THE RED DRY mountains looked as though they had been folded directly up out of the desert plain, cliffs painted with broad stripes of white and ochre, without any softening foothills at their base. They remained stubbornly distant: for a whole day Temeraire flew at a steady pace and seemed to come no closer, the mountains drawing themselves ever upwards and out of reach, until suddenly canyon walls were rising to either side. In the space of ten minutes’ flight the sky and desert vanished away behind them, and abruptly Laurence understood the red mountains were themselves the foothills for the towering white-clad peaks beyond.

They camped in wide meadowlands high in the mountains, fortressed by the peaks and sparsely furred with sea-green grass, small yellow flowers standing up like flags from the dusty ground. Horned black cattle with bright red tassels dangling over their foreheads eyed them warily as Tharkay negotiated their price with the herdsmen in their round, conical-roofed huts. At night a few white flakes came silently drifting down, glittering against the night; they melted snow in a great leather pot for Temeraire to drink.

Occasionally, they heard a faint, far-off call of dragons that made Temeraire prick up his ruff; and once in the distance saw a feral pair go spiraling up chasing each other’s tails, crying out in shrill joyful voices before they vanished around the other side of a mountain. Tharkay made them put veils over their eyes, to shield against the brilliant glare; even Temeraire had to submit to this treatment, and very odd he looked with the thin white silk wrapped around his head like a blindfold. Even with such precautions, their faces grew pink and sunburnt for the first few days.

“We will need to take food with us, past Irkeshtam,” Tharkay said, and when they had made camp outside the old run-down fortress, he went away and returned nearly an hour later with three locals herding along a small band of fat, short-legged pigs.

“You mean to take them up alive?” Granby cried, staring. “They will squeal themselves hoarse and then die of terror.”

But the pigs seemed curiously somnolent and indifferent to Temeraire’s presence, much to his puzzlement: he even leaned over and nudged at one with his nose, and it only yawned and sat down thump on its hindquarters in the snow. One of the others kept attempting to walk into the brick wall of the fortress, and had to be hauled repeatedly back by its minders. “I put opium in their feed,” Tharkay said, in answer to Laurence’s confusion. “We will let the drug wear off when we make camp, and he will eat after we have rested; then the rest we dose again.”

Laurence was wary of this notion, and not inclined to trust Tharkay’s offhand assurance; he watched closely after Temeraire ate the first pig. It went to its death perfectly sober and kicking all the way, and Temeraire showed no inclination afterwards to begin flying in mad circles; although he did fall into rather a deeper sleep than usual, and snored loud enough to rattle.

The pass itself climbed so high they left the clouds below them, and all the rest of the earth; only the nearby mountain peaks kept them company. Temeraire panted for breath, now and again, and had to let himself down to rest wherever the ground permitted, leaving his body outlined in the snow as he lifted away. There was a queer sense of watchfulness, all the day long; Temeraire kept looking around as he flew, and pausing to hover in mid-air, with a low uneasy rumbling.

Having cleared the pass, they set down for the evening in a small valley sheltered from the wind between two great peaks with the ground clear of snow, and anchored their tents at the bottom of the cliff face; the pigs they penned up with a fence of kindling and rope, and let them range freely. Temeraire paced his side of the valley a few times, and then settled himself down with his tail still twitching; Laurence came to sit beside him with his tea. “It is not that I hear anything,” Temeraire said, uncertainly, “but I feel as though I ought to be hearing something.”

“We have a good position here: we cannot be come upon by surprise, at least,” Laurence said. “Do not let it keep you from sleeping: we have posted a watch.”

“We are very high in the mountains,” Tharkay said unexpectedly, startling Laurence: he had not heard the guide come towards them. “You may only be feeling the change, and the difficulty of breathing: the air has less body.”

“Is that why it is so hard to breathe?” Temeraire said, and abruptly sat up on his haunches; the pigs began to squeal and run as nearly a dozen dragons, motley in colors and size, came winging down towards them. Most of them landed skillfully clinging to the cliff face, peering down towards the tents, faces sleek and clever and hungry looking; the largest three dropped down between Temeraire and the makeshift pen, and sat up on their haunches, challengingly.

They were none of them large: the lead fellow something smaller than a Yellow Reaper, pale grey with brown markings and a single crimson patch across half his face and down his neck, with a great many spiny horns around his head; he bared his teeth and hissed, the horns bristling. His two companions were of slightly larger size, one a collection of bright blues and the other dark grey; and all three heavily scarred with the relics of a great many battles, the marks of tooth and claw.

Temeraire outweighed nearly all three of them together: he sat up very straight and his ruff opened wide, stretching like a frill around his head, and gave a small growling roar in answer: a warning. The ferals, so isolated from all the world, likely would not know to fear Celestials as anything other than large dragons, for their size and strength; but the strange ability of the divine wind was by far their most dangerous weapon, and without visible means could shatter stone and wood and bone. Temeraire did not now raise the divine wind against them, but there was an edge of it in his roaring, enough to rattle Laurence’s bones; before it, the ferals quailed, the red-patch leader’s horns flattening against his neck, and like a flock of alarmed birds they all flung themselves up and out of the valley.

“Oh; but I did not do anything, yet,” Temeraire said, puzzled and a little disappointed. Above them the mountains were still grumbling with the echoes of his roar, piling them one on another into a continuous roll of thunder, a sound almost magnified beyond the original. The white face of the peak stirred at the noise, sighed, and let go its hold upon the stone, the entire slab of snow and ice sliding gently free; for a moment yet it kept its shape, moving with slow and stately grace, then cracks like spiderwebs spread across its surface, and the whole collapsed into a great billowing cloud and came galloping down the slope towards the camp.

Laurence felt like the captain of a ship on her beam-ends, seeing the wave that would make her broach-to: in perfect consciousness of disaster and powerless to avert it; there was no time to do anything at all but watch. So quickly did the avalanche come that a couple of the luckless ferals, though they had all tried at once to flee, were swept up in its path. Tharkay was shouting, “Get away! Get away from the cliff!” to the men standing around the tents, pitched directly in the path; but even as he cried out, the vast eruption spilled off the slope, swept over the camp, and then the boiling mass came seething and roaring across the green valley floor.

First there came a shock of cold air, almost physical in its force; Laurence was flung back against Temeraire’s great bulk, reaching out to catch Tharkay’s arm as the guide stumbled back, and then the cloud itself struck and tore away the world: like being thrust abruptly face-forward into deep snow and held down, a cool muffling eerie blue all around him, a hollow rushing sound in his ears. Laurence opened his mouth for air that was not there, flakes and slivers of ice like knives scraping his face, his lungs heaving against the pressure on his chest, on his limbs, his arms spread-eagled and pressed back so that his shoulders ached.
