, but Clarinda knew better than to even hint at knowledge of a time before the founding of the court and the dominion of the Machines.
"I-I-" Clarinda tugged helplessly, but the Shepherds walked her back out of the room between them as if she was nothing more than a child's doll in the arms of a possessive toddler. "Is, is this Adeline du Lac's doing?" she whimpered, her voice whining and desperate and suddenly bereft of courage. "Because she, she's been plotting against you, lords! I don't know what she might have told you, but it's all false, every word of it! She, she wanted me out of the way so I couldn't warn you about her schemes, she's seeking to find your weaknesses, she-"
The Shepherds stopped next to her dresser. The one on her left, closest to the antique, looked over at her. "The Lady Adeline stated that we would find forbidden documents within these furnishings," it said, its voice utterly disinterested. It swung the fist not holding Clarinda down hard, smashing the desk to splinters with a single blow, and extracted a sheaf of notes from within the ruined pile of wood. "It appears that her intelligence was accurate. We will deliver you to your audience now." And with that, they left the room, Clarinda helplessly in tow.
She still clung to the momentary hope that there would be chances along their journey to escape-rest breaks, meals, chances to sleep, times when they would have to let go of the tight and unbreakable grip around her wrists-but that hope died when they walked over to a section of the castle wall that looked no different from any other and pressed on an indentation that Clarinda knew for a fact hadn't been there a moment ago. The wall opened, revealing a short passage that she recognized from the city plans as an 'air-lock'. She understood just enough of its function to scream before they stepped inside, the door sealing shut and muffling her terrified shrieks.
"M-my lords, please, please no, I... I'm a loyal servant of the Machines, I never, I... Adeline, she must have planted those notes, please, I don't want to die!" Clarinda knew she was incriminating herself further with every word-a truly loyal noblewoman would see this only as another one of the miracles of the Machines of Loving Grace, a passage created by their will alone for their servants to use. They would have no idea that nothing lay on the other side of the outer wall but a thin, unbreathable atmosphere of carbon dioxide, so cold that merely inhaling it would shred Clarinda's lungs. Only a criminal, a dabbler in forbidden knowledge would be as terrified as Clarinda right now. But that didn't change the bone-deep awareness of her own impending demise that overwhelmed her usual steely confidence.
The outer wall opened. But Clarinda didn't die. A shimmering, invisible wall of force sprung up instead, enveloping her and the Shepherds who bracketed her on either side. Sheer astonishment abated the terror faster than relief possibly could, Clarinda's scientific mind working at a kilometer a second as she mentally annotated the diagrams and documents gripped in the robot's fist. The emergency energy projector wasn't a weapon at all. It was a defensive measure, designed to block attacks and seal out harmful environmental factors. It must have been useful, back when Callisto was first being settled, before the Machines decided to protect humanity from themselves. Clarinda wished she could tell someone about her discovery.
But it seemed likely she'd never get the chance. The Shepherds stepped out into empty air, their feet glowing bright blue with strange energies as they flew at speeds almost faster than Clarinda could contemplate from the outer ring of the Periphery down and inward to the Central Tower. She understood at last how the Shepherds could seem so inescapable, their arrival coming apparently right on the heels of the Machines' decisions; not only were they able to move at speeds that defied thought, but they had no need of following the winding paths of the floating city's internal geography. They could simply step out an air-lock and zip from ring to ring, tower to tower, whenever they chose.
