Elara was a Tender, one of a thousand humans who still had a job. Most people simply lived, their needs met by the Tube’s quiet providence. But Tenders walked the maintenance spines—the narrow, warm passageways that ran between the outer shell and the inner habitation layer. They listened.

The map showed a branching tunnel, labeled not in the standard coordinate system, but in a dead language: Uterus Primus .
