Harry Potter and the Priestess of the Past.

Chapter one: Back home at Hogwarts.

-In the Hogwarts Express-

"Harry!!! Harry, over here!!" Ron Weasley shouted at Harry. Harry turned around and smiled warily as he saw his friends. "Harry, we've been looking for you at the station, why weren't you there??" Hermione asked concerned as always. "I was already on the train, why? Is something wrong?" Harry asked. Hermione and Ron shook their heads as they sat down in their by now traditional compartment. "So why haven't you written us?" Ron stated while running a frustrated hand through his red hair. "I.. there wasn't much to write about, was there? And besides, I kept in touch with the order, just like they wanted me to..." Harry shrugged. "Still, Harry! Something could have happened to you, or have you already forgotten last year when those Dementors showed up??" Hermione's voice shimmered as if she was on the brink of a panic-attack. Harry tried to calm her down. "Ofcourse I haven't forgotten about that, 'Mione, it's just... I didn't know what to tell you guys without having you hop on to the first train to Little Whinging to protect me..." "So something has happened to you??" Hermione snapped. "No, nothing happened, Hermione, it was just another boring, uneventful summer like always..." Harry thought it best to remain silent about the fact that he had spent his entire summer being deeply depressed about Sirius' death, because he didn't want to worry his friends any more than they did already. "So how's your summers been?" He asked to avert the subject. It worked, Ron and Hermione started to tell him all kind of exciting stories. Harry sat back and relaxed for the first time since the fight in the Department of Mysteries. Even before he knew it, the train came rolling in on Hogsmeade Station, and a steady flow of students emerged from the train and onto the platform, where Hagrid lead the first-year students to the boats and the other students went to the carriages that were pulled by Thestrals. Even though Ron still did not believe Harry, he remained silent of it. The ride to the immense castle seemed to last shorter than usual, and soon enough Harry was sitting at the Gryffindor Table with his friends, looking over the Teacher's table and half-listening to the Sorting Ceremony. Then suddenly Harry gave Ron a nudge and nodded towards the Teacher's table where a beautiful young woman sat on the Defense Against the Dark Arts teacher's chair. "Who is that?" he asked. Ron took up his shoulders. "How am I supposed to know that? Dumbledore will introduce her later on, I'm sure... But check out Hagrid, he looks rather shocked, doesn't he?" Harry needed to cast only one look at Hagrid to notice that Ron was right. Hagrid did look rather shocked and he kept glancing in her direction, only to smile a little when she looked back and than concentrating on the table again. At long last, the Sorting Ceremony was over and Dumbledore stood up. "I have a few announcements to make before the feast begins! As the older students will certainly know by now, the Forbidden Forest is strictly out of bounds to all students, hence the name "Forbidden" forest. Also, a list of not-accepted items can be found on the door of mr. Filch's office, for anyone who cares." Harry was certain he saw Dumbledore wink at the Gryffindor table and he smiled a half smile. "And now, as you have already noticed I'm sure, we have a new Defense-teacher, professor Slatyn!" The Great Hall burst into applause as professor Slatyn stood up and smiled at the students before sitting down again. "That was all for tonight, now all left to say is: eat well..." Dumbledore sat down again and the food appeared on the tables.

After a wonderful dinner, during which Harry had kept a constant close eye on both Professor Slatyn and Hagrid, they went up to the Gryffindor Commonroom where Ron and Harry went straight to the bedroom to get a good night sleep. In other words, they were going to spend the rest of the night talking about the new DADA teacher and Hagrid's rather odd reaction to her. "What do you think it could be, Harry? He looked like he knew her..." Ron said. "A little too well, if you ask me," Harry agreed. "Yeah... weird... did you notice that Snape wasn't even looking jealous?" Harry nodded. "That was the weirdest part of it..." he admitted. "Well, anyway, I'm going to sleep some, if that is possible..." Harry rolled onto his back and closed his eyes. "Goodnight, Ron..." "Goodnight, Harry..." Soon, the boys drifted off to sleep and silence took over Hogwarts Castle in peace.
