The area where Passage City is located is a large grassy plain. North of it is the Starmud Forest, and south of it is the Turtlelake Forest.
And the empire is to the west while the Undrasil Kingdom is to the east. Because of this, the carriages and caravans are funneled to this city. Thus, resulting in its current economic growth.
The city is much closer to the Turtlelake Forest to the south, so Clova landed in that forest. They then entered through the south gate of the city.
Once inside, it was evident that it was a wealthy city. The streets are wide. At least two carriages can go through each direction. For a city in this world, that was already double than average.
Many goods were carried in the carriages, and there were large parking lots for the carriages to stop. There were pubs everywhere, and most of the people they saw were mages and swordsmen, surrounding a merchant.
