Thren Valis's Arc

Chapter 1 of 18

Thren Valis had three weeks of food left and no ship that could grow itself. She stood inside her greenhouse, a living dome of curved leaves and translucent panes she had grown from Sporis seed. Her blue hands were stained green from the soil. She meant to build a vessel from this planet's plants, a hull that mended its own wounds and pulled her home. But first she had to solve one problem. She did not know which native plant could bind living tissue into a solid shell. Six pools lined the greenhouse in neat rows, each a shallow bowl grown from woven root. In each floated a different candidate. A purple stalk. An orange-veined leaf. A pale coiling fern. Thren had grown them side by side to test which one fused fastest. But testing was slow. Each plant needed days to react, and she had already lost weeks on two failures. Choosing wrong again would cost her a month she could not spare. She crouched by the pools and pressed her thumb against each stem. All felt ordinary. None showed the knitting she needed. Frustration tightened her jaw. Guessing was not engineering. She needed proof of what already worked. Then she remembered the shape hanging above the far pool. Weeks ago she had cut a sample from the forest, a dense cluster of overlapping leaf-plates fused into hard panels, bound by living fiber. She had hung it to dry and forgotten it. She stood and lifted it down. The plates did not peel apart. Something had welded them into a single shield. Thren carried it to her worktable and cut into the binding. Sap oozed out, thick and amber. But the sap was not the binder. Inside the fibers she found tunnels, and inside the tunnels a beetle, its carapace clear and glowing with green veins. She had seen these beetles feeding on rot. She had never seen one build. The insect chewed the leaf edges, then wept the amber sap, and the two together set as hard as bark. Her breath caught. The binder was not a plant at all. It was the plant and the beetle working as one. No single candidate in her pools could ever have worked, because she had been testing half a system. Thren swept the fern and the purple stalk aside. She lifted the fused sample and set it in the center pool. Then she went to the greenhouse wall, where more of the glowing beetles crawled among her vines, and she began to gather them. She had her answer, and it was worse than she hoped. She could not simply grow a hull. She had to keep a colony of living insects alive inside her ship, feeding, breeding, and building without pause. Her vessel would need to be a hive as much as a hull. Thren looked at the beetle in her palm and understood her real work had just begun.
