After the last Corean Chronicles book with Alucius, what happens to all the structures created by the Ifrits? Will there be more books about what follows with all those characters?

The structures remain… at least they don’t vanish instantly, or in the immediate future. Currently, I’m deeply involved in writing other books, and I haven’t decided whether there will be more Corean Chronicles books, and if so, in what time period they will be set.
