Your choice of hometown will greatly affect the sort of abilities you have and the sort of career you can plan for yourself in the game. Generally speaking, ancient and legendary areas have more of a magical flavor and more talents (legendary more so), and areas where the people lived close to nature would be likely to produce good healers. People born in industrial times would be best suited to the use of technologically advanced weapons. More hometown choices will be added as new areas are created.

You can change your citizenship by going through one of the hometowns' citizenship quests. These quests are costly in experience, 37.5 million to be exact. It also requires that you have a total of 47.5 million experience. With that, you are also charged 100k gold during the quest. And they do require a good amount of work to complete. Once you've completed the quest, your skills and/or spells will be completely wiped and you will be able to then relearn skills for your new hometown. Those under level 11 can do these quests without cost. The quests for London, Arabia, Tara, Kleinstadt, and San Francisco are completed. Lima is underway.
