"SHUT THE HELL UP YOU TWO!" She screamed. Her head was throbbing and her stomach was in knots. Something was telling her to stop, begging her to stop, it made her limbs heavy and she slowly felt herself loosing her will to fight. 
But the fire in her fueled her. She fought through the fatigue. She bit her lip until it bled so she'd stay focused. She fought on, though everything in her told her to stop. The flames grew until it was licking the walls and causing some books to become singed or consumed by the flames. Her own clothing began to burn away, as it often does when she is consumed by flames.
