The capital city of the Tavanatalakan Empire. Being at the top of a mountain in a 20-story fortress has attracted kings and nobles from across the continent. They give up their kingdoms, land, and money to live in the heavily fortified walls with fully functioning toilets and medical care... nonexistent in the medieval era.
This also has the side effect of making the mysterious Mountain Emperor immensely rich.
That is why he had the gigantic, helical windmills built. Their power is used to draw water from the great lake into the city, where it flows from aqueducts into homes. During the night, their power is diverted to the Blast furnaces, which turn the hematite reserves of the mountain into steel, so that buildings can continue to get taller.
An interesting side note about Lapin architecture: They are 1/3rd the size of a human, and thus their building stories are 1/3 as tall. But buildings are limited by their construction materials, which is an absolute limit. For reinforced concrete, that is 1 kilometer up. A lapin Architect can fit 3 times as many stories into the same amount of steel as a human can, so buildings can get tall very easily, like how making a small pillow fort is way easier than an adult sized house of pillows.
This also means that the 60 story windmills are actually only 20 stories tall by human standards.
Sidenote, I am taking commissions. But only for people who live on the west side of Las Vegas, Nevada. 20 USD, cash and unlimited time span. I will make no promises with cartoons.
