Falcon Castle, built upon a mountain near the small town of Hexingen, about 64 kilometers from Stuttgart.
All the castles in this world were not initially established to withstand wars—the blast from a rocket artillery barrage could level not just castles, but even solid concrete blocks.
In fact, most of these castles were fundamentally built between the First Epoch and the Third Epoch, with the purpose of preventing attacks by Extraordinary Creatures from the surrounding wild territories.
For example, the Ancient Solomon Republic of the Third Epoch, while expanding northward from the Italian peninsula, constructed a large number of military and civilian fortresses, embedding them like nails into the territories of the Barbarians and Extraordinary Creatures.
