The PCs are at the border on their way into a new kingdom. Shortly after the border, or just before it, they are contacted by a man who claims he is a nobleman and he needs their help. This is the story he tells them. "For some years ago this country was a happy country. There were peace and the people were well fed. Everybody was happy and it was a healthy kingdom. But there was a snake in the paradise: Duke Foo (Call him something that's would make sense depending on your world). He had an eager longing for the crown and for three years ago he took it with the help of foreign help. The old king, and some of the noblemen who where loyal to him [the man lowers his head in a gesture that means that he's on of them], were send in exile. The kingdom was sent into terror. People with opinions which didn't please the king where killed. Good men and women where tortured and killed for the sheer pleasure of the king. The once happy nation was now a frightened country! For two and a half years the rightful king has been abroad but never, never, lost faith in once again come back and making justice! I am sent forward to make sure that the rightful king can enter his castle safely and it is in that task I need your help. I need your help to assassinate the pretender-king!" The PCs get some extra details (like a map of the castle) and afterwards the sets off onto their task of justice. How far they comes before they discover the truth is up to you but they should get the chance of really, really screwing things up. The truth is: the nobleman was lying. For some years ago the country was not happy, it was in terror -the terror of the king. After a while one of the noblemen was sickened by it and created a revolution and put himself in the throne. The new king is not a good king but his intentions are good. He wants to put things right and to make the country a happy nation. He has succeeded in some parts and the people love him (they will love anyone who threw out the old king). The old king was send into exile together with some noblemen. That part of the story is correct, the fake part is the parts where the government of each king is described. What the PCs now are going to do is to kill the good king and to reinstall the evil one. Nice plans eh? Just watch out when you tell the players the truth. They might be angry... ;-) Well, I think they should have a fair chance of discover the truth themselves, before everything goes out of hand. But if they overlook the evidence.... Make them suffer...
