Airplane Suggestion
How about having a NPC around pront that is collecting fundings to build the Airship? Something simmilar to what the brave warrior does.
I mean, it's a good roleplay thing to have around and, putting some realistic milestone, after reaching the necessary funding, we would have the ariship working in a certain period of time.
This is a RAW idea, spoke about it in main chat with some players and decided to open it to get a better elaboration.
Cheers!
