Overview
The crews at Belis Corona see what service near the Eye does to a warship. Repair work begins around damage that has to be examined before anyone can safely touch it. Quarantine stations process arrivals while the depots prepare ammunition for ships already cleared to leave.
Battlefleet Obscurus needs the anchorage through each new crisis on the Cadian approaches. The loss of Cadia does not remove that need. Beyond the Great Rift, keeping a yard operational can determine whether a damaged vessel fights again or becomes a permanent berth for a crew that cannot get home.
