The sense of wonder he would normally have enjoyed at the discovery of such a magnificent quirk of nature was canceled out by the realization that the weather wasn’t going to improve for tomorrow morning. Evolution hadn’t come up with this crystalline biota for warm climates; in fact, it was probably a form of reverse evolution; arctic-style plants expanding with the final ice age, then struggling for survival in a degenerating environment until their genes refined the ultimate winter-attuned chemistry. And how many millions of years of declining heat would it take to produce something this sophisticated? They’d missed this planet’s last springtime by geological eras.
He hurried back to the tent, too guilty to look at the horse and pony as he passed them. Orion had started cooking a meal on the heatbricks. Condensation was dripping off the inner lining.
“I can’t see a fire,” the boy said as Ozzie closed up the seal.
“This wood won’t light. Sorry.”
“I can feel my toes again.”
“Good. This insulation should keep enough heat in overnight. We’ll be fine in our sleeping bags.” He was doing a rough inventory. There were only eleven heatbricks left. Enough to keep them going for—realistically—three days. They could afford to walk forward for one more day, no more. If the path didn’t take them to a warmer world by tomorrow night, they’d have to turn back. No: Just see what’s around the next curve; no: I think it’s getting brighter. If things didn’t genuinely change, he couldn’t take the risk. There was no margin for error left anymore. And there would be nobody to return his memorycell to the Commonwealth for a re-life procedure. In fact, how long before anyone even notices I’ve gone missing?
Ozzie dug his sewing kit out of the pack. “Ah! This is going to be useful. I’ve an idea for some things we need tomorrow. How are you with sewing?”
“I’ve spoilt your chances, haven’t I?” Orion said. “You would have made it if it wasn’t for me.”
“Hey, man.” Ozzie tried to smile, but his lips cracked open. He dabbed at the drops of blood. “No way. We’re really doing it, we’re walking the deep paths. It’s your friendship gift that got us this far.”
Orion took the pendant out. They both stared at its dark lifeless surface.
“Try it again in the morning,” Ozzie said.
Polly and the pony were frozen solid when they emerged from the tent the next morning.
“They wouldn’t have felt anything,” Ozzie said when Orion stopped to look at them. His voice was muted by the thick fabric mask he’d carefully stitched together last evening. He was wearing every piece of clothing it was possible to wear, as was Orion. The boy looked as though his coat had inflated out to twice its normal size; even his gloves were covered in crude, bulging wraps of modified socks, like small balloons.
“They would have felt cold,” Orion said.
Ozzie couldn’t see his eyes behind the sunglasses he was wearing, but he guessed the boy was feeling a great deal of remorse. With his more practical gauntlets, it was Ozzie who dismantled the tent and put the packs back on the lontrus. The cold was every bit as debilitating as the day before, but the little extra pieces of protective garments they’d put together helped to keep it from attacking their skin. The temperature was far too low for the snow to melt, which eliminated the chance of their feet getting wet—a lethal development.
The breeze had scattered the loose top layer of snow about, but there were still a few signs of the footprints they’d followed yesterday. Ozzie pushed at the lontrus’s rump, then finally gave the miserable beast a kick. It started moving, emitting a wounded wailing.
Optimism, which had been high as Ozzie climbed out of the tent to greet the day, drained away quickly. Though it never faltered, the lontrus moved slowly. Every step Ozzie made was an effort, moving the weight of clothes, pushing his feet through the cloying snow. Warmth left him gradually. There was no one place it was leaking out from, rather an all-over emission, slowly and relentlessly chilling him. Every time he tipped his head up to the high cerise clouds drifting across the rosy sky he could imagine currents of his body heat flowing upward to fill the insatiable icy void.
Some dreary time later, he noticed the crystal trees were shorter than before. Their perma-cloak of snow was also thinner, with the upper branches poking clear. Sunlight glinted and glimmered from their multiple facets, splitting into a prismatic spectrum entirely of red, from a gentle light rose to deep gloomy claret. There was less snow beneath their feet as well. Ozzie had long since lost sight of the Silfen footprints.
He was so intent on trying to see through the thinning crystal pillars he didn’t see Orion slowing. The boy grabbed at matted strands of the lontrus’s pelt, which made the animal whine in protest.
“Do you need a break?” Ozzie asked.
“No. It’s so cold, Ozzie. Really cold. I’m frightened.”
