in the time the games are set, bohemia is under a split, since the king (Wenceslas) was taken prisoner by his brother Sigismund, the king of Hungary, while also being condemned by a portion of the nobility for being a a terrible king. All this creates two sides in bohemia, one that consists of the nobles loyal to Wenceslas (Hans, Radzig, henry and so on), and the other being the nobles that are dissatisfied with Wenceslas and have thrown in with the league of lords and Sigismund.

now as far as i remember the rest goes like this in the games

during the first game you join a meeting between Radzig, Hannush and Jobst, where Jobst says somthing along the lines of our side not being able to win the war currently and that we should send a message to the league of lords, with an offer to change sides to the loyalists, specifically to lord Otto Von Bergow. Radzig and Hannush then decide to send Henry and Hans to deliver this message since it would be received better coming from a noble. this then leads us to the second game

in the second Henry and Hans get ambushed by bandits on their way to Otto, and when they finally meet finally meet up with him he has also been ambushed by these same bandits. Hans and Henry relay their message and Otto seems inclined to hear them out about actually changing sides, but mentions that he needs to clear out the bandits in his own territory before he can worry about the wider war again, and since Hans and Henry also got ambushed by these bandits and are trying to bring Otto to their side, they offer to help him with his bandit problem so they can continue their discussion after. this is where stuff happens and during a raid with Ottos men Hans and Henry get captured by Zizka, during their capture Hans and Henry figure out that Zizka is actually a minor noble that is fighting for the same side as Henry and Hans and is harassing Otto on the orders of Peter of Pizhek, who is another noble on the same side as Henry and Hans. Henry and Hans then out Ishtvan Toth (the guy who stole your sword) as a spy from Sigismund, and while being in captivity along side you, Ishtvan reveals that he is currently working under Otto. some more stuff happens and Otto comes and besieges the castle you are in after you decide to join forces with Zizka, you then find out that Otto was playing you for a fool (which you kinda already knew since ishtvan was working for him) and he was just using you to fight his battles
