Olympus is a floating city in the sky with the title "The City in the Sky." It was created by the first and famous pirate Bermuda who was not only a skilled fighter but a genius.
The city has sky trains, where the tracks can also be used for zipline. In the sky there are many blimps but not only blimps, also sky ships, which are controlled by the famous sky pirates. Since this is a city created by the first Pirate, the city is basically pirate territory although any class can visit or live here.
