The Eclipse
The Eclipse is one of the, if not the, most expensive airships ever made. The luxury airship was engineered by some of the greatest and brightest minds in Mithra, both man and mal, costing as much as a small castle. Maybe even a medium-sized castle. It was commissioned and funded by Senator Baerengar who uses it as his own personal "pleasure barge" as well as to carry around important people for meetings or business deals.
What you have so far sounds interesting, I'd like to know more about it. The map looks cool too, I look forward to seeing some labels and pins on it.
