The Floating City is a doomsday weapon handed down from the era of the Arcane Empire.
In fact, even in this age, the Floating City is still one of the big strategic scare weapons.
Rumor has it that during the Arcane Empire, a single Floating City could suppress an entire country.
Though back then, the number of Demigods in each nation was far fewer than it is now.
The advantage of Floating Cities began to weaken from the moment every Legend started owning a demi-plane.
Before, a Floating City couldn't do anything to a Demigod with a demi-plane, but Demigods also couldn't do anything to the Floating City.
The final outcome was that Demigods simply couldn't block the attacks of Floating Cities.
Once war broke out, all land-based countries would become targets.
But at some unknown point, this situation started to change.
The industry's consensus is that the most likely cause was demi-planes being delegated down to be controlled by Legends.
