The Ringworld Throne

“By no means.”

“What then, puppeteer experiments?”

“I’ve tried to describe what I have available, a modified ARM X-program.”

“You can’t compute the cost of this thing against fees payable at a Sol hospital! Your system would give me another thirty years of life, roughly speaking, wouldn’t it? I’ll give you seven years of service following my emergence from the ‘doc.”

“Twelve! Louis, this system will rewrite you to the age of twenty! You’d get another fifty years with no further medical treatment at all!”

“The risks you’ll put me through, I’ll be lucky to get fifty good days, and you know it. That’s why I went on sabbatical in the first place. Seven.”

“Stet.”

Louis pointed with his left forefinger, the cursor. {Time expended shall be computed only for discrete actions taken at the direction of the Hindmost.} “Now what is this flup? What about consultation time? Travel time? Actions done without consulting you because there’s no time? Subconscious problem-solving during sleep?”

“Write it in.”

“Your motives are questionable. No honest entity would have tried that.”

“This is how negotiation works, Louis.”

“You’re going to teach me how to negotiate? Stet.” Louis erased the offending sentence, then typed one- fingered on the air. {Service period shall terminate seven years after acceptance of this contract.} He ignored the squawk of distress. “Now I need a clause to protect me from being altered into a better servant. I don’t see anything in here that will do that.”

Text added itself. Louis watched for a bit, then said, “No.”

“Write, then.”

“No. Can you think of any way to get yourself a copy of my contract?”

“No.”

“It’ll have to wait for me to reach Hidden Patriarch, then. I’ll start tomorrow.”

“Wait! Louis, I can easily find you here.”

“Hindmost, I think I’ll have to insist on your accepting my contract, not yours. If you can’t read it, how can you suggest changes?”

“You must read it to me aloud.”

“Tomorrow. Now, something else has been bothering me. How long does it take you to shape a plume from the sun and then set off the superthermal laser effect?”

“Two hours, sometimes three. Conditions vary.”

“Three ships came through Fist-of-God, near here, and someone blasted them. One landed on the far side of the Ringworld and something blasted it. Did that take longer? What with all the fast- forward action, I just couldn’t tell.”

“I will look.”

Louis woke late. Sawur and the children were gone. Nothing edible remained from last night. Louis worked near the empty firepit.

{No entity or process shall alter Louis Wu’s patterns of thought by medical or chemical means nor by any means save persuasion worked while Louis Wu is fully conscious and in his right mind. No agreements made while he is not fully conscious and in his right mind shall be binding.}

{The period of servitude} — Louis crossed out “servitude.” — {mutual dependence shall end no more than seven years after acceptance of this contract. Wu shall be entitled to sleep, meals, and periods of healing as required. Emergencies interrupting these free times shall shorten the period of mutual dependence at triple time. Penalties for violations… vacation periods mutually agreed upon shall extend the period of mutual dependence… Louis Wu may refuse any command if in his sole judgment the commission involves undue risk, undue damage to local hominids or their culture or their environment, global damage to the Ringworld, or clear ethical violations.} A few talking points wouldn’t hurt.

He’d become ferociously hungry. He knew where to find more roots. Louis rode the cargo stack straight up to seek out a path, and saw children milling in the upland woods across the Shenthy River.

Sawur had found two big mushrooms of different species, and the children had killed a land-going crustacean as big as a rabbit. They watched with interest as Louis wrapped them in leaves and then wet clay. He dug his flash out of the lockbox on his cargo stack. With the flash on microwave, wide aperture, medium intensity, he heated the mound of clay until it puffed steam. Then he carefully locked the flash away. A dangerous thing to leave loose.

“Strill, Parald, keep the rest away from the clay. It’ll burn you. Sawur? I want to make you a parting gift.”

“Louis, are we to part?”

“The Web Dweller sent his refueling probe to spray the cliff. It must be nearby. I expect he could have it here in a few hours.” He hopped off the plates. “Let me show you this now. I’m wondering if it should go to you or to the whole village.”

The cargo plate controls were depressions on the rims, and they took some strength to move. Protector strength. Louis jabbed with a slender piece of rod held in both hands. The bottommost plate dropped from his stack and floated an inch above the grass.

Sawur asked, “Will you present it tonight? Give it to the village in charge of me and Kidada. I will be as surprised as any. Show him and me how to work it, but none other, and no visitors.”

“Stet.”

“This is a magnificent gift, Louis.”

“Sawur, you’ve given me my life. I think. Maybe.”

“Do you still doubt?”

“Give me a moment.” Louis knocked the clay off one end of his mound. The mushrooms looked and smelled done.

They tasted wonderful. He broke open the rest of the mound and found the crawler done, too. Most of the meat was in the spinnerets, and the children shared those around. The tail made one bite each for him and Sawur.

“That’s better. I’m not rational when I’m that hungry. Now look.” Louis drew a ring in the dirt. “Light takes thirty-two minutes to cross the Ringworld and come back.” He heard the translator converting times and distances.

“Really?”

“Trust me. Eight minutes for a beam from the sun to touch the Arch. Sixteen minutes across, thirty-two to cross and come back. If three starships pop up through a hole here, near the Great Ocean, and two and a half hours later they’re destroyed, and a ship lands here and is destroyed two hours later, where is the attacker?”

Sawur studied the sketch, then pointed. “Here, across the Arch. The first ships, he needed half an hour just to see them.”

“But what if it is attacked three hours later?”

Sawur said, “That would put the attacker here where you drew the Great Ocean.”

“Yeah.”

When shadow touched the sun, Louis had written a contract that ought to protect him, if a puppeteer would honor a contract.

He presented the cargo plate to Weaver Town while dinner was broiling. They acclaimed him as a mighty magician, a vashnesht. Then children wanted to ride the plate while parents were urging caution. Louis showed Kidada the setting that would hold the disk two feet high, low enough to be safe.

He watched Kidada swooping among the houses with Strill whooping in his arms, and hoped that they wouldn’t burn the thing out joyriding. One day they’d need it to lift something heavy.

The light was disappearing. Hunters had killed a predator; the meat tasted too much of cat. Weavers took slices and settled to watch the cliff as it came alight. Perched on his stack of cargo plates like a proper wizard,
