To avoid being overthrown, you should first assess the reasons that led to the downfall of the villainous emperor in the original novel. Was it because of high taxes? Or was it due to political unrest? Once you figure that out, take the opposite actions. For example, if taxes were high, lower them. Also, try to build a strong support system among the nobles and the common people. Be fair in your judgments and don't abuse your power.
You need to break free from the pre - set path of a villain. Look closely at the events that lead to your downfall in the novel. If it's because of a war with a neighboring kingdom, try to negotiate peace. If it's due to internal unrest caused by your tyranny, start by being more lenient. Reach out to the heroes in the story and explain your new intentions. It might be difficult for them to trust you at first, but consistent good deeds will change their minds. Also, use your power as an emperor to improve the living conditions of your people. This will not only change your fate but also rewrite the story in a more positive light.
You should expect a difficult path. You'll have to constantly assert your authority over the kingdom. There will be economic issues to deal with, like managing the treasury and ensuring the prosperity of the land. Also, there could be external threats from other kingdoms or forces. And don't forget about the moral dilemmas that come with being a 'villainous' emperor. You'll have to make choices that might seem cruel but are necessary to maintain your power.
Well, one challenge could be facing the hatred of the other characters. Since you're the villainous empress, most of the good guys would be against you, making it tough to have allies. Another is dealing with the moral implications of your actions. Even if it's in a novel world, you might struggle with the evil deeds you're supposed to do.
First, you could try to understand the character you've become more deeply. Read the novel carefully to find out the motives and actions of the original villainous empress. Maybe you can find a way to change her fate or at least make her more likable. For example, if she was originally cruel because of past traumas, you could try to heal those traumas in the story's context.
One way is to start making different choices. For example, if the original villainous emperor was cruel to the peasants, you could start implementing policies that are more beneficial to them. This could change the public's perception of you.
One way is to find common ground with the heroes. Instead of always being in opposition, you can work together on some issues that benefit both sides. Also, you can use your power for positive changes in the empire, like improving education or healthcare. This could start to shift your reputation from a villain to a more complex character.
You need to be very careful with your decisions. First, figure out what led to the tragic end in the original story. Was it because of a particular relationship or a political move? Once you know that, you can make different choices. Also, try to build a good reputation among the common people. They can be a powerful force in the novel. If they support you, it will be harder for your enemies to bring you down.
