Apadayan is a city constantly being built. Long ago, when the city was first constructed, its citizens noticed that the buildings were slowly sinking into the ground. In a panicked response, they built their buildings higher and higher to account for the height lost to the earth. However, as more materials were added to their city, the faster they sank. So the city's engineers found a way to convert the friction caused by the sinking city into energy for more effective construction. Therefore, it is absolutely necessary for Apadayan's construction to accelerate at the same rate as the city itself. Today, it is said that the rate is so fast that you can look out at the horizon and feel yourself setting with the sun.
