So, in watching the "Making of TES V: Skyrim" video included in the Collector's Edition, one of the developers states that one of the reasons Skyrim was chosen as the location for TES V was because they had the most developed lore about that province from previous TES games.
I am wondering, does anyone know (or think they know) what province that has NOT yet been explored in a game (other than Arena/ESO) do we now have the most lore about? This excludes Hammerfell, Morrowind, Cyrodiil and Skyrim.
DISCLAIMER: This is not meant to be a TES VI location speculation thread! I am simply wondering which unexplored province NOW has the most developed in-game lore. Obviously, this could indicate where the next game takes place but I don't intend for this thread to speculate on that. This is just an objective question I have been thinking about recently.
Thanks!
