Translated from the back of the book:'Castle construction: What is the cost of a representative palace? Where are mottes usually erected? How do Tobrians protect themselves from the goblins, weideners from the orcs? How thick are the walls of a donjon basement? What differentiates a castle built on a hill from one built on a tongue of land? Siege and storm: How long does it take sappers to dig under the castle walls? How long do the food supplies of a besieged castle last? What damage does an onager do? What is the design of a siege tower? When does a garrison surrender? Aventurian castles and fortifications: From a thorwalsh Ottaskin and a harbour bastion of the Southern Sea, orcish palisades and Weidener barrage temples to the modern horasian fortress Neu-Oberfels and the heart of rondrian fortification, the Lion Castle of Perricum, you will find more than 20 exemplary aventurian castles and fortifications in this volume full of illustrations, maps and cross sections.' - BoardGameGeek
