The Ringworld Throne

“No. Sailing Folk and Fishers.”

One Weaver of middle age was tending the pit with the help of seven aliens. They weren’t all of the same species. Two males had webbed hands and broad flat feet, and oily straight hair slicked along their bodies in a smooth curve. The other five, three men and two women, were burly, powerful versions of the Weavers, with altered jaws. Close enough that they might still mate, maybe. All seven were wearing the fantastic Weaver kilts.

The big Fisher, Shans Serpentstrangler, made introduction. Louis tried to remember their names. His translator would retrieve them, if he could remember even a syllable. Shans explained, “We trade for cloth, yes? We compete. When Hishthare Rockdiver and I offer to broil this monster fish the Sailors catch downstream, the Sailors offer, too. Afraid we talk to Kidada, learn something needful. Get a lower price.”

“Meanwhile we argue over how to cook our fish.” That was the Sailor, Wheek. “Kidada at least gets his birds the way he wants.”

“I’d say those birds are done,” Louis said. “I can’t guess about the fish. When did you start?”

“It will be perfect in a hundred breaths,” Shans said. “Cooked on the down side for the Sailors, warm on the up side for us. How do you like it?”

“Down side.”

The Weaver population half dried themselves and came to eat. The birds came off the hot rocks and were torn apart. The fish continued to cook. Louis would find his own vegetables, tomorrow.

And they talked.

The Weavers’ nimble fingers wove nets to catch mid-sized birds and beasts of the forest; but they wove cloth for river traffic. Peekaboo clothing, hammocks, fishnets, belt pouches and back pouches, a variety of things for a variety of species.

Fishers and Sailors traded up and down the river, carrying Weaver kilts, smoked and salted fish, salt, root vegetables …

It was shop talk. Louis eased out of that. He asked Kidada about his scar, and was told of a fight with what sounded like a monster bear. Weavers withdrew: they’d heard the tale. Kidada told a good tale, though from the sound of it, the scar should have been in front.

At sunset all the Weavers seemed to melt away. Sawur led him to a ring of tents, their feet crunching in dry brush.

Sailors and Fishers remained in conversation around the dying coal bed. One called advice after him: “Don’t wander. Only the Night People walk these paths at night.”

They stooped under the edge of the wicker cage. Sawur rolled against him and fell asleep at once. Louis felt a moment’s irritation; but species differ.

Sleeping in a strange place hadn’t bothered Louis in falans … no, in years. Nor sleeping in a strange woman’s arms, nor rubbing against fluffy fur … like sleeping with a big dog … nor both together. But knowing the Hindmost’s eye was near, that kept him awake for some time.

Sometime in the night, he dreamed that a monster sank teeth into his leg. He woke holding back a scream.

Sawur spoke without opening her eyes. “What is it, teacher?”

“Cramp. In my leg.” Louis rolled out of her arms and crawled to the door.

“I get cramps, too. Walk.” Sawur was asleep.

He limped outside. The side of his calf was shrieking. He hated muscle cramps!

The daylit arcs of the Ringworld reflected far more light than Earth’s full moon. The medical kit would give him medicine for a cramp, but it didn’t act any quicker than just walking it off.

His foot crunched dry twigs.

Low dry brush surrounded the guests’ huts. Friendly as they were, the Weavers must have some way to discourage thieves. This dry stuff might be their defense.

The cramp had eased, but he was wide-awake. His cargo plates floated outside the guest hut. He pulled himself aboard. He crossed the brushy barrier without a sound, weaving among the tree trunks.

Not a bit nocturnal, these Weavers. No sign of any of them. Sleeping like the dead, how would they catch a thief? The visiting aliens had retired, too. Lanterns lit the bow and stern of a long, low sailboat he hadn’t noticed earlier.

In a minute or two Louis was floating silently above the pool, lit by Archlight real and reflected.

Motion within the cliff … and a light blazed in his face.

Louis squinted, cursing. He looked into the glare … through a window with fuzzed-out edges, at an impressive cinder cone capped in what seemed dirty snow. On any world, that would be a volcano. Here it could be a meteor crater punched from below. It looked very like Fist-of-God, crowned with vacuum and naked Ringworld floor structure.

A message from the Hindmost?

Once the puppeteer knew Louis was moving up the river, he could have moved his probe ahead. He’d sprayed a spy device on this rock cliff, and others elsewhere, no doubt. He’d talked to the Weavers … easy enough, but why bother? What did he want?

Something spat from the crater, twice, thrice within ten seconds.

“Six hundred and ten hours ago,” said a familiar contralto. “Watch.”

The view zoomed on the three objects. Lens-shaped spacecraft, big. Kzinti design, Louis thought. They stopped just above the peak, then began their descent, two or three meters above the glassy crater wall.

“The warcraft are moving quite slowly. Let me show you fast-forward,” the Hindmost said. The warcraft moved briskly downslope. Beyond and below, cloudscape jumped into streamlined motion. “In two hours, twenty minutes at just under sonic speed, they had covered fourteen hundred miles. For kzinti, amazing restraint. Then they diverged, thus—”

The cloudscape and the saucers jerked to a near stop. Two veered off at right angles; the third continued straight on.

White light blinked. Then the scene was as before, but the three ships had a blobby, half-melted look, and they gleamed like mirrors. They began to descend … to fall.

“Stasis fields. They stopped your beam,” Louis said.

“Worrisome, Louis. Wrong twice within five seconds. Is your brain deteriorating?”

“That can happen,” Louis said equably.

The Hindmost said, “Those beams were intense. Vast energy flux was trapped inside the stasis fields before they formed.”

“But—”

“You and Nessus survived a similar attack because we design defense mechanisms to react quickly! Those kzinti warcraft are nothing but bombs now. And that was the Ringworld Meteor Defense, but I did not use it.”

“Yeah, right.”

“Observe.” The view jumped … a view of the magnified sun, darkened to something tolerable. From the fluid storm a plume rose in fast-forward motion. Higher, straight toward the camera … hundreds of thousands of miles. A brighter shock wave was rising from its base. It lashed out along the plume and was suddenly terribly bright.

“A superthermal laser effect, definitely the Ringworld Meteor Defense, Louis. But not mine.”

The Hindmost would lie. But would he shoot down an invading ship?

“Louis, I’m not shooting down invading spacecraft! I want to contact them. A hyperdrive motor could free me from this place!”

“I buy that, I guess, but—Hindmost, do you think someone is in the Repair Center with you?”

“I do not believe my defenses have been breached. Louis, there are two Great Oceans.”

It took Louis a moment to see what the Hindmost meant.

A single Great Ocean would unbalance the Ringworld. The water involved would mass as much as a major Jovian moon. There had to be two, on opposite arcs; and there were.

The Hindmost’s crew had found a Repair Center in one Great Ocean, under the Map of Mars. The other ocean they had never explored at all.

And it was across the Ringworld’s diameter. The Ringworld was sixteen light-minutes across. Sixteen minutes at lightspeed before a second Repair Center could see invading ships coming through Fist-of-God. Eight minutes more to begin to affect the sun. More time—an hour? Two?—to stretch a plume of plasma some millions of miles out from the sun, then cause it to lase. The terrible sword of light would be another eight minutes on its way.
