So the character is a sorceress of sorts. Her sister is the queen of the country. While she was away, she got word that a neighboring kingdom is going to attack. She is under the impression the letter arrived safely to the queen. However, when she arrives to her sister's castle, she finds that the message was never delivered and while they try, they don't levy a defense fast enough. This has led to the deaths of the queen's two children and the imprisonment of the queen herself. The sorceress finds the agent responsible for delivering the message, and finds out that instead of seeking an audience with the queen and delivering the message, he entrusts it to a servant where the letter is conveniently "lost." What should she do to this guy? Here are the things that can't happen: 1. The sorceress can't kill the man. It's okay if she wants to. But it would ruin a very critical plot point later in the story to have her kill anyone. 2. She doesn't have time to stand around arguing with this guy. Currently, her sister is headed as a prisoner to the enemy kingdom, and if she hopes to rescue her sister, she can't be wasting more time.
