Mk had been digging with a busted shovel for six hours when the wind erased his hole. He stood on the ridge above Star West and watched the sand pour back in like water. Somewhere under that desert lay a fleet of ships older than the town itself, or so his grandfather had sworn on his deathbed. Everyone else in Star West called it a drunk's story. Mk called it the only thing worth doing, which was why he had spent his last coin on a shovel that snapped before noon. He walked back into town with the broken handle over his shoulder. The trading post on the main row sold ground-scanners, the kind prospectors used to find water and metal. He knew the price. He did not have it. He sat down on a weathered chair outside the post and counted what he had left: three copper bits, a folding knife, and a leather pouch of pigments his grandfather had used to mark maps. Red ochre, yellow, white, black. Ceremonial paints, the old man had called them, though he had used them for surveying. Mk turned the pouch over in his hand and thought about what a scanner cost and what he was willing to trade to get one. Not the paints. Anything but the paints. Then Finn Jarro came out of the post, and Mk stood up. Finn ran the only rig in Star West with a working sand-scanner mounted to the axle. Mk had watched him charge miners double for a single sweep. Mk stepped in front of him and offered the deal fast, before he could talk himself out of it. One week of free labor on Finn's claim, in exchange for one afternoon with the scanner on a patch of dune Mk would choose. Finn laughed. Then Finn looked at Mk's face and stopped laughing. He said two weeks, not one, and Mk said done before Finn finished the sentence. They shook on it in front of the post. Mk had traded his next fourteen days for a single afternoon of answers, and he would spend them swinging a pick on another man's dirt while the wind kept burying the only thing he cared about.

Mk walked out of Star West at first light with the handshake still fresh on his palm. Two weeks on Finn Jarro's claim. Two weeks of wind piling sand over the one patch of desert that mattered. He climbed the ridge above his dig site and looked down. The hole he had scraped yesterday was already gone. By the time he earned the scanner, every ripple that hinted at the fleet would be flat as a table. He needed to mark the site before he started Finn's labor. Something the wind could not erase. The gecko shifted on his wrist as he turned toward the low huts at the edge of the flats. An old woman named Roma Lyle kept a clay hut out there and sold rope, water, and dried meat to anyone crossing through. She had watched him dig for weeks and never once laughed. Mk ducked under her reed awning. Roma sat on a stool cleaning a lamp. He asked if she knew a way to fix a location in the desert without a stake, without a flag, without anything the wind could take. Roma set the lamp down. She said stakes were for miners. She said hunters used a line of three, sighted against something that would not move. She walked him outside and pointed east. Two knobs of dark rock stood on the far horizon, and a third leaned between them. If he stood on his dig site, she said, and the leaning rock split the gap between the other two, he was standing on the same grain of sand every time. No wind could shift stone that big. Mk went back up the ridge before noon. He walked the dune until the three rocks lined up the way Roma had described. He drove his broken shovel handle into the sand at his feet, just to feel the spot, then pulled it out. He paced ten steps north, ten east, ten south, ten west, and checked the sightline from each. He could find the center again from any of them. He wrote the count and the bearing on the inside of his pouch flap, next to the pigments he had refused to sell. That afternoon he rode out to Finn's claim and started swinging a pick. Finn watched from the shade and said nothing about the dust on Mk's boots. On the walk in, Mk had passed two figures loading a cart near Frontier Row, a man he recognized as Running Bear and a girl he had seen at the well, Aiyana Redfeather. They were headed the same direction he had just come from, toward the flats past Roma's hut. Mk did not think about it until his second swing. He drove the pick down. The site was fixed. The wind could not take it now. But someone else was walking toward it, and he had thirteen days and a half left before he could go back.

Mk swung the pick until his shoulders burned. Finn Jarro sat in the shade of a tin roof and drank from a clay jug. Thirteen days. Thirteen days while Running Bear and Aiyana Redfeather walked toward the flats past Roma's hut. Mk drove the pick again and thought about the three rocks on the horizon. The sightline would hold. A boot print next to it would not. At midday Mk set the pick down and walked into the shade. He told Finn he needed to hire a watcher for his own patch of ground. Finn laughed once, short. He said a watcher cost coin, and Mk had none. Mk said he would trade a day off Finn's count for every day someone sat on his dig. Finn shook his head. A deal was a deal. Two weeks meant two weeks. Mk walked back to the pick. The gecko shifted on his wrist. He thought of the pouch flap with the bearing written on it, and the pigments folded inside. He would not trade them. He needed another way. That evening a man came along the trail from the flats. He wore hide leggings and carried a bow. He stopped at the edge of Finn's claim and watched Mk work for a long minute. Mk set the pick down and walked over. The man said his name was Running Wolf. He said he was tracking men who had taken sacred ground from his people. He said the trail led through the flats past a clay hut and out onto the open dune. Mk described the three rocks and the sightline. He said there was a spot on that dune he could not leave and could not guard. He asked Running Wolf to camp on it for twelve days. In return, Mk would give him the names and faces of every stranger who came through Star West asking about the flats. Traders passed Finn's claim every day. Mk heard them talk. Running Wolf listened. He asked how Mk would know the spot when he came back. Mk showed him the pouch flap. Running Wolf read the numbers, then the bearing. He nodded once. He said he would sit on the sand and watch the trail at the same time. One camp, two hunts. Mk walked Running Wolf up the ridge before dark. He lined him up on the three rocks and paced the ten steps north, east, south, west. Running Wolf set his pack down at the center. He said no one would dig here while he drew breath. He did not raise his voice when he said it. Mk went back down to Finn's claim in the last light. His site had a man on it now. His debt still stood at thirteen days. The gecko climbed to his shoulder. Somewhere out on the trail, two travelers were still walking toward a patch of sand that was no longer empty.

Mk swung the pick through the morning. Finn Jarro watched from the shade and marked the hours on a slate. Twelve days left on Running Wolf's watch. Thirteen days left on the debt. Mk needed strangers' names, and no stranger walked past Finn's claim today. He set the pick down and thought about who did hear things. Roma Lyle heard everything that came off the flats. Traders stopped at her hut for water. Mk would send her word. At the water break he asked Finn for one favor. Finn drank from his jug and waited. Mk said he needed a runner for one afternoon, someone to carry a note to Roma's hut and back. Finn spat in the dirt. He said his hired boy could go, but the hours would cost. One day off the runner's own work meant one day added to Mk's count. Fourteen days now. Mk agreed before Finn could smile. The gecko shifted on his wrist. Mk wrote the note on the clean side of a scrap of hide. He asked Roma to listen for men asking about the flats or the dune, and to send names back with the boy. He mentioned Running Bear and Aiyana Redfeather by name. He signed it with the same bearing he had shown Running Wolf. He handed the hide to the runner, a thin boy in a yellow coat named Finn's kin. The boy took the note and went. The afternoon dragged. Mk broke rock and watched the trail. Two riders passed the claim near sundown. One wore a red scarf and rode slow. Mk did not know his face. He marked the scarf in his head and kept digging. The gecko climbed to his collar and stayed there. The boy came back after dark. He had run hard. He handed Mk a folded strip of hide with three names on it in Roma's blocky hand. Slate Pruett, asking after a buried wreck. Rook Galvan, asking after old salvage rights on the dune. A third name smeared by sweat. Roma had drawn a small arrow next to Pruett's name. Below the names she had written one line. Both men had asked which claim Mk worked, and both had walked out past her hut toward the flats before noon. Mk folded the strip into his pouch beside the bearing. He had his intel. He had paid for it with another day on Finn's count. Running Wolf would get two names when the boy carried word up the ridge in the morning. But two men were already on the flats, ahead of the runner, ahead of the news. Mk picked up the pick and drove it into the rock. Fourteen days now, and the dune already had visitors.

Mk swung the pick at first light. Finn Jarro sat in the shade and marked the slate. Fourteen days on the count. Twelve days on Running Wolf's watch. Two men already on the dune, and Mk chained to this rock. He set the pick down and walked to Finn. He asked to buy the day out. Finn drank and shook his head. The debt was hours, not coin. Mk went back to the rock. The gecko clung to his collar and did not move. Mid-morning a rider stopped at the claim. Red scarf, slow horse. Mk knew the scarf from the sundown trail two days back. The man swung down and gave his name as Silas Blackwood. He wanted water. Finn pointed at the jug. Silas drank and watched Mk work. He said he had passed two men on the dune, digging with a short-handled spade. One tall, one thick in the chest. They had asked him where Finn Jarro's claim sat. Silas said he had told them nothing. He said it plain, no smile. Mk asked what he wanted for the news. Silas said he wanted a favor owed, no more, and rode on. Mk stood with the pick in his hand and counted what he had. Two men on his dune with a spade. Running Wolf still climbing. Fourteen days between him and the sightline rocks. He could not leave the claim without burning the sand-scanner deal and every hour he had already paid. He needed a body on the dune today, not tomorrow. He walked back to Finn and asked for the runner boy again. Finn said the boy was gone to town on his own errand. Mk asked who else moved for hire. Finn thought and named one man drinking at the trading post. Wyatt Redstone. Slow, honest, cheap by the hour. One day added to the count for the send. Mk wrote a second strip of hide. He drew the three-rock bearing at the top. He wrote Running Wolf's name and told Wyatt Redstone to ride the ridge trail, find the guard, and put him on the two diggers by dusk. He wrote Slate Pruett and Rook Galvan under the bearing so Running Wolf would know the faces to move on. He gave the strip to Finn and told him to hold it for Wyatt when Wyatt passed through at noon. Finn scratched a fifteenth mark on the slate. Mk picked up the pick. He had bought a hand on the dune without leaving the claim. He had not bought speed. The two men had a spade and half a day's head start, and every swing of Mk's pick was one swing they took at his sand.

Mk swung the pick through the afternoon and watched the sun drop toward the ridge. Noon had passed. Wyatt Redstone had come and gone with the hide strip. That meant the message was moving. It did not mean it had arrived. Finn Jarro sat in the shade and marked nothing new. The gecko shifted on Mk's collar. Mk counted the hours between the claim and the dune and knew he would not sleep tonight without word. An hour before dusk a girl walked in off the flats. Braids, fringed dress, no horse. She stopped at the water jug and drank without asking. Finn watched her over the slate. She turned to Mk and said her name was Aiyana Redfeather. She said she had crossed the dune trail at midday. She had seen two men digging, and a third man come up on them from the ridge. She said the third man wore a braid and carried no rifle. Mk asked what happened. She said the three of them argued, and then the two with the spade rode off north, toward the canyon lands. She said the man with the braid stayed on the dune. Mk set the pick down. He asked if she was sure of the direction. She said north. She said it flat, once. She said she had passed a nomad teepee at the fork and stopped for water there, and an old man at the teepee had told her a rider had come through asking after Finn Jarro's claim, and she had followed that word here. Mk asked what she wanted for the news. She said nothing. She was looking for her grandmother's bundle and the raiders' trail ran north, and she wanted anyone who had seen two men on horses to know she had passed. Mk asked her to describe the two diggers. Tall one, thick one. Short-handled spade. She had it right. He asked about the man with the braid. She said he had shown the diggers something on the ground, drawn in the sand with a stick, and the diggers had spat and mounted up. She did not know what he had drawn. Mk knew. Running Wolf had shown them a hole with nothing under it, or a bearing that did not match theirs, or something else that made the spade not worth the hour. It did not matter which. The diggers had left. Mk gave Aiyana Redfeather a strip of dried meat from his pouch and pointed her north along the ridge trail. She nodded once and went. Finn scratched a mark on the slate for the day. Mk picked the pick back up. Running Wolf held the dune. The diggers were riding away from his sand, not toward it. But they were riding north, toward the canyon lands, and they had seen the hole. Whoever had sent them would hear where the hole was before Mk's debt ran out.
