Nerezza was angered that she could not find anyone to duel with her. She figured that they were all simply terrified of her. She found that fact simply amusing, but would try and focus on something else so as not to get her arrogance to fill her up entirely. She knew that if she became too conceited, she would probably get killed. Although she was already injured, she would be able to get through this battle without dying. She knew how to take pain, for she enjoyed it immensely. The agony that rippled through her body after each step she took made her simply smile.
The blood continued to drip down her paled skin, staining it dark red. She had no worry of scars for she could simply make them disappear with a simple thought. She had a mind to think that when she died and no longer had control of her appearance, she would be a most horrible sight, a woman of once unrivaled beauty whose various battles had ruined her perfection. Smirking at such a thought, she walked out of the Drawing Room and heard a shuffling in a nearby bedroom. With a giggle, she kicked the door open, smiling over at Thaor absent-mindedly. She knew that he was on her side so she need not worry about him threatening her.
Walking to stand beside him, she turned to face Miseria, her crimson eyes glistening with hatred and excitement. She cast a protective spell around her and then slashed her wand violently in the air, throwing a Cruciatus Curse in the young girl's direction. With a cruel smile, she whispered, "A mere child, Thaor, believing herself to be skilled enough to beat you. Tell me, child, what will happen once you face me? Surely you know that you will die."
Before another spell could be cast, a man burst into the room. Immediately, Nerezza magically locked the door, a red X appearing upon the mahogany entrance. She smiled cruelly and then faced the man again. Her crimson eyes suddenly squinted. She knew him from the Auror Department. He had no idea who she really was and she found that entirely beautiful. Smiling, she whispered, "Tell me, Lupin. Do you wish to die as well? I would be happy to oblige."
