Notice: Arianna's name is pronounced 'R ee ahh na'
19 year old Professor Arianna Black woke to banging on her door. She hurried to the door and opened it. A distressed Hermione Granger was standing there. "Arianna! Help! It's Harry!" she panicked. "Let's go." Ari grabbed a scrunchie and ran after Hermione. They reached Harry's dormitory and pushed open the door. Arianna rushed to his side in an instant. "What's wrong with him?!" asked Neville, scared. "He's having a Voldemort nightmare." replied Arianna. "Ron, get me a flannel and Hermione, get a bowl of cold water." "What's a flannel?" said Ron. "A small towel!" shouted Seamus, Dean and Neville. The two rushed off and returned with the required items. Ari dabbed the flannel in the water and placed it on Harry's forehead. He slowly stopped moving and his eyes fluttered open. "Ari!" he whispered. "Yes?" "I'm scared." Harry latched onto her arm tightly, tears leaking out of his eyes. "It's okay Harry. I'm here and I always will be." she promised, hugging him.
Harry fell to his knees in front of Arianna's dead body, crying. "YOU PROMISED! YOU SAID YOU WOULD ALWAYS BE HERE!" he screamed at the sky. "You promised." he sobbed. He slowly got to his feet and looked at Voldemort. It was his fault. Anger overtook Harry and he Petrified Voldemort then blasted him to smithereens. "I love you Ari." he sniffled. "Harry, she'll always be there for you. Even if she isn't here." A silvery Arianna floated out of her body. "Hermione is right again. I will never truly leave you. I love you little brother." she smiled and floated up, up and up to the sky. An extra star appeared in the deep night sky and Harry always looked upon that star, remembering his honorary sister, Arianna Lily Black.
