He was going to be diplomatic about this one.
The outhouse was fifty feet from the back door. In summer this was inconvenient. In winter, when the wind came off the Veiling Forest and the ground froze hard enough to ring underfoot, it was one of the more unpleasant features of daily farm life, and he had watched his mother make that walk on enough cold mornings to have developed a strong opinion about it.
The toilet required the most technical work of anything he had built so far. Not the seat or the housing — those were straightforward stone-shaping. The complexity was in the waste management: he needed water for flushing, a seal to prevent the smell from coming back up, and an outflow system that handled the waste hygienically without contaminating the water table or the fields.
He solved it with three mana stones and a clay drainage system that ran to a sealed pit at the far edge of the property, lined with purification stones that broke down the waste continuously. The flush was a small water-draw stone in the cistern above the seat, activated by a simple lever. The seal was a water trap built into the drain pipe, the same principle as a proper plumbing system — he had, in his previous life, vaguely understood how toilets worked, and it turned out vaguely was sufficient when you had earth magic and enough time to think it through.
He built it in the small room beside the bathhouse so the two installations shared a wall and the drainage could run through the same buried pipe system.
He showed his sisters first.
Clara stared at it. She looked at the lever. She looked at the seat. She looked at Arthur.
'Is this what I think it is?'
'Yes.'
'You built us a proper toilet.'
'With a flush. And it stays clean by itself.'
Clara put both hands on Arthur's shoulders, looked him directly in the eyes, and said with complete sincerity: 'This is the best thing you have ever done.'
'Better than the heating system?'
'Significantly better than the heating system.'
Lyra, behind her, was nodding.
Saya tried it and reported that it was extremely good and that her tribe was going to want to know about this, which Arthur noted and filed under: things to think about carefully before sharing widely.

The stove was for his mother, specifically.
He had been watching her cook over the farmhouse hearth his entire life — the management of heat that required constant attention, moving pots to hotter or cooler positions over the fire, the problem of too-hot and not-hot-enough and the specific frustration of trying to maintain a steady simmer while the fire did what fires did. He had also, in his previous life, cooked occasionally over an induction stove and understood in a theoretical way what having precise and controllable heat meant for food.
The design was simple: a flat stone slab, smooth and level, with six mana stones embedded in its surface at regular intervals. Each stone was tuned to emit heat upward and only upward, precisely, in a circle corresponding to the base of a pot or pan. Each one had its own control, a small embedded dial of compressed crystal that could be turned to adjust the output from a low warm simmer to a rolling boil. The stones drew from ambient mana the way the bathhouse stones did, refilling themselves between uses.
He built the slab on the prepared stone base where the old hearth had stood, setting the new surface level and smooth and connecting the ambient draw channels through the floor.
He spent an extra afternoon on the controls, making them easy to read by feel — the crystal dials turned in a way that gave clear resistance at each setting, so you could tell where you were without looking. He had watched his mother cook enough to know that looking down at the controls while managing three pots was not a luxury she usually had.
He finished it on a Tuesday and told his mother on Wednesday morning.

She stood in front of it for a long moment.
He explained the dials. She turned one slowly, feeling the resistance at each position. She held her hand above the surface and felt the heat rising from the stone beneath — clean and direct and controllable, no smoke, no flame, just warmth going exactly where it was aimed.
'The heat holds steady?' she said.
'It doesn't fluctuate. You set it and it stays there.'
'No tending?'
'No tending. The stones manage themselves.'
She pressed her lips together in the way she did when she was containing a reaction she thought was too large for the occasion.
'Arthur,' she said.
'Mom.'
'This is — ' She stopped. Started again. 'Do you have any idea how much time I spend managing the fire when I'm cooking?'
'I have a rough estimate, yes. That's why I built it.'
She put one hand on top of the slab and stood there for a moment, feeling it, and her face had the expression she wore when something had landed in the place where she kept things she was genuinely glad of.
Then she turned around and put her arms around him and held on for a moment, and he let her, because that was what you did.
'Thank you,' she said, quietly, into the top of his head.
'You cook for six people every day,' he said. 'It should be easier than it is.'

The family assembled that evening, which happened naturally — the new stove had produced a better dinner than usual because the heat had been exactly right throughout, and everyone had noticed, and nobody had left the table afterward.
His mother looked around at them all.
'These things,' she said, 'do not leave this property.'
'Obviously,' Clara said.
'I want to be specific about obviously. No mentioning the bath to anyone in the village. No mentioning the toilet. No mentioning the heating or the stove.' She looked at each of them in turn. 'If people ask why we seem comfortable, we say the farm has been doing well.'
'The farm has been doing well,' Thomas said.
'It has. That helps.' Mira folded her hands on the table. 'What Arthur has made is years — decades — ahead of what anyone in this country has seen. If word got out about any of it, people would want to know where it came from. And then they would want to know who made it. And then we would have the same problem we would have had if the assessor's stone had lit up.'
The table was quiet.
'I got carried away,' Arthur said.
'You did,' his mother agreed. 'And every single thing you made is wonderful and we are all very glad you did.'
'The toilet alone was worth it,' Clara said.
'Clara,' Mira said.
'I'm being sincere.'
Saya, who had been listening with her ears forward in the attentive way she had, said: 'My tribe would say the bath was worth it. We believe bathing is important.'
'Your tribe would be right,' Mira said. 'The point stands. We keep this between us.'
Arthur looked at the table. He looked at the new stove behind his mother, already cooled down but sitting there with the quiet solidity of something that was going to make a significant difference to a great many Tuesday and Thursday mornings.
'I'll be more careful,' he said.
'Don't be more careful,' his father said, from the end of the table, in the tone he used when he had been thinking something and had decided it was the right time to say it. 'Be thoughtful. Those are different things. Careful means not doing it. Thoughtful means knowing what you're doing and why.'
He looked at Arthur.
'You knew why,' he said. 'Every single one of these things — you knew why. Don't stop knowing why. Just remember that knowing why isn't the same as it being safe to show.'
Arthur held his father's gaze for a moment.
'Yes,' he said.
Edric picked up his cup.
'Good dinner tonight,' he said, to no one in particular. 'The sauce was better.'
Mira looked at her new stove over her shoulder with the expression of someone confirming a hypothesis. She turned back to the table.
'It really was,' she agreed.
