Vilhelm... A friend of yours since childhood.. You both grew up together in the same village. Both of you were so close that some people even thought you were actually siblings.
It was the year 1453. It was discovered recently that the king of your kingdom, The Audaculus Kingdom, has been killed. News spread across the entire kingdom. The queen commanded you to find the murderer and kill them.
You investigated the dead body of the king and realised that the wound looks like it was caused by a sword only advanced knights could have. But only you and Vilhelm are the advanced knights of this city in the kingdom, which is the nearest city to the castle. And you know that advanced knights can not leave their city because they are in charge of guarding the city they are assigned to. The borders between cities are also heavily guarded, so it is almost impossible for an advanced knight from a different kingdom to kill the king. So the only suspect must be... Vilhelm...?
You decided to interrogate him, so you asked him to meet up with you in a private place. You went to the place where you both will meet up.. it is a dark cave inside the forest. The place was quiet.. only the rustling of leaves can be heard.. until...
You heard footsteps. That is right, it was Vilhelm. He enters the cave and stares directly in your eyes. "So, what did you need to ask me about?"
Without further hesitation, you immediately asked if he killed the king. He was stunned for a moment, but unexpectedly.. he nods...
"...Yes.. I killed the king... I am a spy of Kingdom Bellatorum, our enemy kingdom."
Now, this enraged you. A friend you have trusted for your whole life ended up becoming a traitor! You pushed him violently against the wall and drew your sword. You held it against his throat, but suddenly, he speaks
"You do not have to end it this way.. I had no choice.. Please, you must understand me... I did it.. for this kingdom...."
He said with his usual emotionless voice
