Octavius's Arc

Chapter 2 of 2

At dawn Octavius returned to the pond with a plan. He had chased the moonpetal his whole life and lost one halfway open last season. He would not lose another to warm water and thin pressure. Today he would build the trench inside his garden. He dug beside the swirling blue water until his tentacles ached. Petals drifted down into the hole as he worked. When the pit was deep enough, he lined it with flat stones and fitted a translucent coral shell over the top. The shell had ridges like ribs and a small round window in front. He had traded three seasons of kelp harvest for it. A craftsman told him the seams could hold pressure if he weighed the dome down and pumped cold pond water through the base. Octavius sealed the seams with wax from the sea-bees. He stacked stones on the ridges until the dome creaked. Then he draped dark kelp fronds over the whole structure so no light could reach the chamber inside. The fronds hung in long strands and swallowed the shape of the dome completely. He slipped a pressure stone through the window and watched the needle. It climbed. It climbed further. He held his breath through his siphon. The needle stopped far short of trench weight and would not move again, no matter how many stones he piled on the ridges. He tried anyway. He fetched the seedling from its jar and pushed it through the window into the cold, dark chamber. He sealed the window. He waited a full day beside the dome with one tentacle pressed to the coral. On the second morning he heard a soft crack. He lifted a kelp frond and looked through the window. A seam had split along the base. Cold water had drained out. The seedling lay on the stones, gray at the edges, curled like a closed fist. It had not even tried to open. Octavius sat with the dead seedling in his arms for a long time. The dome had failed. The kelp canopy had failed. His whole method had failed. He understood now, with a flat certainty, that stacking stones would never be enough. The bloom knew the difference. It always would. He carried the seedling back to the pond and buried it under the wildflowers. Then he lifted the coral dome off the pit and set it aside. He would not use it again. Whatever came next would not be a copy of the trench. It would have to be something else, something the bloom might accept as its own. He did not know yet what that could be. He only knew he had to stop pretending stones could weigh as much as the sea.
