<h3>Lair of Mano-Nui</h3>
<p>Just under the surface of the water the sea was warm, weird life showed
colors Ross could name, shades he could not. The corals, the animals
masquerading as plants, the plants disguised as animals which inhabited
the oceans of Terra, had their counterparts here. And the settlers had
given them the familiar names, though the crabs, the fish, the anemones,
and weeds of the shallow lagoons and reefs were not identical with
Terran creatures. The trouble was that there was too much, such a wealth
of life to attract the eyes, hold attention, that it was difficult to
keep to the job at hand—the search for what was not natural, for what
had no normal place here.</p>
<p>As the land seduced the senses and bewitched the off-worlder, so did the
sea have its enchantment to pull one from duty. Ross resolutely skimmed
by a forest of weaving, waving lace which varied from a green which was
almost black to a pale tint he could not truly identify. Among those
waving fans lurked ghost-fish, finned swimmers transparent enough so
that one could sight, through their pallid sides, the evidences of
recently ingested meals.</p>
<p>The Terrans had begun their sweep-search a half hour ago, slipping
overboard from a ferry canoe, heading in toward the checkpoint of the
finger isle, forming an arc of expert divers, men and girls so at home
in the ocean that they should be able to make the discovery Ashe
needed—if such did exist.</p>
<p>Mystery built upon mystery on Hawaika, Ross thought as he used his
spear-gun to push aside a floating banner of weed in order to peer below
its curtain. The native life of this world must always have been largely
aquatic. The settlers had discovered only a few small animals on the
islands. The largest of which was the burrower, a creature not unlike a
miniature monkey in that it had hind legs on which it walked erect and
forepaws, well clawed for digging purposes, which it used with as much
skill and dexterity as a man used hands. Its body was hairless and it
was able to assume, chameleon-like, the color of the soil and rocks
where it denned. The head was set directly on its bowed shoulders
without vestige of neck; and it had round bubbles of eyes near the top
of its skull, a nose which was a single vertical slit, and a wide mouth
fanged for crushing the shelled creatures on which it fed. All in all,
to Terran eyes, it was a vaguely repulsive creature, but as far as the
settlers had been able to discover it was the highest form of land life.
The smaller rodentlike things, the two species of wingless diving birds,
and an odd assortment of reptiles and amphibians sharing the island were
all the burrowers' prey.</p>
<p>A world of sea and islands, what type of native intelligent life had it
once supported? Or had this been only a galactic colony, with no native
population before the coming of the stellar explorers? Ross hovered
above a dark pocket where the bottom had suddenly dipped into a
saucer-shaped depression. The sea growth about the rim rippled in the
water raggedly, but there was something about its general outline....</p>
<p>Ross began a circumference of that hollow. Allowing for the distortion
of the growths which had formed lumpy excrescences or reached turrets
toward the surface—yes, allowing for those—this was decidedly
something out of the ordinary! The depression was too regular, too even,
Ross was certain of that. With a thrill of excitement he began a descent
into the cup, striving to trace signs which would prove his suspicion
correct.</p>
<p>How many years, centuries, had the slow coverage of the sea life
gathered there, flourished, died, with other creatures to build anew on
the remains? Now there was only a hint that the depression had other
than a natural beginning.</p>
<p>Anchoring with a one-handed grip on a spike of Hawaikan coral—smoother
than the Terran species—Ross aimed the butt of his spear-gun at the
nearest wall of the saucer, striving to reach into a crevice between two
lumps of growth and so probe into what might lie behind. The spear
rebounded; there was no breaking that crust with such a fragile tool.
But perhaps he would have better luck lower down.</p>
<p>The depression was deeper than he had first judged. Now the light which
existed in the shallows vanished. Red and yellow as colors went, but
Ross was aware of blues and greens in shades and tints which were not
visible above. He switched on his diving torch, and color returned
within its beam. A swirl of weed, pink in the light, became darkly
emerald beyond as if it possessed the chameleon ability of the
burrowers.</p>
<p>He was distracted by that phenomenon, and so he transgressed the diver's
rule of never becoming so absorbed in surroundings as to forget caution.
Just when did Ross become aware of that shadow below? Was it when a
school of ghost-fish burst unexpectedly between weed growths, and he
turned to follow them with the torch? Then the outer edge of his beam
caught the movement of a shape, a flutter in the water of the gloomy
depths.</p>
<p>Ross swung around, his back to the wall of the saucer, as he aimed the
torch down at what was arising there. The light caught and held for a
long moment of horror something which might have come out of the
nightmares of his own world. Afterward Ross knew that the monster was
not as large as it seemed in that endless minute of fear, perhaps no
bigger than the dolphins.</p>
<p>He had had training in shark-infested seas on Terra, been carefully
briefed against the danger from such hunters of the deep and ocean
jungles. But this kind of thing had only existed before in the fairy
tales of his race as the dragon of old lore. A scaled head with wide
eyes gleaming in the light beam with cold and sullen hate, a gaping
mouth fang-filled, a horn-set muzzle, that long, undulating neck and,
below it, the half-seen bulk of a monstrous body.</p>
<p>His spear-gun, the knife at his waist belt, neither were protection
against this! Yet to turn his back on that rising head was more than
Ross could do. He pulled himself back against the wall of the saucer.
The thing before him did not rush to attack. Plainly it had seen him and
now it moved with the leisure of a hunter having no fears concerning the
eventual outcome of the hunt. But the light appeared to puzzle it and
Ross kept the beam shining straight into those evil eyes.</p>
<p>The shock of the encounter was wearing off; now Ross edged his flipper
into a crevice to hold him steady while his hand went to the sonic-com
at his waist. He tapped out a distress call which the dolphins could
relay to the swimmers. The swaying dragon head paused, held rigid on a
stiff, scaled column in the center of the saucer. That sonic vibration
either surprised or bothered the hunter, made it wary.</p>
<p>Ross tapped again. The belief that if he tried to escape, he was lost,
that only while he faced it so had he any chance, grew stronger. The
head was only inches below the level of his flippered feet as he held to
the weeds.</p>
<p>Again that weaving movement, the rise of head, a tremor along the
serpent neck, an agitation in the depths. The dragon was on the move
again. Ross aimed the light directly at the head. The scales, as far as
he could determine, were not horny plates but lapped, silvery ovals such
as a fish possessed. And the underparts of the monster might even be
vulnerable to his spear. But knowing the way a Terran shark could absorb
the darts of that weapon and survive, Ross feared to attack except as a
last resort.</p>
<p>Above and to his left there was a small hollow where in the past some
portion of the growths had been ripped away. If he could fit himself
into that crevice, perhaps he could keep the dragon at bay until help
arrived. Ross moved with all the skill he had. His hand closed upon the
edge of the niche and he whirled himself up, just making it into that
refuge as the head lashed at him wickedly. His suspicion that the dragon
would attack anything on the run was well founded, and he knew he had no
hope of winning to the surface above.</p>
<p>Now he stood in the crevice, facing outward, watching the head darting
in the water. He had switched off the torch, and the loss of light
appeared to bewilder the reptile for some precious seconds. Ross pulled
as far back into the niche as he could, until the point of one shoulder
touched a surface which was sleek, smooth, and cold. The shock of that
contact almost sent him hurtling out again.</p>
<p>Gripping the spear before him in his right hand, Ross cautiously felt
behind him with the left. His finger tips glided over a seamless surface
where the growths had been torn or peeled away. Though he could not, or
dared not, turn his head to see, he was certain that this was his proof
that the walls of the saucer had been fashioned and placed there by some
intelligent creature.</p>
<p>The dragon had risen, hovering now in the water directly before the
entrance to Ross's hole, its neck curled back against its bulk. It had
wide flippers moving like planes to hold it poised. The body, sloping
from a massive round of shoulders to a tapering rear, was vaguely
familiar. If one provided a Terran seal with a gorgon head and scales in
place of fur, the effect would be similar. But Ross was assuredly not
facing a seal at this moment.</p>
<p>Slight movement of the flippers kept it as stabilized as if it sprawled
on a supporting surface. With the neck flattened against the body, the
head curved downward until the horn on its snout pointed the tip
straight at Ross's middle. The Terran steadied his spear-gun. The
dragon's eyes were its most vulnerable targets; if the creature launched
the attack, Ross would aim for them.</p>
<p>Both man and dragon were so intent upon their duel that neither was
conscious of the sudden swirl overhead. A sleek dark shape struck down,
skimming across the humped-back ridge of the dragon. Some of the
settlers had empathy with the dolphins to a high degree, but Ross's own
powers of contact were relatively feeble.</p>
<p>Only now he was given an assurance of aid, and a suggestion to attack.
The dragon head writhed, twisted as the reptile attempted to see above
and behind its own length. But the dolphin was only a streak fast
disappearing. And that writhing changed the balance the monster had
maintained, pushing it toward Ross.</p>
<p>The Terran fired too soon and without proper aim, so the dart snaked
past the head. But the harpoon line half hooked about the neck and
seemed to confuse the creature. Ross squirmed as far back as he could
into his refuge and drew his knife. Against those fangs the weapon was
an almost useless toy, but it was all he had.</p>
<p>Again the dolphin dived in attack on the reptile, this time seizing in
its mouth the floating cord of the harpoon and giving it a jerk which
jolted the dragon even more off balance, pulling it away from Ross's
niche and out into the center of the saucer.</p>
<p>There were two dolphins in action now, Ross saw, playing the dragon as
matadors might play a bull, keeping the creature disturbed by their
agile maneuvers. Whatever prey came naturally to the Hawaikan monster
was not of this type, and the creature was not prepared to deal
effectively with their teasing, dodging tactics. Neither had touched the
beast, but they kept it constantly striving to get at them.</p>
<p>Though it swam in circles attempting to face its teasers, the dragon did
not abandon the level before Ross's refuge, and now and then it darted
its head at him, unwilling to give up its prey. Only one of the dolphins
frisked and dodged above now as the sonic on Ross's belt vibrated
against his lower ribs with its message warning to be prepared for
further action. Somewhere above, his own kind gathered. Hurriedly he
tapped out in code his warning in return.</p>
<p>Two dolphins busy again, their last dive over the dragon pushing the
monster down past Ross's niche toward the saucer's depths. Then they
flashed up and away. The dragon was rising in turn, but coming to meet
the Hawaikan creature was a ball giving off light, bringing sharp vision
and color with it.</p>
<p>Ross's arm swung up to shield his eyes. There was a flash; such
answering vibration carried through the waves that even his nerves, far
less sensitive than those of the life about him, reacted. He blinked
behind his mask. A fish floated by, spiraling up, its belly exposed. And
about him growths drooped, trailed lifelessly through the water; while
there was a now motionless bulk sinking to the obscurity of the
depression floor. A weapon perfected on Terra to use against sharks and
barracuda had worked here to kill what could have been more formidable
prey.</p>
<p>The Terran wriggled out of the niche, rose to meet another swimmer. As
Ashe descended, Ross relayed his news via the sonic. The dolphins were
already nosing into the depths in pursuit of their late enemy.</p>
<p>"Look here—" Ross guided Ashe to the crevice which had saved him, aimed
the torch beam into it. He had been right! There was a long groove in
the covering built up by the growths; a vertical strip some six feet
long, of a uniform gray, showed. Ashe touched the find and then gave the
alert via the sonic code.</p>
<p>"Metal or an alloy, we've found it!"</p>
<p>But what did they have? Even after an hour's exploration by the full
company, Ashe's expert search with his knowledge of artifacts and
ancient remains, they were still baffled. It would require labor and
tools they did not have, to clear the whole of the saucer. They could be
sure only of its size and shape, and the fact that its walls were of an
unknown substance which the sea could cloak but not erode. For the
length of gray surface showed not the slightest pitting or time wear.</p>
<p>Down at its centermost point they found the dragon's den, an arch coated
with growth, before which sprawled the body of the creature. That was
dragged aloft with the dolphins' aid, to be taken ashore for study. But
the arch itself ... was that part of some old installation?</p>
<p>Torches to the fore, they entered its shadow, only to remain baffled.
Here and there were patches of the same gray showing in its interior.
Ashe dug the butt of his spear-gun into the sand on the flooring to
uncover another oval depression. But what it all signified or what had
been its purpose, they could not guess.</p>
<p>"Set up the peep-probe here?" Ross asked.</p>
<p>Ashe's head moved in a slow negative. "Look farther ... spread out," the
sonic clicked.</p>
<p>Within a matter of minutes the dolphins reported new remains—two more
saucers, each larger than the first, set in a line on the ocean floor,
pointing directly to Karara's Finger Island. Cautiously explored, these
were discovered to be free of any but harmless life; they stirred up no
more dragons.</p>
<p>When the Terrans came ashore on Finger Island to rest and eat their
midday meal one of the men paced along the beached dragon. Ashore it
lost none of its frightening aspect. And seeing it, even beached and
dead, Ross wondered at his luck in surviving the encounter without a
scratch.</p>
<p>"I think that this one would be alone," PaKeeKee commented. "Where there
is an eater of this size, there is usually only one."</p>
<p>"Mano-Nui!" The girl Taema shivered as she gave to this monster the name
of the shark demon of her people. "Such a one is truly king shark in
these waters! But why have we not sighted its like before? Tino-rau,
Taua ... they have not reported such—"</p>
<p>"Probably because, as PaKeeKee says, these things are rare," Ashe
returned. "A carnivore of size would have to have a fairly wide hunting
range, yet there's evidence that this thing has laired in that den for
some time. Which means that it must have a defined hunting territory
allowing no trespassing from others of its species."</p>
<p>Karara nodded. "Also it may hunt only at intervals, eat heavily, and lie
quiet until that meal is digested. There are large snakes on Terra that
follow that pattern. Ross was in its front yard when it came after
him—"</p>
<p>"From now on"—Ashe swallowed a quarter of fruit—"we know what to watch
for, and the weapon which will finish it off. Don't forget that!"</p>
<p>The delicate mechanisms of their sonics had already registered the
vibrations which would warn of a dragon's presence, and the depth globes
would then do the rest.</p>
<p>"Big skull, oversize for the body." PaKeeKee squatted on his heels by
the head lying on the sand at the end of the now fully extended neck.</p>
<p>Ross had heretofore been more aware of the armament of that head, the
fangs set in the powerful jaws, the horn on the snout. But PaKeeKee's
comment drew his attention to the fact that the scale-covered skull did
dome up above the eye pits in a way to suggest ample brain room. Had the
thing been intelligent? Karara put that into words:</p>
<p>"Rule One?" She went over to survey the carcass.</p>
<p>Ross resented her half question, whether it was addressed to him or mere
thinking aloud on her part.</p>
<p>Rule One: Conserve native life to the fullest extent. Humanoid form may
not be the only evidence of intelligence.</p>
<p>There were the dolphins to prove that point right on Terra. But did Rule
One mean that you had to let a monster nibble at you because it might
just be a high type of alien intelligence? Let Karara spout Rule One
while backed into a crevice under water with that horn stabbing at her
mid-section!</p>
<p>"Rule One does not mean to forego self-defense," Ashe commented mildly.
"This thing is a hunter, and you can't stop to apply recognition
techniques when you are being regarded as legitimate prey. If you are
the stronger, or an equal, yes—stop and think before becoming
aggressive. But in a situation like this—take no chances."</p>
<p>"Anyway, from now on," Karara pointed out, "it could be possible to
shock instead of kill."</p>
<p>"Gordon"—PaKeeKee swung around—"what have we found here—besides this
thing?"</p>
<p>"I can't even guess. Except that those depressions were made for a
purpose and have been there for a long time. Whether they were
originally in the water, or the land sank, that we don't know either.
But now we have a site to set up the peep-probe."</p>
<p>"We do that right away?" Ross wanted to know. Impatience bit at him. But
Ashe still had a trace of frown. He shook his head.</p>
<p>"Have to make sure of our site, very sure. I don't want to start any
chain reaction on the other side of the time wall."</p>
<p>And he was right, Ross was forced to admit, remembering what had
happened when the galactics had discovered the Red time gates and traced
them forward to their twentieth-century source, ruthlessly destroying
each station. The original colonists of Hawaika had been as giants to
Terran pygmies when it came to technical knowledge. To use even a
peep-probe indiscreetly near one of their outposts might bring swift and
terrible retribution.</p>
