Prologue
Even stars die.
They may grow old, they may seem inconceivable when held against the flickering candle of our own
existence, yet they too have lives that are shaped by the same universe, the same immutable laws as are our
own lives.
In the measure of Deep Time the brief moment of existence of all the stars in the universe is as the moment a
butterfly lives compared with all the summers that will ever be. for the red giant, galactic summer is over and
winter is approaching. Its hydrogen fuel long since exhausted, this old, mad sun has consumed its inner
worlds and barely noticed their absence. Burning helium now as a lingering precursor to death, the red giant
prepares to shrug off its outer mantle of remaining hydrogen and take its remaining family of planets with it
into oblivion.
Within the star, a schism: its core shrinking and growing ever hotter even as its outer layers expand and cool.
Soon now will come the moment of death, of explosion - the surviving solar matter burning in a tiny
incandescent lump at the heart of a nebula composed of the tattered shreds of its own corpse.
Still from death comes life. A truth unchanging while there is yet energy in the universe.
While the red giant continues slowly to die, life on its many worlds continues to grow and evolve.
It was an old world, one from which the fire had gone. A dark backwater, an eddy in the current of life, with no
bright future or
destiny, forgotten by any who might once have observed it or experienced it for however brief a moment.
Its chill plains and freezing mountains, its sparse black vegetation and cold-sculpted animal life were left to
just one pair of eyes to study: a single mind to look up at the sky and wonder if it would kill those who lived
beneath it today, or play with them a while longer before dismissing them from this life.
Skywatcher glanced at the iron-grey clouds that scraped the tops of the White Mountains and tried to work
out how long it would be before the snow on the ground covered the tracks of the fast-moving herd of
hornrunners. Skywatcher and his brother, Fastblade, had been tracking the herd for three days. It was his
responsibility to make sure the sky would allow this kill. If Fastblade did not find the hornrunners' winter nest
before the snow concealed it from view, then many would die from starvation in the coming months, and the
hornrunners would emerge from their hibernation to a world cleansed by cold of all but the most isolated -
probably cannibalistic - pockets of human life.
Skywatcher pulled his furs more tightly around his chapped face, his nose clogged with the greasy stink of
animal fat smeared upon his skin to protect it from the biting cold. Fastblade had no such protection.
Fastblade needed every sense clear and unclouded. Whereas this weather was, for Skywatcher, the fear and
wonder of a cruel friend, the same weather for Fastblade was little more than a tool with which he focused his
mind acutely on the task at hand. The tracking of the nest.
Two very different men, then, Skywatcher and Fastblade. Yet, though the sky affected them in different ways,
it made them brothers, too. For without the sky to determine their actions they would surely be little more
than mindless animals living easily from an endless bounty of summer food. Skywatcher had heard many of
the village curse the sky, the space above, the endless night drawing close about their world. He had heard
the prayers to a dying sun, swollen with cold crimson light, whose nearness brought little comfort beyond the
beauty of dawn and sunset across the frost-laden plains. But, unlike his fellow men, Skywatcher was not
afraid. Not of the sky. How could he be? The sky was his friend and loved him. The sky brought him life in the
form of birds too cold to fly, of snow to make water, of berries and meat preserved in the frost from one
season to the next. Skywatcher knew where life came from on this world. And he loved the sky in turn for
making every day a challenge, for making every hour and every moment linked and full of meaning, like the
crystal spokes of a single snowflake.
Fastblade thought it was all birdlime, of course.
