Sanctuary!
Well, I figure I should probably do a little more writing about the stories that I've published. You know, for kicks and such. So here goes...
The city of Sanctuary is where Ezra Hawkins, the protagonist of Wind-Scarred, grew up. They believe that they're the last enclave of humanity on Earth. They're wrong, but that's not important right now.
Sanctuary was birthed from two main ideas. First, every person who was part of the founding of the city was a tenacious genius. They had survived a war with godlike beings and clung to their technology in the face of insurmountable odds and dwindling resources. They were scientists, inventors, and all around really smart and stubborn people. Second, scarcity. All of these people were suddenly isolated from the rest of the world. Sure, they had a peace treaty with the things that had beaten them so long as they didn't venture outside their new city, but that really didn't help put food on their plates. For that matter, after seeing things like San Francisco sink into the ocean (or the bay, take your pick) they didn't have all that much peace of mind.
So based on these ideas, I figured that the people who would rise to power would be the ones who knew how to keep the bad things out and keep the city going.
