This has been a very fascinating read. I enjoyed the meta and worldbuilding you've created for the time before Caspian X became King. History does change over time and it's interesting to see that Caspian I wasn't actually a Conqueror as the stories claim, nor did the original Telmarines paint Narnian past (in particular the reign of the High King) in a bad light.

I also enjoyed the present setting, with a "modern" Narnia that has universities and enjoy reading of a blind King who has a "guide dog" of sorts as well. :-)
