Shipwright

The Shipwright is one of the 5 possible Buildings that can spawn on every Island.

It is used to buy bigger and better Airships. The newly-bought Airship will have 50% Energy. Buying a new Airship will transfer the Modules, but not the Crew. Airships can also be purchased and sent to the nearest Caravan Office with available Airship slots where they can embark on Caravan Routes.

Not all Shipwrights will have every Airship.

Shipwrights offer a 4-part delivery Questline that reduces the Airship prices globally by 15% halfway and 30% on completion.

The island where the player starts will always have a Shipwright selling Boat and Pink.

The Shipwright will always be the last Building on an Island.
