America was hit pretty hard by the realms, but with the sheer concentration of gifted humans in the major cities, most of them were able to remain.

 

San Fransisco, New York, Las Angeles, Las Vegas and New Orleans are among the cities who are doing the best job of reclaiming the city from the influence of the realms.

 

When the realms collapsed on the human world, they did so in a haphazard matter. The effect is a water-color like separation of the land among the areas of realm influence.
