Elias had never married, a fact Thomas had noticed without ever quite raising it, and it was Aldith, of all people, who finally asked him about it directly one evening at the tally-bench, the whole council gathered late over a shared meal after a long day's work on the rail line's extension.
"You've mapped every road in this March," she said. "Surveyed every ridge, charted every trade route worth knowing. I've never once heard you mention a wife, or a sweetheart, or any particular person waiting for you at the end of a long survey."
Elias considered the question with his usual careful precision, turning it over the way he turned over any problem before answering. "I have never found the right shape for it, I think. Wat had his wife, once, and lost her, and built a life around the loss. Diccon found Elsbeth, and built a life around finding her. I have spent my own life mapping the spaces between things — the distance from here to Oakhaven, the sightline from one tower to the next. I do not know how to map the distance between two people properly. I suspect that is why I have never tried."
"That's a rather sad way to live, Elias," Aldith said gently.
"Perhaps. I do not experience it as sadness, though I understand it might look that way from outside." He set down his cup, considering the question further with the same honest thoroughness he brought to everything. "I find I am happiest at the top of a tower, watching a sightline resolve properly after weeks of careful calculation, or tracing a new road's grade until it finally makes sense on the page. I do not think that makes me incomplete. I think it simply makes me a different shape of person than Wat, or Diccon, or any of the rest of you."
Victoria, listening with her usual sharp attention, offered the observation that seemed to land somewhere Aldith's gentler concern hadn't quite reached. "You've built something rather remarkable with that solitude, Elias. This whole valley sees further because you've spent your life learning to see clearly on your own. I don't think that's a lesser kind of life. I think it's simply one this valley happened to need rather badly, and got lucky enough to find in you."
Something in Elias's flat, careful composure warmed, briefly, at that. "I have never thought of it in quite those terms. Thank you, Victoria. I find that considerably more comforting than Aldith's sympathy, if she'll forgive me for saying so."
"I'll forgive you," Aldith said, laughing despite herself. "Though I reserve the right to keep worrying about you regardless. It's rather my whole trade, worrying about people whether they've asked me to or not."
The conversation drifted on to other matters, the rail line's progress, the fever house's continued watch, and Thomas found himself, walking home with Victoria under a clear autumn sky, turning Elias's quiet contentment over in his own thoughts.
"I used to think everyone needed what we have," he said. "The partnership, the marriage, someone to hold onto when the falling number gets too heavy to carry alone. I don't think that's actually true, watching Elias tonight. I think some people build their whole meaning out of something else entirely, and it's just as complete a life as ours, in its own different shape."
"I think that's exactly right," Victoria said. "I used to worry about him too, the way Aldith does. I've stopped, mostly, because I've watched him climb that near tower a hundred times now, and every single time, he comes down looking like a man who's just finished something that mattered to him completely. That's not loneliness, Thomas. That's simply a different kind of full life than the one we happened to choose."
They walked the rest of the way home in comfortable silence, the towers' small lights burning steady on the ridge behind them, and Thomas thought, watching them, that Elias himself was very likely up there even now, tracing some new sightline in the dark, entirely content in the particular solitude that had built, alongside everything else, the whole careful architecture keeping this valley connected to the wider world.
