"Wait until you see me wave," he said. ulf you throw it before I'm ready, I'll have to dive for it, and the lo-cathah might catch up."
"I'll wait." Kani kissed him, then turned to wade ashore. "Remember your promise."
"I remember."
Tanetoa waded into the lagoon, then swam back to the channel, where the locathah were continuing to arrive from the open sea. As he left the passage, several of the creatures stopped below him, and one waved its thin arms in greeting.
"Hail, Reefmaster. Do you go to the humans?"
Tanetoa dived under the water, where the conversation would be hidden from human eyes. "I do." Tanetoa could not tell whether he was speaking with the same locathah as earlier, for they all looked the same to him. "I go to make them leave."
"How can you do that? Humans are stupid creatures who never listen to reason."
"Nothing is truer," agreed Tanetoa, "but I am a giant."
"You will threaten them?"
"If I must," signed Tanetoa.
"Even a giant cannot stand alone against so many," said the locathah. "We will come with you."
Tanetoa shook his head. "No. If the humans do not leave, you will kill more if you attack by surprise."
The locathah considered this, then smacked its lips in the piscine equivalent of a nod. "Eadro's wisdom is on you. We will ready ourselves for the hunt. May you eat and not be eaten."
It was a traditional good wish for anyone about to embark on a dangerous undertaking. Tanetoa responded with the less bellicose wish, "Swim with the currents."
Leaving the locathah to hover, Tanetoa returned to the surface and swam fifty yards toward the ships, then turned back to his island. Kani stood waist deep in the lagoon, holding the giant conch on her shoulder. A beautiful purple-striped shell with a crown of spines at the closed end, it was so large that even both of her large hands could not encircle it.
Tanetoa waved. Kani drew her arms back and hurled the conch. It arced over the reef ten yards in the air, then splashed into the water half a dozen strokes in front of Tanetoa. He swam after the shell, catching up to it as the last of the air left its chambers. He grabbed it by the flange of the opening, then stuck his head underwater and glanced back toward the channel mouth.
The locathah were continuing to stream into the lagoon, though a small party remained clustered just below the mouth of the channel. Their glassy eyes were fixed in his direction, but they showed no sign of being alarmed by the shell in his hand. Tanetoa did not know whether to be relieved or more worried than ever. He swam on the surface the rest of the way to the fleet.
The humans had already begun their landing preparations, having placed several skiffs in the water and started loading them with supplies. As before, they kept their ballistae trained on Tanetoa as he approached, but this time the emir showed himself at the rail as soon as the giant neared the largest carrack.
"Hail, Tanetoa!" said the emir. "I did not expect you to return so soon."
"I have come with a gift for the caleph." Tanetoa displayed the conch.
"Indeed?" The emir eyed the shell briefly, then feigned disinterest and looked back to Tanetoa. "Then you have decided to honor your duties as his ally?"
"There is nothing to be gained by denying him." Tanetoa grabbed the gunwale amidships, then gently pulled himself up and laid the conch on the deck. "This is the whale horn."
The emir and his humans seemed unimpressed. "The whale horn?"
"So you can sing with the whales," Tanetoa explained.
This drew a chorus of snickers from the crew, and the emir could not quite keep his lip from curling into a patronizing sneer. "I am sure the caleph will be most grateful. He has often spoken to me of longing to hear the whales sing."
"Then there is no need to stay." Still clinging to the side of the ship, Tanetoa had to crane his neck to see the emir's face. "I will show you how to blow it, then you can go."
The emir scowled. "Go? I thought I had made myself clear. The only place we are going is to your island."
Now it was Tanetoa's turn to frown. "What for? You have the whale horn. We have nothing else of value."
"Perhaps not-though you said the same thing before bringing us this, uh, magnificent whale horn."
"I said that only because I did not realize what you wanted," explained Tanetoa. "We have nothing else."
The emir gave him a silky smile. "If you say so."
"I do!" Tanetoa thundered. "You have what you came for, and now you must leave!"
The crew drew back at Tanetoa's display of anger.
The emir glanced nervously at the ballistae on a nearby deck and raised his hand, then narrowed his eyes at the giant. "There is nothing I must do, save what the caleph orders. The caleph thanks you for your gift, but I am still here to protect your island."
Tanetoa's heart sank. Then he did not send you for the whale horn?"
The caleph's reasons are not for you to know," said the emir. "It is enough that you know what he wishes."
Tanetoa shook his head. "But with the whale horn, you can sing with the whales. You can ask them to fight with you against the Enemy Beneath."
"So you have said, but that changes nothing. We will come ashore with the high tide-and you will help us."
A sick feeling came over Tanetoa. He gently released the gunwale and sank into the water, allowing the ship to rock slowly back to center. Whatever the caleph's reason for sending his fleet to the island, it was not the whale horn. There would be a battle.
Tanetoa swam two strokes backward, then stopped to stare up at the emir. "No! You are not going to land. If you try, there will be a terrible battle with the lo-cathah-"
"Locathah?" the emir gasped. His men peered into the water around the ships, and harpoons began to appear along the rails again. "The locathah are here?"
They are already in the lagoon." Tanetoa was encouraged by the emir's alarm. Perhaps he would leave if he believed his humans to be outnumbered. Thousands of them. They came to defend the island from you."
"And you let them?" The emir's face turned stormy.
"You're in alliance with them!"
"No, but I will-"
"Traitor!"
The emir brought his hand down sharply, and several deep pulses echoed across the water. Tanetoa ducked beneath the surface and saw a dark meshwork of giant harpoons dragging heavy lines through the sea around him. He dived for the bottom, but one of his legs went numb. When he tried to kick, there was something dragging in the water behind him. He emptied his lungs so his body would not be buoyed by a chest full of air, then spread his webbed fingers and pulled for the bottom.
A bolt of searing pain shot through Tanetoa's leg, and he was jerked to an abrupt halt. He glanced back to see a barbed hook tugging at the flesh of his thigh, the dark stripe of harpoon line stretched taut behind him. He began to slip toward the surface, being drawn up through the water by the humans at the other end of the cord.
Tanetoa swam one stroke toward the surface, then wrapped his hand into the thick rope and gave a mighty jerk. The line went slack, then something heavy splashed into the sea. When the wave circle cleared, he saw the crosslike shape of a wooden ballista floating at the other end of the harpoon line.
Human wizards began to unleash their spells, and the sea erupted into a storm of crackling flashes and ear-shattering blasts. Tanetoa's head exploded into a tempest of blinding lights and dizzying concussions, then he went limp and felt himself floating toward the surface. He shook his head clear and flailed his leaden arms through the water, slowly dragging himself into the depths and away from the ships.
A dozen strokes later, he came to the end of the harpoon line and felt the ballista dragging through the water behind him. He pulled his knife from its ankle sheath and turned to cut the line. A cluster of small hand-hurled harpoons came slicing down behind him, and he saw the oblong hulls of four skiffs plowing through the water alongside the heavy ballista. Without cutting the line, Tanetoa turned and swam for his reef. The humans were not yet close enough to hit him with their little harpoons, but if he paused to cut the thick rope, they would be.
