airship was heading into danger, but—incredibly—its captain appeared not to notice.
“What does the fool think he’s doing?” Toller said, speaking aloud although there was
nobody within earshot. He shaded his eyes from the sun to harden his perception of what
was happening. The background was a familiar one to anybody who lived in those
longitudes of Land—flawless indigo sea, a sky of pale blue feathered with white, and the
misty vastness of the sister world, Overland, hanging motionless near the zenith, its disk
crossed again and again by swathes of cloud. In spite of the foreday glare a number of stars
were visible, including the nine brightest which made up the constellation of the Tree.
Against that backdrop the airship was drifting in on a light sea breeze, the commander
conserving power crystals. The vessel was heading directly towards the shore, its
blue-and-grey envelope foreshortened to a circle, a tiny visual echo of Overland. It was
making steady progress, but what its captain had apparently failed to appreciate was that
the onshore breeze in which he was travelling was very shallow, with a depth of not more
than three-hundred feet. Above it and moving in the opposite direction was a westerly wind
streaming down from the Haffanger Plateau.
Toller could trace the flow and counterflow of air with precision because the columns of
vapour from the pikon reduction pans along the shore were drifting inland only a short
distance before rising and being wafted back out to sea. Among those man-made bands of
mist were ribbons of cloud from the roof of the plateau—therein lay the danger to the
airship.
Toller took from his pocket the stubby telescope he had carried since childhood and
used it to scan the cloud layers. As he had half expected, he was able within seconds to
pick out several blurry specks of blue and magenta suspended in the matrix of white vapour.
A casual observer might have failed to notice them at all, or have dismissed the vague
motes as an optical effect, but Toller’s sense of alarm grew more intense. The fact that he
had been able to spot some ptertha so quickly meant that the entire cloud must be heavily
seeded with them, invisibly bearing hundreds of the creatures towards the airship.
“Use a sunwriter,” he bellowed with the full power of his lungs. “Tell the fool to veer off, or
go up or down, or . . . .”
Rendered incoherent by urgency, Toller looked all about him as he tried to decide on a
course of action. The only people visible among the rectangular pans and fuel bins were
semi-naked stokers and rakers. It appeared that all of the overseers and clerks were inside
the wide-eaved buildings of the station proper, escaping the day’s increasing heat. The low
structures were of traditional Kolcorronian design—orange and yellow brick laid in complex
diamond patterns, dressed with red sand-stone at all corners and edges—and had
something of the look of snakes drowsing in the intense sunlight. Toller could not even see
any officials at the narrow vertical windows. Pressing a hand to his sword to hold it steady,
he ran towards the supervisors’ building.
Toller was unusually tall and muscular for a member of one of the philosophy orders, and
workers tending the pikon pans hastily moved aside to avoid impeding his progress. Just as
he was reaching the single-storey building a junior recorder, Comdac Gurra, emerged from
it carrying a sunwriter. On seeing Toller bearing down on him, Gurra flinched and made as if
to hand the instrument over. Toller waved it away.
“You do it,” he said impatiently, covering up the fact that he would have been too slow at
stringing the words of a message together. “You’ve got the thing in your hands—what are
you waiting for?”
“I’m sorry, Toller.” Gurra aimed the sunwriter at the approaching airship and the glass
slats inside it clacked as he began to operate the trigger.
Toller hopped from one foot to the other as he watched for some evidence that the pilot
was receiving and heeding the beamed warning. The ship drifted onwards, blind and
serene. Toller raised his telescope and concentrated his gaze on the blue-painted gondola,
noting with some surprise that it bore the plume-and-sword symbol which proclaimed the
