I am hesitant to call this a future of either the DV or Codex Alera. The best connection that I can see would be that the Vord show up at some point.
I tend to think that the world of Cinder Spires is a far future Earth, with Spire Albion being located somewhere in England, the Olympians being somewhere in Greece, let's say London and Athens as a guess. Spire Aurora would be somewhere in the Arctic Circle, maybe.
Now is this the same earth that the DV is in? At this point, who knows? Maybe the planet is like it is because of the events in the BAT. Maybe the side effects of being a magic user have once again changed to causing madness in all who attempt it. Maybe the first gen power crystals are some of the baddies imprisoned in crystal on DR
I don't know if it will ever be explicitly stated, but that is what makes for the best crazy theories.
