Given the story about Quaeryt in the earlier years of Lydar and then about the Collegium in the first three books of The Imager Portfolio, it seems that some of the imaging techniques developed by Quaeryt were lost, despite the establishment of the Collegium Imagio. How did this happen, and will you be writing another book that explains this?
I am indeed writing another Imager Portfolio book set roughly midway between the close of Rex Regis and the beginning of Imager. In addition to telling another story about a different character, the book will also shed some light on the questions you raise. Beyond that, I’m not about to say more, since I have a great deal more work to do on the book.
