The Silver City is the highest concentration of Devas in the world. Many Devas enjoy the solitude that the Silver City has to offer. Devas of the Silver City are notoriously unwelcoming and shun any non-Devas.
It is rumored that the Silver City is where Devas resurrect, and this is the reason for their secrecy and xenophobia. While others claim that knowledge is power and the Deva are thought to have amassed one of the largest libraries in history. Some even claim that the collection is so large that most of the books are kept in a magically accessed dimension.
