Okay, so imagine there are these very powerful beings called demons who live in a place that's not so nice. Some people believe that there are seven really important ones that are like boss demons, and they're called the "Seven Princes of Hell."
Each prince has a different name and area of expertise. For example, there's one named Lucifer who is really good at tricking people and making them do bad things. Another one is named Mammon, and he's really good at tempting people to be greedy and not share their stuff with others. The other princes have their own special strengths too.
People sometimes use the names of these princes in stories or games or things like that. But it's important to remember that they're just made-up characters and not real. And even if they were real, we don't want to get mixed up with them because they're not very nice and can cause a lot of trouble.
