...farming colony. That's what they said was housed in the cylinder early in the century. The largest apple exporter past the asteroid belt. Sometimes you would meet someone who claimed their family used to own a piece of it. Talked like they still did, though someone a generation or two before them sold any rights they had to it and moved to the poleis. This would be followed up with big talk of moving back and settling down - met with polite encouragement - though it was clear they could never wean themselves off of living in the midst of noodle bars, art galleries, and museums. Clear that the only forest bathing they would ever do was beneath the anemic little diorama pieces that were allowed to take root in some of the public parks, bred to survive on the faint light radiating from the newer and more power efficient artificial suns.
One user on a Net imageboard, long defunct, claimed they went there a few years before the docking ports were welded shut to hike the reconstructed section of the Appalachian Trail that, supposedly, circumnavigated the cylinder. They never saw any apples. They did find the only thing there you could call a sort of town. Abandoned, but still with power that trickled in from the nuclear plant. They spent a whole afternoon sitting at a terminal that was still waiting for its connection to the Net to be restored after all these years. Entire directories of messages written but never sent.
