The nauallis nodded, arms wrapped tight around his chest. "Two show signs of damage. I marked them with colored tape. They've not cracked through."

"Yet." Gretchen brushed melting frost out of the way and began unscrewing the two valves holding the broken section of line. "We'll wrap them in steeltape later." She stifled a yawn. "This afternoon we'll press on and see if we can reach the camp in one long flight."

"Very well." Gretchen felt the old man shivering, even with his suit and the blankets and djellaba.

"Get in the tent," she said, giving him a concerned look. "You're losing too much body heat out here."

For a moment, Anderssen thought he would refuse and some sharp words about pigheaded men were on the tip of her tongue, but he nodded and climbed stiffly down. He's had a big day, she thought, watching him disappear in the direction of the tent. Almost crashed twice. Very lucky, these judges, very lucky.

The broken section of line came free in her hands and she put the part aside. A little can of compressed air blew out the usual gunk fouling the valves. "Huh. Should talk to Delores and Parker about maintenance on this bird…needs a tune-up."

Squinting, her goggles dialed up into a moderately high magnification, Gretchen eased the new line into the first valve. Her fingers were stiff from the cold, making fine work difficult. After the third failed attempt to line them up, she eased herself back and took a moment to warm her hands on the heater. Her eyes, back and shoulders were hurting from tension and cold and weariness. Got to loosen up, Gretchen thought, flexing her gloved fingers. Maybe I should empty my mind and count, she smiled a little at the memory of Hummingbird's pedantic, measured voice. Her brow furrowed, considering the situation. Maybe I should…maybe I should try this with my eyes closed.

The tube felt cold and round beneath her fingers, only a few centimeters long, ending in two delicate valve stems and a counter-rotating jacket to fix the connection tight. Gretchen let her shoulders and arms settle. She let herself count until the busy noise in her thoughts settled down and then faded away.

The warmth of the heater was almost hot on her left shoulder, but she shifted the tube gently until a familiar prickling heat suffused her fingertips. Trying not to lick her chapped lips nervously, Gretchen leaned forward slightly, letting the tube slide into proximity with the sleeve. Eyes still closed, working in complete, chill darkness, she slid the tube into the stem and finger-tightened the jacket, first on one side, then on the other. A moment later – it seemed like only seconds – she opened her eyes and smiled slightly to see the tube in place. That was easy.

The Midge tool kit had a specialized microdriver, which torqued down the two connections to the proper, factory-approved tightness. Gretchen sighed in relief when she was done and closed up the compartment with trembling fingers. A wave of complete exhaustion had crept up upon her and now dragged at every muscle in her body.

"Dawn soon," she muttered, climbing very stiffly down from the wing. The tools and the portable heater were slung over her shoulder, making what felt like an enormous, bone-crushing weight. "At least the tent will be nice and warm."

But the tent was too hot and the ground too hard. Hummingbird was snoring again, and she couldn't take the heep-snort-heep sound of his breathing. After laying in the sleepbag for an hour, too tired to remove her breather mask or even brush her teeth, Gretchen crawled out of the tent and into the mind-numbing cold again.

She climbed back up to the ultralights and made a desultory circuit, checking their tie-downs and anchors. The old Mйxica had done a fine job, each cable taut and balanced. Irritated, Gretchen walked to the edge of the mesa, stepping carefully among weathered, wind-blasted slabs and boulders.

The canyon below was entirely, impenetrably dark. Anderssen considered pitching a glowbean over the edge, just to see what might be revealed in the flickering blue-green light. The stars gleamed on her goggles, very bright and steady. The air had chilled to a supernal level of stillness, much as it did during the polar winter on Old Mars. Good place for a telescope, she thought, beginning to walk along the rim of the mesa, her back to the eastern sky. But is there anything to see out here?

Ephesus sat at the edge of one of the abyssal gulfs running through the spiral arm. There were few nearby suns, only clouds of dust, dark matter and interstellar gas. A lonely outpost on the verge of nothingness, hundreds of light years from another habitable world. Gretchen wondered, as she climbed a rough, rectangular outcropping, if the long-dead inhabitants had ever managed to pierce the envelope of air around their home world. Had satellites or orbital stations seen the valkar burst from the nothingness of hyperspace? Had anyone tried to escape? Or were the Ephesians still grubbing in the mud, trying to trap their dinner in woven nets or pit traps when the sky darkened with the killing cloud? A million years…Earth was still a raw, primitive world. Only megafauna and protohominids fighting to survive in Pliocene swamps. Did we escape a similar fate by some quirk of chance?

The thought made her feel despondent. Her heart did not easily agree with the prospect of a universe where man only lived and thrived by the fall of some random cosmic die. Gretchen realized Hummingbird's vision of a universe of frightful powers – of gods – offered a strange kind of comfort. He believes men can alter the course of fate. He believes he can divert the engines of chance. Huh.

Beyond the outcropping, a deep crevice split in the face of the mesa. I should head back…she started to remind herself, but then…what's that? A light?

Anderssen stopped and knelt down, peering over the edge into the darkness. There was a light. There were many lights, spreading in a delicate cobweb across the rock, making the ravine gleam and glitter like the stars above, a hidden galaxy of jeweled-colors and shining motes.

Like moss, a firemoss, she thought, lips quirking in a smile. Life blooming from nothing. Even here, at the edge of annihilation. Gretchen concentrated on the nearest filaments and was rewarded by a vision of delicate tendrils radiating out from a cone-shaped core. The surface seemed to glisten, though she doubted there was any kind of moisture in this system. A superconducting energy trap, maybe? I wish Sinclair and Tukhachevsky were here… They would love this. Ha! They'll be jealous when I tell them about all the things I've seen. God, I even miss that tub vodka of theirs.

A sound interrupted her delight. Gretchen looked up, surprised. A cloaked figure knelt a few meters away, silhouetted by a wash of stars, djellaba and kaffiyeh wrapped expertly around narrow shoulders. An instant of surprise was replaced by a certain sense of recognition.

"What are you?" Gretchen stood up slowly, hoping to leave the firemoss undisturbed. Flakes of rock spilled away from her gloves, falling among the thready clusters. "You're not Russovsky, are you?"

"I am," answered the dark outline. The voice was hoarse, rusty, as if long unused. The shape stood as well, wiry blond hair hanging loose around her shoulders. "What are you?"

"A human being," Gretchen said, then stopped, horrified. Hummingbird wouldn't want her to give anything away. "A visitor."

"Am I a human being?" Russovsky came close and Gretchen could see her pale, lean face glowing with an inner light. Stunned, Gretchen realized she was seeing the pattern of a vibrant crystalline lattice seeping through the woman's skin. "My memories are strange. I was flying, high above the world. I was walking under the sea, among the bones of the dead."
