Chapter 72 The Case Named Earth

The opening was held at local dawn the next morning, in the central hall, with the whole shore party drawn up in a half circle and the vault-racks kindled around them tier upon tier like witnesses. The case stood on its plinth under its column of light, and it had opened for no one in longer than human beings had been a word for anything. The Eldest Gardener approached it first, and laid one moss-grown finger on the seal, and did not press; then it turned its still-water face toward Sira, and inclined it, and she understood. She came forward with the wafer-wrapper's empty sleeve still in her breast pocket where Kael's page had ridden for fifteen months, and she set her own hand beside the gardener's on the seal — keeper and stranger, the combination the lock had apparently waited all its long life to feel — and the case unclenched. It opened like a seed pod. There was no other honest word for it. The outer shell divided along grown lines and the layers within folded back in sequence, each membrane thinner than the last, until the floods looked down into a matrix of cells arranged in rays — spores like gray velvet, grains slender and dark, mosses compressed into living stone, a knot of wood no bigger than a fist that stirred, very slightly, when the warmer air of the hall reached it. Ivo read the telemetry off his sampler with his jaw set like a man carrying something heavy up stairs, and at the cell marked with the oldest label he stopped reading altogether, and stood there, and let the number be true: viable. Viable since before words. Viable now. "Grasses," he said finally, hoarse. "Mosses. Wood. This is a young world's starter kit — the rough draft of everything that ever greened there. Chief Archivist, we're standing in front of Earth's first planting. Before the ships. Before the cities. Before us." He took off his cap, and held it to his chest, and did not put it back on for the rest of the ceremony. "Why now?" Tam asked, because someone had to ask the question children ask and archivists dread. "Why open it tonight and not eighty years ago, or eight hundred?" The Eldest Gardener considered him at tree speed. *"Because opening was never mine to do alone,"* it said. *"A vault is kept against the winter, and a winter without keepers is only weather ending. We tested this sample at every season, as we test all the vaults, and we reported its viability at every season, to no one. You do not plant a stranger's bed while the stranger sleeps. We waited to be asked — or to be answered."* The band tilted toward Sira, and the gold moved in it like fish under ice. *"Your people spent two hundred years learning to answer signals. We have spent longer learning to wait for answers. Between us, the arithmetic finally worked."* Bren stood closest to the open case, arms folded, reading its grown layers the way he read the annual rings of sea ice, and what he said was almost a whisper: "Sealed before your species kept fire. Opened by a boy's file, a girl's ledger, and a road somebody paid for before our sun had planets worth naming. That's the provenance." He looked up at Sira. "Enter it exactly like that. Future readers will think we made it up." Deepest of all the cells, set apart the way the case itself was set apart in the hall, lay a single sheet of crystal. When Sira lifted it the surface filled with light from within, and the image it bore was Earth as the sowers had seen it at the first sowing — young and stormy and swirled green-blue, no cities, no scars, a face before its history — and beneath the image, pressed in the oldest layer of the script, an instruction the lattice rendered gently, as if translating something spoken to a child: *For the winter after the fire. Plant me where I grew.* Tam recorded everything, completely, patiently, and his voice only failed once, on the caption, and he cleared his throat and did it again because completeness was cheaper than selection and the reader yet unborn deserved the sentence twice if need be. Bren asked for one minute before the case was closed, and stood his minute facing the open cells the way he had stood it over Mark Three and over the dead mark in the gulf, attending rather than addressing. Noor was sixteen hundred light-days away, but everyone felt her ledger in the room anyway, and it was Sira who said so: "She'll want the interval data. Every cell. Round nothing off." They sealed the case at dusk-watch, keeper and stranger together again, and as the layers folded shut the fist-sized knot of wood — which had been lying still as an artifact all day — turned slowly over once in its cell, like a sleeper getting comfortable, and went on sleeping. Ivo watched it happen with his mouth open, and then laughed until he had to hold the plinth. "Two hundred million years of patience," he said, wiping his eyes, "and it hears one warm afternoon and rolls over. That's not cargo, Chief Archivist. That's a passenger." That night, aboard the Song, Ivo sowed a pinch of the grains into a tray of his own under the grow-lamps, pressing each seed down with two enormous fingers and more ceremony than he had shown a launching in twenty years. "Earth comes aboard," he told the tray. "You're the first of you to fly since — well. Since ever. Sleep well." The tray sat beside the Proximian moss and the Ross 128 vine and the sea-grain of the Strait, three worlds and a memory now sharing one bed of soil, and if the ship's company noticed that the botanist watered it first from that night on, nobody was small enough to mention it. Departure came on the morning watch. The first garden flushed them out in the great uphill wave that meant *go*, terrace by ring by terrace, and at the crown, beside the spire, the Eldest Gardener stood watching them rise, and its farewell came down the light-link in the completed cadence of the road's whole sentence, altered by exactly one clause: *"Season confirmed. Harvest ready. Tell whoever comes. Come back and tell me."* The Song burned sunward out of the scattered dark, and the porch light of the rim sank astern, and ahead — visible now even to eyes, a blue-white point among coins — the oldest bed turned in the light of its own star, breathing its rows into the night, waiting to be asked. ---
