A day passed. Nothing changed on the island—no human activity, no smart sentry systems, no mechanical vibrations—so it germinated. Roots were first, fractal pipes that branched into the soil looking for minerals. Deep underground, it found a rich seam and spun up molecular printheads to grow atom by atom. Glass blades came next, glittering edges built to cut and stab. Legs followed to produce a crablike form ready to scale walls and scuttle into hiding spaces. Finally, a hair-thin diamond syringe filled with bespoke poison.
