More than that, how can the empire rami use their powers at the castle siege?
Page 20 shows it clearly into the papacy range, so are all rami powered by any tower/big tower? (if it is that, why attacking kingdoms in between instead of entering the range with a ship? Chapter 2 shows the papacy has enemy ships literally at their capital walls, so what prevents the empire to transporting the garland ramus the same way into the range?)
