The thought of killing this mad man burned in my head. 
 `` He must pay, his life is mine.'' I whispered to myself, though walking through these empty halls is making it seem like I'm shouting. 
 `` It would be rather bothersome if he heard me coming.'' I thought. 
 
 I quickened my pace as I drew my sword; The sound of Dothen being unsheathed always put a smile upon my face. The arching doorway at the end of this long hallway were growing larger as I hastily made my way toward it. 
 
 `` YOU ARE MINE,'' I roared when I was a few feet away from the doorway. A large, brightly light room was on the other side of the doorway; The walls were covered with old, wooden shelves of books; Drapes of earthy colours filled the empty spaces on the walls. 
 
 `` I have come to end your reign you dreaded creature.'' Said the so called, `` Warrior.'' He was nowhere to be seen. 
 `` You can try,'' I replied, `` I will let you have a first strike, since I can not find you. coward!'' 
 
 Suddenly, the hulking man jumped from behind the staircase to my left. He came from behind me, I managed to parry his attempted stab from his glimmering longsword. He turned and rushed at me again. I jumped to the side and stuck my foot out to trip him, stupid fool did not notice this and he fell flat on his face. I pounced on him to prevent escape, and held my dagger close to his thick throat. He struggled for a while, but it was entirely useless. 
 
 `` You know you people can not win...'' He interrupted me with a spit to the face, `` You keep trying and trying, and you never win: never learn. So,'' I reached into my left breast pocket and pulled out a tiny vile of a dark, purple liquid. 
 
 `` This will be VERY painful.'' I said as I put a tiny cut onto his throat, and poured the liquid onto the wound. I stood up and took a few steps back to watch. He jumped to his feet with a furious look plastered on his face. He ran at me, but only took a few steps before collapsing to the ground. He began to violently twitch, he was like a man gone mad. Foam began to spew from his hard, clenched mouth; Teeth were cracking and blood began to flow. 
 
 I walked up to him, and kneeled down beside his flailing body. I grabbed him and held him steady, though it took a lot of strength. 
 `` I will personally crucify each, and every one of your people. Starting with... what's her name, Amealia.'' I laughed as I said this, and watched him scream a final scream, his eyes grew wide and stared directly into mine before they closed with the release of his spirit. 
 
 I stood up and walked away with a smile of satisfaction.
