A wandering ark evolves into a mobile civilization and shipyard that constructs more vessels while en route. The narrative follows choices of destinations, long sublight voyages, and infrastructure like laser pusher and braking arrays. It explores onboard governance, industrial self-sufficiency, and how a fleet maintains cohesion, builds habitats in transit, and prepares contingencies before arrival.

A massive interstellar ark morphs into a roaming civilization and mobile shipyard. Century-long transit life reshapes governance, crew dynamics, and demographics. In-transit engineering spawns new vessels, habitat manufacturing, and forward-deployed braking systems. Modules, tenders, and cultural ties coalesce into a true moving armada.
