One of the biggest things I continued to work on in regards to Fei’s world was the way in which Devils operated in the world. In the universe of Kill Six Billion Demons, devils are subdivided into specific tiers based on the colors of their masks, and tend to aspire to cast off their extra names in order to find their true, most powerful ebon name. On the other hand, one of the main themes I was baking into the worldbuilding was that the EASF did not give a solitary fuck about the established “rules” of the wheel, and thus instead of treating devils as devious imps with which to bargain with, they instead integrated them into society as the equivalents to artificialy intelligent constructs. They still work on the same principles, but with slightly different implementation.
