They were not long in the mountains before Larch accepted, bitterly, that it was an impossible hiding place. It wasn't the cold that was the problem, though autumn here was as raw as midwinter had been on the lord's estate. It wasn't the terrain either, though the scrub was hard and sharp, and they slept on rock every night, and there was no place even to imagine growing vegetables or grain. It was the predators. Not a week went by that Larch didn't have to defend against some attack. Mountain lions, bears, wolves. The enormous birds, the raptors, with a wingspan twice the height of a man. Some of the creatures were territorial, all of them were vicious, and as winter closed in bleakly around Larch and Immiker, all of them were starving. Their horse was lost one day to a pair of mountain lions.

At night, inside the thorny shelter Larch had built of sticks and scrub, he would pull the boy into the warmth of his coat and listen for the howls, the tumbled stones down the slope, the screeches, that meant an animal had scented them. At the first telltale sound he would strap the sleeping boy into the carrier on his chest. He would light as powerful a torch as he had the fuel for, go out of the shelter, and stand there, holding off the attack with fire and sword. Sometimes he stood there for hours. Larch didn't get a lot of sleep.

He wasn't eating much either.

"You'll make yourself sick if you keep eating so much," Immiker said to Larch over their paltry dinner of stringy wolf meat and water.

Larch stopped chewing immediately, for sickness would make it harder to defend the boy. He handed over the majority of his portion. "Thank you for the warning, son."

They ate quietly for a while, Immiker devouring Larch's food. "What if we went higher into the mountains and crossed to the other side?" Immiker asked.

Larch looked into the boy's mismatched eyes. "Is that what you think we should do?"

Immiker shrugged his small shoulders. "Could we survive the crossing?"

"Do you think we could?" Larch asked, and then shook himself as he heard his own question. The child was three years old and knew nothing of crossing mountains. It was a sign of Larch's fatigue, that he groped so desperately and so often for his son's opinion.

"We would not survive," Larch said firmly. "I've heard of no one who has ever made it across the mountains to the east, either here or in Estill or Nander. I know nothing of the land beyond the seven kingdoms, except for tall tales the eastern people tell about rainbow-coloured monsters and underground labyrinths."

"Then you'll have to bring me back down into the hills, Father, and hide me. You must protect me."

Larch's mind was foggy, tired, starved, and shot through with one lightning bolt of clarity, which was his determination to do what Immiker said.

Snow was falling as Larch picked his way down a sheer slope. The boy was strapped inside his coat. Larch's sword, his bow and arrows, some blankets and bundled scraps of meat hung on his back. When the great brown raptor appeared over a distant ridge, Larch reached for his bow tiredly. But the bird lunged so fast that all in an instant it was too close to shoot. Larch stumbled away from the creature, fell, and felt himself sliding downward. He braced his arms before him to shield the child, whose screams rose above the screams of the bird: "Protect me, Father! You must protect me, Father!"

Suddenly the slope under Larch's back gave way and they were falling through darkness. An avalanche, Larch thought numbly, every nerve in his body still focused on protecting the child under his coat. His shoulder hit against something sharp and Larch felt tearing flesh, and wetness, warmth. Strange, to be plunging downward like this. The drop was heady, dizzying, as if it were vertical, a free fall; and just before he slipped into unconsciousness Larch wondered if they were falling through the mountain to the floor of the earth.

Larch jackknifed a wake, frantic with one thought: Immiker. The boy's body wasn't touching his, and the straps hung from his chest, empty. Larch felt around with his hands, whimpering. It was dark. The surface on which he lay was hard and slick, like slimey ice. He shifted to extend his reach and screamed suddenly, incoherently, at the pain that ripped through his shoulder and head. Nausea surged in his throat. He fought it down and lay still again, weeping helplessly, and moaning the boy's name.

"All right, Father," Immiker's voice said, very close beside him. "Stop crying and get up."

Larch's weeping turned to sobs of relief.

"Get up, Father. I've explored. There's a tunnel and we must go."

"Are you hurt?"

"I'm cold and hungry. Get up."

Larch tried to lift his head, and cried out, almost blacked out. "It's no use. The pain is too great."

"The pain is not so great that you can't get up," Immiker said, and when Larch tried again he found that the boy was right. It was excruciating, and he vomited once or twice, but it was not so bad that he couldn't prop himself on his knees and his uninjured arm, and crawl across the icy surface behind his son.

"Where – " he gasped, and then abandoned his question. It was too much work.

"We fell through a crack in the mountain," Immiker said. "We slid. There's a tunnel."

Larch didn't understand, and forward progress took so much concentration that he stopped trying to. The way was slippery and downhill. The place they went toward was slightly darker than the place they came from. His son's small form scuttled down the slope ahead of him.

"There's a drop," Immiker said, but comprehension came so slowly to Larch that before he understood, he fell, tumbling knees over neck off a short ledge. He landed on his injured shoulder and momentarily lost consciousness. He woke to a cold breeze and a musty smell that hurt his head. He was in a narrow space, crammed between close walls. He tried to ask whether his fall had injured the boy, but only managed a moan.

"Which way?" Immiker's voice asked.

Larch didn't know what he meant, and moaned again.

Immiker's voice was tired, and impatient. "I've told you, it's a tunnel. I've felt along the wall in both directions. Choose which way, Father. Take me out of this place."

The ways were identically dim, identically musty, but Larch needed to choose, if it was what the boy thought best. He shifted himself carefully. His head hurt less when he faced the breeze than when he turned his back to it. This decided him. They would walk toward the source of the breeze.

And that is why, after four days of bleeding, stumbling and starving, after four days of Immiker reminding him repeatedly that he was well enough to keep walking, Larch and Immiker stepped out of the tunnel not into the light of the Monsean foothills, but into that of a strange land on the other side of the Monsean peaks. An eastern land neither of them had heard of except for foolish tales told over Monsean dinners – tales of rainbow-coloured monsters and underground labyrinths.

Larch wondered sometimes if the blow to his head on the day he'd fallen through the mountain had caused some hurt to his brain. The more time he spent in this new land, the more he struggled against a fog hovering on the edge of his mind. The people here spoke differently and Larch struggled with the strange words, the strange sounds. He depended on Immiker to translate. As time passed he depended on Immiker to explain a great many things.

This land was mountainous, stormy and rough. It was called the Dells. Variations of the animals Larch had known in Monsea lived in the Dells – normal animals, with appearances and behaviour Larch understood and recognised. But also in the Dells lived colourful, astonishing creatures that the Dellian people called monsters. It was their unusual colouration that identified them as monsters, because in every other physical particular they were like normal Dellian animals. They had the shape of Dellian horses, Dellian turtles, mountain lions, raptors, dragonflies, bears; but they were ranges of fuchsia, turquoise, bronze, iridescent green. A dappled grey horse in the Dells was a horse. A sunset orange horse was a monster.
