A thought crossed my mind regarding Cadiz
It isn't Valencian, if Valencia is based off of Italy then Cadiz isn't Italian
Every Italian word has to end in a vowel(I speak the language) sure we some natives in Valencia that have names ending consonants but I don't recognise those names.
After all we are only ever told that Cadiz is a stronghold of Kane's power so who knows it probably isn't even in Valencia
