The Teacher

They smelled his fire before they saw it.

Wood smoke, clean and controlled, rising from somewhere past the next shelf. Kai stopped walking and Tomin stopped beside her and they stood on the trade road in the late afternoon light and looked at each other.

"That's not scrub," Tomin said.

He was right. Scrub smoke was thin and sharp and carried the bite of green wood burning faster than it wanted to. This was deep and slow. Seasoned timber, someone who knew what they were burning and had taken the time to choose it.

Kai listened. The signal ran clean through the stone beneath her feet, east, steady, Mother's call pressing close. No dark in it. No binding. Whoever was ahead had not touched the signal.

"I know that fire," she said.

Tomin looked at her.

She walked.

The shelf dropped into a shallow draw where a seep of water crossed the road and pooled against the eastern bank. He had built the fire in the lee of the bank where the wind couldn't reach it, small and banked with flat stones, a pot of something set on the rocks beside the coals. His staff leaned against the bank. His pack sat open with the careful order of a man who had set and broken camp ten thousand times and knew exactly where everything belonged.

Thuse sat on the ground with his back against the bank and his hands on his knees. He was thinner than she remembered. The lines in his face had deepened and his hair, which had been grey at the temples when he left Donath, was white now. His eyes were the same.

He looked at Kai and then at Tomin and then at the road behind them, measuring the direction they'd come from, reading the story of it in the dust on their clothes and the set of their shoulders and the way Tomin held his weight off his left ankle.

"Two stones," he said.

Kai sat down across the fire from him. Her legs were glad of the rest and she let them be. "How did you know?"

"I felt the second one release. Three days ago. The binding loosened and then it broke, and whoever was holding it pulled east." He looked at her hands. "You walked through it on the foundation."

"Both of them."

Something moved in his face. Not surprise. Recognition, arriving late, catching up to something he had suspected but not confirmed.

"Your mother taught you the foundation."

"No. I found it. In the forest, after the first stone. The signal runs through the roots. Through the soil. I can read it through living things."

Thuse was quiet for a long time. The fire cracked between them. The seep ran its thin line of water across the road and pooled.

"I have been teaching practitioners for three centuries," he said. "No one has found the foundation through living tissue. Through stone, through relay points, through the deep earth. Never through roots."

Kai didn't know what to do with that. She let it sit.

Tomin lowered himself to the ground with his back against the opposite bank and stretched his leg out, the ankle swollen and wrapped. He had not said anything since they'd arrived. His face held the careful stillness of a man listening to two people discuss a language he was still learning.

"Tomin reaches," Kai said. "He found the relay stones before I did. He can feel the foundation through the deep earth, the way you described. He's been reading the signal since before I met him. Rallah taught him."

Thuse looked at Tomin. A long, measured look that traveled from his face to his hands to the swollen ankle and back.

"She told me about you," Thuse said. "Once. Years ago. She said there was a boy in Donath who played Stones of Fate and read the board before his opponents touched it. She said she was teaching him."

Tomin's jaw worked. He looked at the fire.

"She was," he said.

Thuse nodded once. He picked up a flat stone from beside his knee and turned it in his fingers, a habit Kai recognized from Donath, from the long evenings by the Cellar wall when he would talk and his hands would move and the two things would run parallel, his words and his hands working different problems at the same speed.

"I left Donath to walk the relay chain east," Thuse said. "Every stone between here and the source. I've been checking them for binding. Clearing what I could. Some of them I couldn't clear." He set the flat stone down. "The two you walked through were beyond what I could manage alone. I tried the forest stone and the practitioner drove me back."

Kai stared at him. "You couldn't clear them."

"No."

"We did."

"Yes." He looked at her across the fire. "You found a way through that I couldn't find. Foundation through living tissue. Roots, soil, the signal where it grows instead of where it sits. That's a different path than anything I was taught, and I was taught by people who remembered the Garden."

The word landed between them. Garden. He said it with the weight Ace carried when he spoke the names of the dead. Something that existed in a place he could not reach.

"The Garden," Kai said.

"Eden," Thuse said. "East of here. Past the ridge where the relay chain ends. The source of the signal. The place where everything you've been following originates." He paused. "The place your mother went."

Kai's chest tightened. She had been following the call for weeks without naming the destination. She had known it was east and she had known it was the source and she had known her mother was at the end of it, and she had not let herself say the word because saying it would make it a place she might not reach.

"You've been there," she said.

"No." Thuse picked up the flat stone again and held it. "I've stood at the boundary. The Garden does not open for everyone. It opened for your mother. It may open for you."

"May."

"The signal has a keeper," Thuse said. "Someone who tends the place where heaven and earth overlap, where the signal originates. Your mother followed the call there four years ago. She found the source. She became part of it." He set the stone down with a precision that said the conversation was costing him something. "I was her teacher for thirty years and she surpassed me in the first ten. What she became at the Garden, I cannot reach. I stand at the edge and I listen and I know she is there and that is as far as I go."

The fire burned low between them. The seep ran its thin line. The afternoon light sat gold on the stone banks.

"You're sending us," Kai said.

"I'm telling you what's ahead. The decision is yours."

"You're not coming."

Thuse looked east, past the draw, past the shelf, toward whatever lay beyond the horizon where the relay chain ran.

"My work is behind you," he said. "The stones you cleared will not stay clear. The practitioners regroup. The bindings return. Someone has to walk the chain and hold the line open so the signal can run." He looked back at her. "That's my work. It always has been. Yours is ahead."

Kai looked at Tomin. He was watching Thuse with an expression she had not seen from him before. Grief and gratitude running together, impossible to separate.

"Rallah," Tomin said. His voice was rough. "You said she's there. At the Garden."

"She is there," Thuse said. "What she became is there. The person you knew, the person who taught you over a game board, who saw the signal in the way you moved a stone. That person walked into the Garden and did not walk out. What remains is something that was Rallah and is now more than Rallah, and it holds the source open, and it called Kai across a thousand miles of broken country."

Tomin closed his eyes. His hands were flat on the ground beside him, fingers spread, and Kai watched him press his palms into the earth as if he could feel Rallah through the soil from here. He could. They both could. She was everywhere in the signal now, stronger with every mile east.

"I need to tell you what I know before you go further," Thuse said. He sat forward and his voice changed. The teacher's voice, the one she remembered from the ridge above Donath. Precise and unhurried and heavy with things he had carried alone for longer than she could imagine.

"The Garden was failing when your mother reached it," he said. "The source was under assault. Something from the deep dark pressing against the boundary, and the signal needed a keeper. Someone to tend the place where the signal originates. Your mother was the strongest reader I have ever known. She reached the Garden and she understood what it needed, and she did something I don't have a name for."

"She left us," Kai said.

"She held the world together." Thuse's voice did not rise. "The signal that runs through every relay stone, through every root and soil bed you've read, through every practitioner who listens or reaches. That signal originates at the source. Your mother is the reason it still runs."

Kai sat with that. The fire had gone to coals. The afternoon was thinning into evening and the draw held the warmth of the day close, banked against the stone walls.

"The dark practitioners," she said. "The ones binding the stones. They're trying to reach the Garden."

"Yes."

"They're trying to break what my mother holds."

"Yes."

"And you've been walking the chain alone, clearing what you can, holding the line so the signal stays open."

"For four years." He said it the way he said everything. Without drama. A man stating the scope of his work.

Kai looked at her hands. The same hands that had slid beneath the flora leaves in Donath, that had pressed against warm stone on the ridge, that had walked through two bindings on the foundation her mother kept alive.

"What do you need me to do," she said.

"Reach the Garden," Thuse said. "Find what your mother became. The rest I cannot teach you. What happened to her there is beyond what I know. Beyond what anyone alive knows."

Tomin opened his eyes. "I'm going with her."

Thuse looked at him. "I know."

"Not because she needs protection."

"No." Thuse almost smiled. The first time Kai had seen that expression from him in months. "Because Rallah would want you there when Kai finds out what she became."

The evening settled. Thuse poured what was in the pot, a thick broth of tuber and dried grain. They ate. The talk went to practical things. The terrain ahead, the ridge, the valley beyond it. Water sources. The path that Thuse had never walked but had been told about by practitioners who remembered the Garden from before the dark began pressing against it.

When the food was gone and the fire was banked for the night, Thuse stood and put his hands on the stone bank and looked at the sky.

"The cold-season constellation will be overhead in four hours," he said. "The signal will peak at the Garden around the same time. If you leave at first light, you'll reach the ridge by midday. The valley is on the other side."

Kai stood and faced him.

This was the moment. She could feel the gathering before the break, the same pressure she'd felt on the ridge above Donath before the Shake came. Thuse had taught her to listen in a cellar doorway. Taught her to reach on a cold ridge. Named the dark in a dawn that smelled of bread. Walked the relay chain alone for years while she lived in Donath not knowing any of it.

"Thank you," she said, and the words were not enough and she said them anyway.

Thuse put his hand on her shoulder. His grip was strong and his hand was warm and steady. He held her there for three breaths.

"Your mother was the best of us," he said. "You are something I don't have a word for yet."

He let go. He picked up his staff and his pack. He stood on the trade road facing west, the direction Kai and Tomin had come from, the direction of the bound stones and the broken chain and the work that would never be finished.

"Walk the path when you find it," he said. "Don't leave it. The Garden will know you're coming."

He walked west.

Kai watched him go. His staff found the road and his boots found the stone and he moved the way he always moved, steady and unhurried, a man who had been walking longer than anyone alive and intended to keep walking until the world told him to stop.

She watched until the road took him and the evening swallowed the sound of his steps and he was gone.

Tomin stood beside her.

"First light," she said.

"First light."

They banked the fire and slept on opposite sides of the draw, the warm stone at their backs, the signal running east through the ground beneath them, and Kai dreamed of a garden she had never seen, tended by a woman she had lost and was about to find.
