Sadeq sighs. "We'll go in using Kurs. I assume their Kurs guidance is active?"

"Kurs docking target support available to shell level three."

"Praise Allah." He pokes around through the guidance subsystem's menus, setting up the software emulation of the obsolete (but highly reliable) Soyuz docking system. At last he can leave the ship to look after itself for a bit. He glances round. For two years he has lived in this canister, and soon he will step outside it. It hardly seems real.

The radio, usually silent, crackles with unexpected life. "Bravo One One, this is Imperial Traffic Control. Verbal contact required, over."

Sadeq twitches with surprise. The voice sounds inhuman, paced with the cadences of a speech synthesizer, like so many of Her Majesty's subjects. "Bravo One One to Traffic Control, I'm listening, over."

"Bravo One One, we have assigned you a landing slot on tunnel four, airlock delta. Kurs active, ensure your guidance is set to seven-four-zero and slaved to our control."

He leans over the screen and rapidly checks the docking system's settings. "Control, all in order."

"Bravo One One, stand by."

The next hour passes slowly as the traffic control system guides his Type 921 down to a rocky rendezvous. Orange dust streaks his one optical-glass porthole: A kilometer before touchdown, Sadeq busies himself closing protective covers, locking down anything that might fall around on contact. Finally, he unrolls his mat against the floor in front of the console and floats above it for ten minutes, eyes closed in prayer. It's not the landing that worries him, but what comes next.

Her Majesty's domain stretches out before the battered module like a rust-stained snowflake half a kilometer in diameter. Its core is buried in a loose snowball of grayish rubble, and it waves languid brittlestar arms at the gibbous orange horizon of Jupiter. Fine hairs, fractally branching down to the molecular level, split off the main collector arms at regular intervals. A cluster of habitat pods like seedless grapes cling to the roots of the massive structure. Already he can see the huge steel generator loops that climb from either pole of the snowflake, wreathed in sparking plasma; the Jovian rings form a rainbow of darkness rising behind them.

At last, the battered space station is on final approach. Sadeq watches the Kurs simulation output carefully, piping it directly into his visual field. There's an external camera view of the rockpile and grapes. As the view expands toward the convex ceiling of the ship, he licks his lips, ready to hit the manual override and go around again – but the rate of descent is slowing, and by the time he's close enough to see the scratches on the shiny metal docking cone ahead of the ship, it's measured in centimeters per second. There's a gentle bump, then a shudder, then a rippling bang as the latches on the docking ring fire – and he's down.

Sadeq breathes deeply again, then tries to stand. There's gravity here, but not much: Walking is impossible. He's about to head for the life-support panel when he freezes, hearing a noise from the far end of the docking node. Turning, he's just in time to see the hatch opening toward him, a puff of vapor condensing, and then —

Her Imperial Majesty is sitting in the throne room, moodily fidgeting with the new signet ring her equerry has designed for her. It's a lump of structured carbon massing almost fifty grams, set in a plain band of asteroid-mined iridium. It glitters with the blue-and-violet speckle highlights of its internal lasers, because, in addition to being a piece of state jewelry, it is also an optical router, part of the industrial control infrastructure she's building out here on the edge of the solar system. Her Majesty wears plain black combat pants and sweatshirt, woven from the finest spider silk and spun glass, but her feet are bare: Her taste in fashion is best described as youthful, and in any event, certain styles are simply impractical in microgravity. But, being a monarch, she's wearing a crown. And there's a cat, or an artificial entity that dreams it's a cat, sleeping on the back of her throne.

The lady-in-waiting (and sometime hydroponic engineer) ushers Sadeq to the doorway, then floats back. "If you need anything, please say," she says shyly, then ducks and rolls away. Sadeq approaches the throne, orients himself on the floor (a simple slab of black composite, save for the throne growing from its center like an exotic flower), and waits to be noticed.

"Dr. Khurasani, I presume." She smiles at him, neither the innocent grin of a child nor the knowing smirk of an adult: merely a warm greeting. "Welcome to my kingdom. Please feel free to make use of any necessary support services here, and I wish you a very pleasant stay."

Sadeq holds his expression still. The queen is young – her face still retains the puppy fat of childhood, emphasized by microgravity moon-face – but it would be a bad mistake to consider her immature. "I am grateful for Your Majesty's forbearance," he murmurs, formulaic. Behind her the walls glitter like diamonds, a glowing kaleidoscope vision. It's already the biggest offshore – or off-planet – data haven in human space. Her crown, more like a compact helm that covers the top and rear of her head, also glitters and throws off diffraction rainbows; but most of its emissions are in the near ultraviolet, invisible except for the faint glowing nimbus it creates around her head. Like a halo.

"Have a seat," she offers, gesturing: A ballooning free-fall cradle squirts down and expands from the ceiling, angled toward her, open and waiting. "You must be tired. Working a ship all by yourself is exhausting." She frowns ruefully, as if remembering. "Two years is nearly unprecedented."

"Your Majesty is too kind." Sadeq wraps the cradle arms around himself and faces her. "Your labors have been fruitful, I trust."

She shrugs. "I sell the biggest commodity in short supply on any frontier …" A momentary grin. "This isn't the Wild West, is it?"

"Justice cannot be sold," Sadeq says stiffly. Then, a moment later: "My apologies, I mean no insult. I merely believe that, while you say your goal is to provide the rule of law, what you sell is and must be something different. Justice without God, sold to the highest bidder, is not justice."

The queen nods. "Leaving aside the mention of God, I agree – I can't sell it. But I can sell participation in a just system. And this new frontier really is a lot smaller than anyone expected, isn't it? Our bodies may take months to travel between worlds, but our disputes and arguments take seconds or minutes. As long as everybody agrees to abide by my arbitration, physical enforcement can wait until they're close enough to touch. And everybody does agree that my legal framework is easier to comply with, better adjusted to trans-Jovian space, than any earthbound one." A note of steel creeps into her voice, challenging: Her halo brightens, tickling a reactive glow from the walls of the throne room.

Five billion inputs or more , Sadeq marvels. The crown is an engineering marvel, even though most of its mass is buried in the walls and floor of this huge construct. "There is law revealed by the Prophet, peace be unto him, and there is law that we can establish by analysing his intentions. There are other forms of law by which humans live, and various interpretations of the law of God even among those who study His works. How, in the absence of the word of the Prophet, can you provide a moral compass?"

"Hmm." She taps her fingers on the arm of her throne, and Sadeq's heart freezes. He's heard the stories from the claim jumpers and boardroom bandits, from the greenmail experts with their roots in the earthbound jurisdictions that have made such a hash of arbitration here. How she can experience a year in a minute, rip your memories out through your cortical implants, and make you relive your worst mistakes in her nightmarishly powerful simulation space. She is the queen – the first individual to get her hands on so much mass and energy that she could pull ahead of the curve of binding technology, and the first to set up her own jurisdiction and rule certain experiments to be legal so that she could make use of the mass/energy intersection. She has force majeure – even the Pentagon's infowarriors respect the Ring Imperium's autonomy for now. In fact, the body sitting in the throne opposite him probably contains only a fraction of her identity. She's by no means the first upload or partial, but she's the first gust front of the storm of power that will arrive when the arrogant ones achieve their goal of dismantling the planets and turning dumb and uninhabited mass into brainpower throughout the observable reaches of the universe. And he's just questioned the rectitude of her vision, in her presence.
