Hamster, thank you for the tip, it helped.
I will write a post tomorrow (at the moment it's almost midnight here), Shorus will figure out how the trebuchet works and make it usable, he will also explain how to destroy it quickly during battle. I will try to make his experiments with the trebuchet as funny and amusing as possible :)
About killing the Prince's younger brother, it will take some convincing, after all Shorus is a kind hearted fellow.
