At breakfast the next morning Harry told Ron and Hermione about his late night adventure he had last night.
''Harry why did you not wake me, Harry,'' said Ron.
''How could you have been so reckless Harry,'' said Hermione. ''That could have been a dark wizard.''
''Yea, that thought did occur to me when I was back in my bed,'' said Harry.
Later they had Care Of Magical Creatures it was an eventful class. Malfoy could not do as he was told and not approach the Hippogriff. But he did it anyway and the Hippogriff attacked him. Harry never got a chance to ask Hagrid did he see anything strange the night before. Harry was looking forward to having his first DADA lesson, he would have it in a few short hours. At 12:30 am they left The Great Hall, as they wanted to get to their DADA lesson early. But when they got there, they discovered that many other people had the same idea. As it turned out, there was no need to come so early as Lupin was slightly late. Once he came. They all went in and sat down.
''Hello everyone,'' said Lupin. ''Now you have had two DADA teachers before me. As a result, you are behind. Now I would like to start off by asking you several questions. To gauge your Knowledge. And so I can plan my lessons accordingly. Now, who can tell me the best way to take care of a minor monster such as a Red Hat.''
Hermonie put up her hand. ''The best way to deal with a Red Hat is to stun them.''
''A, yes very good Hermonie. Hermione is there another way.''
''You could always use a Power Symbol, to drain them of there magical ability. Or you could summon a Skeleton Warrior.''
''And tell me, class, have any of you ever summoned a Skeleton Warrior.''
''We have summoned some monsters, but never a skeleton warrior. We have been told they are too dangerous,'' said Hermione.
''No, they are not dangerous. Provided you can control it.''
''I thought they were difficult to control,'' said Ron.
''No they are one of the easiest monsters to control,'' said Lupin. ''Can anyone tell me how do you summon the best Skeleton Warriors.
Lupin looked around the room. After a moment, Ron raised his hand into the air. Lupin nodded to him.
''If you were to use dark magic.''
''Yes Ron you are correct. Now, class, I am going to teach you how to summon a Skeleton Warrior. As a precaution, I am going to create a Power Symbol that will drain the monsters power if activated. Now find a space on the floor. And draw on the required symbol. I will put it up on the projector.'' He turned it on. ''Don't turn it on till I tell you. I need to make sure you have done it correctly. We don't want any of you summoning in something worse than a skeleton.''
Each one of them drew it on. Nevile required some help from Lupin, but he eventually got there. He then took a look at any everyone's symbol. When he was satisfied with everyone's symbol, he told each one of them to turn on the symbol. They did this by taping each of the symbols Points of Power. There were four on this particular symbol. When each student turned on the symbol out rose a skeleton. The skeleton locked just like a skeleton, wearing amour. It also carried a sword. He instructed each student to tell the skeleton to jump. Everyone managed to do this without a problem, except Nevile. Lupin had to give him some help. But he eventually got there.
After class, They went for dinner in The Great hall. They did their homework for the rest of the night, as they already had quite a bit of homework. Harry went to bed quite early, and he woke up a few hours later, around 1 am, he looked out the window. And the hooded figure was in the same place as last night. But the person was only getting started on creating The Power Symbol. The person was very skilled at creating The Power Symbols. The person was a lot more skilled than Harry. Harry watched the figure for ages, the person had quite a graceful way of moving. It was nearly like the person was dancing as they laid the lines of The Power Symbol. The way the hooded figure moved reminded Harry of someone, but he could not think of who. Finally, the person must have been done creating the power symbol, as they then began to turn The Symbol on. There must have been over 30 points of power on the symbol. It took ages, eventually, they were all activated, they then went and stood in the middle of the symbol, as they did yesterday. The hooded figure began by chanting, raising and lowering their hand, with there wand in their hand the symbol kept getting brighter and brighter. After a while, the symbol began to grow outwards. When the hooded figure was done, the symbol was several times bigger than when they started. Harry was unsure what exactly the hooded figure was doing. He assumed they were trying to fix The Grid. He also wondered if the hooded person was a student. He assumed that the person was extremely powerful. He worried that there could possibly be another mega powerful witch or wizard at the school, could he possibly be a dark wizard. After a while, the hooded figure walked back towards the castle. He did think about going to see if he could find out who the hooded figure was, but he decided against it. Just before he went back to bed he realized that he was not the only one watching the hooded figure work, there was a large black dog siting just inside The Forbidden Forest. This was the same dog that he had scene just before The Night Bus had appeared. He soon went to bed.

Note: Sorry I had to use this chapter to explain some of the magic of this AU. I have never liked how limeted the combat was on the cannon HP uneverse. So had to add to it for this fanfiction.
