During the next ten minutes, he saw several of these “water sprites,” and realized that, like the chameleon men, they seemed to be able to make themselves visible or invisible, or change their form at will. If he tried hard, he could see them after they disappeared, but by that time they had become transparent, as if made of glass.
Among the assorted folklore Niall had absorbed in the white tower was a knowledge of fairies and water sprites, but he had been taught that they were curious and quaint superstitions; now it was plain that they really existed.
A moment later an even odder thing happened. They were crossing a stream on a moss-encrusted log, and Niall stumbled forward into the chameleon man who was walking in front of him, and was afraid that he had knocked him into the stream. He was surprised when there was no impact, then astonished as he saw the legs of the chameleon man partly blended with his own. Far from objecting to this superimposition of Niall’s body on his own, the chameleon man seemed to enjoy it, and the care required to reach the other end of the log prolonged the contact for about ten seconds more, during which time Niall became aware that they were surrounded by tiny figures, none more than a foot high. There must have been a dozen or so in the stream and on its banks, mostly female, although a few appeared to be male, or of indeterminate sex. Moreover, on a carpet of fallen leaves among the trees on the far bank there were taller beings, perhaps two feet high, and who Niall at first took to be naked children, as well as some creatures resembling small brown animals.
All these vanished as soon as Niall stepped ashore and lost contact with the chameleon man. But now that he knew they were there, he made an effort to see them by staring hard at the shadows among the leaves. This at first had no effect. Then he tripped over a fallen branch, and as he did so, was suddenly able to see them again. Although they instantly vanished, he was now aware that looking too hard was counterproductive, and that he had to relax and use a kind of natural instinct. He later came to refer to it as “looking sideways.”
As soon as he did this, the figures reappeared, but he was intrigued to see that they were now fully clothed, wearing gray garments and green headgear that fitted tightly around the skull. This seemed so incongruous that he almost laughed. He was quite certain they had been naked when he first saw them.
Another collision with a chameleon man offered him a clue. Once again, it was his own fault — he was trying to look back over his shoulder when he tripped over a rock. This time he landed on all fours, and several chameleon men walked into him. As their bodies blended with his, the gray-clad figures suddenly became naked, looking like small, overweight men. By the time Niall stood up and wiped the damp earth off his hands on dry leaves, the figures had disappeared altogether. He made them reappear by “looking sideways”; but again they were clothed in gray garments.
But the trick of “looking sideways” had given him the clue. He had made them reappear by using his own mind. They had been there, but were invisible until he made the effort. But when he saw them through the eyes of the chameleon men, they were naked. Was it possible that he was somehow adding the clothes with his imagination?
There was, of course, another possibility — that the clothes were “added” by the little creatures themselves. Perhaps that was how they preferred a human being to see them.
All this had fascinating implications. The trees around him looked solid because he was sure they were really there, and sure they looked exactly as he thought they looked. But suppose his imagination also “added” something to their appearance, just as it seemed to “add” clothes to the little men?
It was a bewildering thought whose implications seemed endless. But Niall was in no condition for such speculations. This was one of the drawbacks of seeing the world in such dazzling colors; his brain was so flooded with impressions that it was difficult to think clearly. He found himself wishing that he had a pair of the dark spectacles that Simeon wore when the Sun was too bright.
Farther downstream, Niall caught a glimpse of the brown, furry creatures, and was amused to see that they looked like a parody of human beings. They walked upright on tiny legs, and carried their short arms — or forelegs — in front of them. Their faces emerged from a fringe of fur, and had bright, intelligent eyes, and a long nose like a hedgehog’s, ending in a flat point resembling a pig’s snout, which snuffled continuously. But when they saw Niall, then noticed the chameleon men, they hastily vanished among the trees. When Niall inquired why, he was told that they were mischievous and destructive beings, ruining young trees with their sharp teeth — not merely for food, but simply for the pleasure of using their teeth. Niall found it almost unbelievable that some of the creatures in this woodland paradise should be wantonly disruptive.
Soon after this he had an opportunity to observe that they they were not the only ones. Half a mile farther on, the stream widened into a brown pool that covered half an acre. There was obviously a blockage downstream. The chameleon men spread out among the trees, and asked Niall to fall back to their rear; they clearly blamed some living agency for this flood, and wanted to approach unseen.
On the far side of the pool, they found its cause: two dead trees that held back a conglomerate of leaves and black mud. From its far side came a high-pitched, chattering squeak that sounded like excited birds.
Quite suddenly, the chameleon men made themselves visible, and the chattering sounds turned into shrieks of alarm. About a dozen humanoid creatures fled in all directions, some of them diving straight over the dam — these latter rose into the air like enormous silver fish, then, once in the brown water, simply vanished.
For a moment, Niall had a hallucinatory sense of being back in the Delta, for the creatures resembled the frog men he had encountered there. But the similarity was only superficial. The frog men of the Delta were gray, with yellow carnivorous teeth, and they spat jets of venom. These creatures, who were about two feet high, looked almost human, except for their abnormally long arms and legs and their webbed hands and feet. They had pointed, foxlike faces, with a fringe of green hair and large bulbous eyes. They were silvery-green, with black markings. And they ran like humans, covering the ground at enormous speed with their spindly legs. In about ten seconds, all had vanished.
Niall was hypnotized by the sight of the waterfall created by the dead trees, for it flashed and sparkled in a way that could not be attributed entirely to reflected sunlight. After staring intently for several minutes, he had no doubt that the flowing stream released some form of energy, created by the sunlight, which was absorbed by the elemental who shimmered in and out of existence in the green water.
The chameleon men — now quite obviously solid — went on to dismantle the dam; after the logs had been removed, it collapsed with a gurgling roar, and the water thundered down the valley. Within minutes, the pool had been drained.
But why, Niall wanted to know, had these fish creatures wanted to block the stream?
The answer, it seemed, was: to make themselves a kind of swimming pool. These froglike beings never ceased to look around for some kind of mischief that would irritate the chameleon men and undo their work of creating harmony. Like the brown animals, they had a destructive streak. Niall thought of the bombardier beetles, with their love of explosions, and felt he could begin to understand.
Throughout most of the morning they continued to travel through an amazingly varied landscape of woodland, low hills, and winding streams. This was Niall’s first opportunity to see an October landscape, with its falling leaves and distinct autumn smell, and he found it almost painfully beautiful. Because of the heightening of his perceptions, it often seemed that the landscape was speaking to him, or that it had some deep significance it was trying to convey. And on at least two occasions he experienced a curious sense of familiarity, of having seen it before.
He also learned from the chameleon men that most trees had their own elemental spirit. One young oak made such an impression of radiant vitality that he stopped to stare at it. The leader of the chameleon men thereupon touched his elbow, causing an instant alteration in his perceptions which revealed that the trunk of the tree was surrounded by a dim green aura that extended about a foot beyond the bark, while the tree itself, which now seemed transparent, was of a deeper and more brilliant green. As he gazed into this core of vibrating energy, he suddenly realized that it contained a living shape, which vibrated at a different rate than the tree, and that he could make out a face. If he changed the focus of his gaze, the face disappeared, so that he was not certain whether it was real, or whether, like faces seen in the fire, it was the result of his imagination.
