The Urbanites are people who had power and influence in the old world, they buried themselves in bunkers to remain pure when the cataclysm hit the world...and even now they keep a distance from the lowly survivors who have become impure through their contact with spirits and their lack of old technologies.
This new character is one of the young urbanites, someone who wants to see the world outside for themselves. Some might be slumming it, others might be rebelling against their parents, and a few might be legitimate scholars trying to understand the truth beyond their glass and steel domes.
This character probably has errors in it and needs some more work...it's just after 3 in the morning as I write this. But sometimes you just need to get the ideas out...so here it is.
