Wallachia

The term Wallachia in Castlevania is oftentimes not only used as the proper region - just "outside" of central Europe behind the Carpatian Mountains -, but also as a fictional term for the realm of Dracula, or the region of Transsylvania. In contemporary German, the "Wallachei" still is in use as a term for behind the horizon - analog to it's historical counterpart where people would neither speak Latin nor German. The end of the medieval world.
