A good story conveys deep tension. So, if you have a great hero, like Sherlock Holmes, you might balance him with great evil. Otherwise, Holmes and the reader get bored.
We are embarked on a journey to create a story about games of power. And what tension holds the story together? By definition, it must be lack of power. Perhaps a weak character craving power and striving to achieve it. Perhaps a powerful character who loathes what has obtained.
At the core of the above examples is a dilemma. As humans we crave knowing the answers to questions. We believe in knowledge as power. But strangely, we get bored with these answers nearly as soon as we discover them.
So our weak character is not bored, and perhaps our powerful character is troubled by intense depression.
Perhaps. BTW, if this interests you, consider how Sir Arthur Conan Doyle created and used the character Sherlock Holmes. Doyle was not happy with Holmes. People loved the character more than the creator of the character. And Doyle knew that he achieved the creation using a cheap parlor trick.
