The Dwarven Folly that is Ruldroc Castle (Patreon)

An exercise in pointless stonecraft, this castle sits abandoned and oft overrun by foul creatures. A dwarven folly – a structure built purely for the sake of building a structure – the castle cuts into and juts over a small canyon in the foothills of Tismar Summit.

When the dwarves left after building the folly, they locked the doors and forgot about it. To this day the front doors remain locked and require Voldrugg’s Key (or magic) to be opened – the current residents got in instead by climbing down on to the bridges over the small river canyon and eventually discovering the mechanisms that open the door on the upper level of the castle.

No one would care about the current residents of the folly if they hadn’t recently gathered a few competing tribes and raided a caravanserai where they looted and burned… and kidnapped the fourth son of Grand Duke Dietmar Stengel. The Grand Duke would really like his son back before they eat him.
