The Albert City Hall was located right beside the Magic Union Branch, and it was even busier than the Magic Union Branch.
The reason for the popularity of this or any City Hall was because, in the Magic Union, these City Halls serve two important purposes.
First, the City Hall controlled the dimension gates under a city which means they had full control over who entered the dimension gates and when. They issued a Dimension Entry Pass (DEP) of three levels, Bronze, Silver, and Gold.
Each DEP represents a different time period one can spend in a dimension in the cities of three regions.
In the Outer Region, third-grade cities, Bronze level DEP would last three days, Silver level DEP would last seven days, and Gold DEP would last ten days.
Everyone took the DEP seriously because the magic union has absolute laws instated upon the violation of these DEPs.
