While the Royal Guard fulfilled the training fights in one of the polygons, their kingdom was attacked by the natives and now the King himself has to keep the defense. The king stands on the highest tower of the kingdom and looks around its borders to prevent a surprise attack, and even at this time it strengthens its bastion, to adequately reflect the attack. Take part in the defense of the king, and you are building a tower on a strategic plan and a bow shooting enemy soldiers.
