Castles in the Sky was the first time I tried to play in someone else's playground. The first half of the piece is a historic, mechanical and trade-based approach to dealing with what is, essentially, flying steamer container ships in a fantasy world. I ended up basing it more on early Portuguese Age of Sail.
A couple of outtake comments on this:
1. I hope I didn't step on too many toes.
2. On reflection, I don't like the take of manufacturing in flight. It's too big of a space to profit trade off. People take space and resources to maintain, and workspace is enormous. No one historically does this for an excellent reason. Every square foot given up to making things is some multiplier loss. But in a fantasy world, YMMV.
3. Huge flying container ships radically change the nature of a fantasy worlds. Instead of being ruthlessly local, it becomes multi-cultural and global. This is good and bad but opens some interesting doors.
4. The expense of the flying castles combined with the potential huge profits would pressure inventions of advanced capital markets (insurance, investments) but I didn't want to go there because it starts to strip the world of its fantasy flavor.
Anyway, please enjoy! And it's open question season today! #dungeonsanddragons #economics #gaming
