Rukelion's rant didn't stop the king's wails of anguish. He couldn't handle it.
"Stop it. STOP IT! SHUT UP!" he bellowed as he turned the bunker into a raging inferno. The fire was fueled by his rage and grief.
The king stopped crying and began screaming in pain. That was more like it! Suffer, you miserable old pig!
The room was completely scorched by the time Rukelion was finished. He had enough presence of mind not to melt the stone so the room wouldn't collapse in on him but everything was completely black except the small patch of ground he stood on.
The room was smoking and he felt like he couldn't breathe. He opened the bunker door and let a cool rush of air reach his lungs before staggering out into the hall.
It was done. The entire royal family of Mirea was dead and he didn't feel nearly as pleased as he had imagined he would. He didn't have the same sense of euphoria as when he had killed the water mages or the crown prince.
