When creating your character you can choose between two major cities, and these are Nedaron Daragon.
In the temple of each of these cities you will find a switch that takes you back to the island's birth, so you can change your city when you want.
Besides the two major cities, there are also cities to be conquered, and those are Northfort Rosendale. To take one of these cities, you need to kill the respective boss of each city.
All cities are at war, and if you enter the territory of an enemy city, you are vulnerable and will receive a white skull, which will come out only after you return to her hometown.
