"Good morning students. Welcome to yoyr first class of this year." with that Anna Catherina went into the classroom with waving robes. She strode quickly to her desk, put her books down and then turned around to face the class.

"First of all I want to make clear that Defence against the Dark Arts will be one of your most important classes this year. So I will not remind you again that I expect you to pay always full attention to my lessons. Nevertheless all the other classes are important as well." She looked around and saw Neville Longbottom and Seamus Finnigan mumbling to each other. She put her hands to her temple and started rubbing them while she watched the boys for some seconds. " Well ... well ... well ... Mr. Longbottom, Mr. Finnigan. Though you might not agree, History of Magic is as important as any other class. Never forget what we can learn from history. 5 points from Gryffindor for both of you for not paying attention and for slandering on Professor Binns."

She went back to her desk and took two pieces of parchment out of her bag. "Before we will now start with our first lesson I want to inform you about a project which I'm offering to all of the students this year." She made a little pause, looking around. "It is very important that you are able to defend yourself. Sometimes magic might not work because of many reasons., Due to this I offer a course for self defence. The participation is voluntary. Your abillities will not be graded. You will get a note in your report that you participated the course." She went over to Susan Bones and Hermoine Granger, class representatives of Hufflepuff and Gryffindor, and handed them the parchments. "You please make shure that everybody who wants to attend the course sign in the list and then return it to me till the end of the week." The girls nodded. "Uhm ... Professor ?" She turned around "Yes, Mr. Potter ?" "Will all students be in the same course ?" "I don't know this by now." she replied. "It depends on how many students want to participate. If there are going to be enough I will make one course for every year or maybe one for two years."

She went back to the desk "Any more questions ? ... No ? ... Well then let us start. For the beginning I don't want to pick up the counter curses again. We will start with protection by magic barriers. Please open your books on page 200 and read the chapter about the "Paries ex ... exoriri""

With that she sat down and watched the students open their books. She then picked up a book by herself and started reading.

Fifteen minutes later she stood up again. "I gues You have finished reading by now. We will start with one of the more easier and less dangerous elements, the air. Please step away from your desks and don't forget to pick up your wands. We need some space." With a wave of her wand the desks shuffled to the walls. "Now watch carefully while I show You how to perform the spell." She stepped back raised her wand and said "Paries ex aer exoriri !" With her wand she drew a huge rectangle in the air. A second later a barrier of 2 meters hight and 3 meters length appeared in front of her. It looked quite spectacular. "This spell will protect you if you are trapped in a walk and you want to shut it. It's not usefull for the protection of your body. For those who want to pass through the barrier it's like to walk through a storm. It will not hinder spells, curses or charms to go through it. We will talk about this variation of the spell later. The more powerfull the barrier is the more difficult it is to pass through it. Mr. Banerji, would you please come over here and try to walk through the barrier." The tall Hufflepuff boy went over to where she was standing. He then faced the barrier and moved towards it, first qick but then he was getting slower and slower. When he stood right in front of it the others could see his hair waving in the wind. He brought up all his strenght to walk on but the wind held him back. "Thank you, Mr. Banerji." She waved her wand again "Infinite cantatum !" The barrier disappeared imidiatly.

"Now please distribute yourself in the room. Make sure that there is enough space around you. I will walk around and help if it's neccesary."

The students took their places in the room and started trying to perform the spell. Anna Catherina went around and helped with the pronounciation or the exact wave of the wand.

55 minutes later two shouts of joy made her stop and turn around to where they came from. She could see two barriers of one meter hight and 1 meter lenght in front of Susan Bones and Ron Weasley. "Very well, Ms. Bones, Mr. Weasly. Let's see how strong they are." She went over to them and tried to walk through it. After a minute she successfully passed through the one of Ron and it took her nearly three to pass through Susan's. "Very, very good for the beginning. 5 points to each house. Class will be over in a few minutes. I want all of you to keep on trying with the spell. Please also read the chapters concerning the other five elements. We will continue with them in our next lesson. Dismissed." With a wave of her wand she brought the desks back to their original positions.

The students started to shuffle out of the class room. "Ms. Granger, Mr. Potter ! I need to talk to you for a minute." She gestured them over to her desk. After all of the other students had left she started to speak again "I'm very aware of the difficult situation both of you are in at the moment. Professor Dumbledore told me everything I needed to know. I care for all of my students but at the moment you're the ones who need a little bit more attention." She made a pause and watched both of them carefully. "So please be free to come to me at any time if you have any question or need someone to talk to. I also want you to wear this one." With that she handed both of them an amulett. "It will alarm me imidiatly if you are in any danger. Please wear it all the time." They took it and placed it around the neck. "Thank you." they said. "I also hope you will attend my course. You may go now."

After the teens had left the class room Anna Catherina leaned back in her chair and waited for the next class to arrive. She was quite content with the first lesson.
