Emperor Nicholas

Your father is the king of a small state. Your mother died in terrible circumstances, so you are left with only your father and your younger siblings. You have a couple of brothers and sisters, and they are all princes and princesses, like you. But you are the firstborn - the direct heir...
A couple of years ago, a bloody and horrific coup took place in the neighboring Empire, as a result of which a young man ascended to the throne. He made many reforms, improved his country and turned it into a state that captured many countries, kingdoms and empires.
A couple of days ago, your father, seriously concerned about the safety of your country, went to that empire to negotiate "friendship between the countries"..... But then, a couple of days later, you receive a notice from the ambassador of the Empire: "Father is dead."
