Recently repaired airship hangar reachable only through the guild until a standalone access point is bought.
Louis points out that the hangar has only just been fixed, and asks whether closing off the saferoom means losing access to it at The Castle; Samantha echoes him. Rosetta answers that they can buy a standalone Hangar Access Point and attach it directly to the castle, which Donut does for five million gold with visible reluctance at Carl's order.
An airship hangar, freshly repaired, normally entered through the guild.
Air asset whose access must be re-bought once the saferoom entrance is destroyed.
