It is a frozen world.
To the south there are forests. But to the north the trees — hundred-year-old spruce barely six feet tall, stunted by cold and wind — grow ever more thinly scattered, until they peter out altogether.
And beyond, where it is too cold for the hardiest tree, there is only the tundra: an immense, undulating plain, a white monotony broken by splinters of rock. Very little snow falls here, but unimpeded winds whip up ice crystals, giving the illusion of frequent blizzards. Even the outcropping rock has been shattered by millennia of frost to a rough, unstable scree.
Under the silent stars nothing stirs but the ruffled surface of the larger lakes, tormented by the breeze. The smaller lakes are frozen completely. From this place there is nothing but snow and ice and frozen ocean, all the way to the North Pole.
It seems impossible that anything should live here. And yet there is life.
There are birds here: snowy owls and ptarmigan, able to survive the bleakest midwinter by sheltering in holes in the snow. And later in the season many thousands more birds will migrate here from their winter homes across the planet. More life, plant and animal, lies dormant under the snow, waiting for the brief glory of summer. And to the north, on the frozen ocean itself, live polar bears and their prey: sea mammals like seals and walruses.
And there is more.
The stars are scintillating now. A vicious wind is rising, and the ice fields to the north are shrouded in a gray haze.
And out of that haze something looms: a mountainous shape, seemingly too massive to move, yet move it does. As it approaches through the obscuring mist, more of its form becomes visible: a body round as an eroded rock, head dropped down before it as it probes for saxifrage buds beneath the snow, the whole covered in a layer of thick, red-brown hair.
The great head rears up. A trunk comes questing, and immense tusks sweep. An eye opens, warm, brown, intense, startlingly human.
This is not a vision from prehistory. This is real: a living thing a hundred times as massive as any human, a living thing prospering in this frozen desert.
The great trunk lifts, and the woolly mammoth trumpets her ancient songs of blood and wisdom.
Her name is Silverhair.
