Wow! An interesting setting indeed, MF. And there are *so* many directions that characters could choose to go in: guerilla attacks against the Goblins, espionage against the Elves to steal the secrets of the Kremm Amplifiers, searching for the lost human city, and so many more.
Great stuff MF. Even though I'm not really a fan of steampunk or airship fantasy, this has great flavour and I loved the airship mechanics. This would be a fun world to play a campaign in. I exhalt thee!
I would be very pleased to see any more of it that you care to post. I'm not likely to be running anything myself for a while, due to lack of time, energy and players, but it's a nice dark world that has a lot of potential.
