If one could run without getting tired, I don't think one would often want to do anything else. But there might be special reasons for stopping, and it was a special reason which made Eustace presently shout:
"I say! Steady! Look what we're coming to!"
And well he might. For now they saw before them Caldron Pool and beyond the Pool the high unclimbable cliffs and, pouring down the cliffs, thousands of tons of water every second, flashing like diamonds in some places and dark, glassy green in others, the Great Waterfall; and already the thunder of it was in their ears.
"Don't stop! Further up and further in," called Farsight, tilting his flight a little upward.
"It's all very well for him," said Eustace, but Jewel also cried out:
"Don't stop. Further up and further in! Take it in your stride."
His voice could only just be heard above the roar of the water but next moment everyone saw that he had plunged into the Pool. And helter-skelter behind him, with splash after splash, all the others did the same. The water was not bitingly cold as all of them (and especially Puzzle) expected, but of a delicious foamy coolness. They all found they were swimming straight for the Waterfall itself.
"This is absolutely crazy," said Eustace to Edmund.
"I know. And yet --" said Edmund.
"Isn't it wonderful?" said Lucy. "Have you noticed one can't feel afraid, even if one wants to? Try it."
"By Jove, neither one can," said Eustace after he had tried.
Jewel reached the foot of the waterfall first, but Tirian was only just behind him. Jill was last, so she could see the whole thing better than the others. She saw something white moving steadily up the face of the Waterfall. That white thing was the Unicorn. You couldn't tell whether he was swimming or climbing, but he moved on, higher and higher. The point of his horn divided the water just above his head, and it cascaded out in two rainbow-colored streams all round his shoulders. Just behind him came King Tirian. He moved his legs and arms as if he were swimming, but he moved straight upward: as if one could swim up the wall of a house.
What looked funniest was the Dogs. During the gallop they had not been at all out of breath, but now, as they swarmed and wriggled upwards, there was plenty of spluttering and sneezing among them; that was because they would keep on barking, and every time they barked they got their mouths and noses full of water. But before Jill had time to notice all these things fully, she was going up the Waterfall herself. It was the sort of thing that would have been quite impossible in our world. Even if you hadn't drowned, you would have been smashed to pieces by the terrible weight of water against the countless jags of rock. But in that world you could do it. You went on, up and up, with all kinds of reflected lights flashing at you from the water and all manner of colored stones flashing through it, till it seemed as if you were climbing up light itself--and always higher and higher till the sense of height would have terrified you if you could be terrified, but later it was only gloriously exciting. And then at last one came to the lovely, smooth green curve in which the water poured over the top and found that one was on the level river above the Waterfall. The current was racing away behind you, but you were such a wonderful swimmer that you could make headway against it. Soon they were all on the bank, dripping but happy.
From The Last Battle by CS Lewis
"I was the lion." And as Shasta gaped with open mouth and said nothing, the Voice continued. "I was the lion who forced you to join with Aravis. I was the cat who comforted you among the houses of the dead. I was the lion who drove the jackals from you while you slept. I was the lion who gave the Horses the new strength of fear for the last mile so you could reach King Lune in time. And I was the lion you do not remember who pushed the boat in which you lay, a child near death, so that it came to shore where a man sat, wakeful at midnight, to receive you."
...
He turned and saw, pacing beside him, taller than the horse, a Lion. The horse did not seem to be afraid of it or else could not see it. It was from the Lion that the light came. No one ever saw anything more terrible or beautiful.
Luckily Shasta had lived all his life too far south in Calormen to have heard the tales that were whispered in Tashbaan about a dreadful Narnian demon that appeared in the form of a lion. And of course he knew none of the true stories about Aslan, the great Lion, the son of the Emperor-over-the-sea, the King above all High Kings in Narnia. But after one glance at the Lion's face he slipped out of the saddle and fell at its feet. He couldn't say anything but then he didn't want to say anything, and he knew he needn't say anything.
The High King above all kings stooped toward him. Its mane, and some strange and solemn perfume that hung about the mane, was all around him. It touched his forehead with its tongue. He lifted his face and their eyes met. Then instantly the pale brightness of the mist and the fiery brightness of the Lion rolled themselves together into a swirling glory and gathered themselves up and disappeared. He was alone with a horse on a grassy hillside under a blue sky. And there were birds singing.
