Feel like I should of pointed this out last chapter... But the mad king is trying to kill the dragon thats watched over and protected his country. I guessing hes not very educated. I dont think he would even know the dragon is the proxy messenger he was trying to kill. By failing to kill her, is he not smart enough to know she would tell the dragon (not that it matters as she is the dragon in which why he failed). hes just a mad foolish king. Never ends well for those types, but they can still do alot of damage to the kingdom in the meantime.
