"You could populate it. There is room for a good-sized sun."

"You see, Jagged," explained the Duke of Queens, "our power-rings do not work. It suggests that the city cannot give us the energy we require."

"You have tried?"

"We have."

"Not two hours since," said Amelia Underwood.

"While the city was in flux. But now?"

"They will not work, Lord Jagged." Lord Mongrove stroked the dark stones on his fingers. "Our inheritance is spent forever."

"Oh, you are too doleful, all of you. It is merely a question of attitude." Lord Jagged stretched his left hand out before him and with his right he began to twist a ruby, staring into the sky the while, still half-conscious of his audience.

Overhead there appeared what might have been a small, twinkling star; but it was already growing. It became a fiery comet, turning the stark landscape jet black and glaring white. It grew again and it was a sun illuminating the featureless world for as far as their wincing eyes could see.

"That will do, I think." Jagged was quietly satisfied. "The conventional orbit." Another touch of the same ring. "And a turning world."

Amelia murmured: "You are the Master Conjuror, dear Lord Jagged. A veritable Mephistopheles. Is that sun the size of the old one?"

"A trifle smaller, but it is all we need."

"Skree," said Yusharisp in alarm, all his eyes slitted to resist the glare. "Skree, skree, skree!"

Jagged chose to take the remark as a compliment. "Just a simple beginning or two," he murmured modestly. He swirled the great yellow cloak about him. He touched another ring and the glare became less blinding, diffused as it was, now, by the shimmering atmosphere existing everywhere beyond the city. The sky became a greenish blue and the white landscape, with its deep, black fissures, became a dull grey, seamed with brown cracks; yet still it stretched to every horizon.

"How unsightly is our Earth without its images." The Iron Orchid was disdainful.

As if apologizing for it, Jagged said: "It is a very old planet, my dear. But you must all regard it as a new canvas. Everything you wish for can be re-created. New scenes can be created, just as it has always been. Rest assured that the cities will not fail us."

"So Judgement Day is resisted, after all." The time-traveller had his head on one side as he looked, with new eyes, at Lord Jagged of Canaria. "I congratulate you, sir. You command enormous power, it seems."

"I borrow the power," said Jagged, to him, his voice soft. "It comes from the cities."

CPS Shushurup cried: "It cannot be real! This man confounds us with an illusion (skree)!"

Lord Jagged affected not to hear him and turned, instead, to Mrs. Persson who watched him, her expression analytical. "The cities conserved their energies because I need them for what, I am confident, will be a successful experiment. Of course, not everyone will consider my plan a perfect one, but it is a beginning. It is what I mentioned to you, Mrs. Persson."

"It is why we are here." Her smile was for Captain Bastable. "To see if it should work. Certainly I am convinced by the preliminaries."

The huge and healthy sun shone down on them all, its light spreading through the city, casting great, mellow shadows. The city continued to throb quietly and steadily; an engine waiting to be used.

"It's extremely impressive, sir," said Bastable. "When do you intend to make the loop?"

"In about a month."

"You cannot," said Mrs. Persson, "sustain this state indefinitely?"

"It would be preferable, of course, but uneconomic."

They shared amusement.

CPS Shushurup waddled up, waving a leg. "Do not let (skree) yourselves be (roar) convinced by this (skree) illusion. For (roar) illusion is all that it is!"

Lord Jagged said mildly: "It depends, does it not, upon your interpretation of the word 'illusion'? It is a warming sun, a breathable atmosphere, the planet turns on its orbit, it circles that sun."

Yusharisp joined the Chief Public Servant. The bright sunlight emphasized the warts and blotches on his little round body. "It is illusion (skree), Lord Jagged, because (roar) it cannot last the (yelp) disintegration (skree) of the universe!"

"I think it will, Mr. Yusharisp." Lord Jagged made to address his son, but the Pweelians refused to content themselves with his answer.

"Energy (skree) is needed to produce (roar) such 'miracles' — you will (skree) agree to that?"

Lord Jagged inclined his head.

"There must (roar) therefore be a source (skree) — perhaps a planet (skree) or two which (yelp) have escaped the (skree) catastrophe. That source (roar) will he used up soon (yelp) enough!"

It seemed that Lord Jagged of Canaria spoke to everyone but his questioner. He retained the same mild, but slightly icy, expression. "I fear that you cannot draw satisfaction even from that idea, my dear Yusharisp. Morals may be drawn, but by a more liberal intelligence."

"Morals (skree)! You know (roar) nothing of such (yelp) things!"

Lord Jagged continued to speak to them all, now more directly than before. "Such is the character of one prone to morbid anxiety that he would rather experience the worst of things than hope for the best. It is a particular and puritanical mentality, and one to which I can respond with scant sympathy. Why have such conclusions been drawn? Because that kind of mentality would prefer to bring on catastrophe rather than live forever in fear of its possibility . Suicide rather than uncertainty."

"You are not (roar) suggesting that (skree) this problem was merely (yelp) in our own (skree) minds, Lord Jagged?" Again the strange, mechanical laughter from CPS Shushurup.

"Was it not the people of Pweeli who took it upon themselves to spread the bad news throughout the galaxy? Did you not preach your despair wherever you could find hearers? The facts were plain enough to all, but your response to them was scarcely positive. Therefore, yes — to some degree the problem was merely in your own minds. You have not investigated all the possibilities. Your case depends, for one thing, upon a firm belief in a finite universe, with finite resources. However, as the time-traveller here will tell you and as Mrs. Persson and Captain Bastable will confirm, the universe is not finite."

"Words (skree) and nothing more…"

The time-traveller spoke earnestly. "I may not agree with Lord Jagged in most things, but he speaks the truth. There are a multiplicity of dimensions to the universe which you, Mrs. Persson, refer to I believe as 'the multiverse'. This is merely one such dimension, although, indeed, all experience the same fate as this one, but not simultaneously."

Lord Jagged acknowledged the time-traveller's support. "Therefore, by drawing its resources from any part of the multiverse at any point in time — which will not be a parallel point — this planet can be sustained forever, if need be."

"The notion (yelp) is quite without foundation," said Yusharisp dismissively.

Lord Jagged drew his high collar about his face and stretched an elegant hand towards the sun. "There is my proof, gentlemen."

"Illusion," said Yusharisp obstinately, "(yelp)."

"Pseudo-science (skree)," agreed Shushurup.

Lord Jagged made an acquiescent gesture and would respond no more, but Mrs. Persson remained sympathetic to the aliens in their great distress. "We have discovered," she said gently, "that the 'real' universe is infinite. Infinite, timeless and still. It is a tranquil pool which will reflect any image we conceive."

"Meta(skree)physical poppy(roar)cock!"

Captain Bastable came to her aid. "It is we who populate the universe with what we call Time and Matter. Our intelligence moulds it; our activities give it detail. If, sometimes, we imprison ourselves, it is perhaps because our humanity is at fault, or our logic…"
