Game of Thrones: the Brandenburg Eagle

In 1437, the Holy Roman Empire was in turmoil. Emperor Sigismund was about to die. The competition for the throne stirred up the whole of Germany. It has only been more than twenty years since the Hohenzollern family took over the Elector of Brandenburg, and this land full of swamps and forests is still full of undercurrents. Foreign rulers could not get the sincere loyalty of the local nobles. Rebellions, private wars, and urban rebellions occurred one after another. The northern Teutonic Knights, Poland, and Pomerania were surrounded by powerful enemies. The old elector Frederick I was aging, and he originally hoped that his eldest son, John, would take charge of the country. But John was obsessed with academics and incompetent in governance, and the situation in Brandenburg was on the verge of getting out of control. The second son, Frederick Tieya, went to Poland when he was young and lived in a foreign land for more than ten years. He was deeply immersed in Polish culture and almost became a Pole. When the family crisis came, he was urgently recalled to his hometown. He has an iron-blooded will honed on the battlefield, but he is very unfamiliar with his hometown of Brandenburg. The legal inheritance belongs to the elder brother, and the force and determination that can maintain the existence of the state are tied to him. The suspicions of local nobles, the power struggles between brothers, the torn identities between Germany and Poland, and the treacherous alliances and conspiracies between princes. The returning eagle must fight for a way out for the Hohenzollern eagle flag in the whirlpool of power in his homeland.
