Old Friends Are the Best

An ancient silicon-based organism, surviving on the moon by a centennial pulse, is uncovered after lunar settlements expand. An engineer retrieves a fossil and a botanist brings a fragment to Earth, where the living tissue reactivates. Planted in a garden and tended, the organism sheds its silicate supports, becomes softer and green, and alters its physiology to draw terrestrial minerals, especially iron, while faint memories of a former, fuller existence influence its slow responses. The narrative explores adaptation, unexpected encounters between human science and alien life, and the quiet persistence of unusual biological time scales.
