"Wow! Look at this, a legendary Zel Deppelin came to your city! And he's in a mood to sell some of his booty. Every 6 hours, he's going to give you gifts and 5 city credits. The trade will last 10 days 8 hours. During this period you'll be able to collect 210 city-credits. Now for only $6.99."
"Zel Deppelin his renowned self has dropped anchor in your town! And he's in a mood to sell some of his booty. Every 6 hours, he's going to give you gifts and 5 city credits."
This unique building can only be purchased for real money during occasional sale events. Every six hours, it gives rewards of city credits and resources; see below the table for details.
These are possible rewards; the reward given is different every six hours when you collect.
After the Zeppelin stops giving rewards, it can be demolished or moved to storage, and the description changes to "This Zeppelin is used by Zel Deppelin, vendor extraordinaire and dealer in things rare and precious. If there's a valuable artifact somewhere, chances are it passed through Zel's hands." At this point the building acts like a normal Entertainment Facility, except that it does not have slots for modules.
