Mittelberg is a locale in the Errant Road free-form role-playing game. It is a small town in Farrel, somewhere northeast of Port Lorrel, on the way to Volkanenborg. It's a rather nondescript little place, the site of a country inn where various adventures have happened, but not much else. As far as is known, it doesn't exist in the Poe-verse.
Nothing is known of its nominal governance, but "official" government in the ER version of Farrel doesn't mean much anyway; the real question is, which of the various mercenary outfits in the country claims it? The answer is the Eisenfaust, a shadowy outfit patterned generally along the lines of the Poe-verse's Gewehr and the arch-rival of the Errant-Road-verse Gewehr. However, Mittelberg is so far out in the boonies that the Eisenfaust doesn't really take much interest in it.
