May be entirely irrelevant… I’ve noticed that some (eg. Light Fingers encampment) route options are unlocked by an option on the storylet alongside the "Chart a course" option that opens the map.
ie. some destinations are chosen via the map (including many Fate locked ones) and are visible even if locked – while others have traditional storylet options which are hidden when locked.
