Everything I have heard, this is likely not a Codex Alera setting. Or if it is, it is so far removed from that timefrae as to be something altogether different. It would seem odd to me that Furies now only manifest in manufactured crystals, when they used to just manifest by nature? It may be revealed later on that this is in fact Alera, but I would be skeptical until Jim has outright stated either in-universe, or by interview.
With regards to the Vord, keep in mind that Alera was not the first place they have been.
