''It seems there is enough of you'', he commented as he stood up. He scanned through the class. ''Good day to you all and welcome to our first, actual, DADA lesson. I do hope we shall have less problems than last time. Also, those of you who haven't written their tasks got a 'T' in homework, just so you should know'', he added.
''Now, today's lesson will be about a potentially very dangerous dark spell. The spell itself won't do much harm, but if you use it right, it can be fatal. Now, the spell is called Sectumsempra and it was invented Severus Snape, a former professor in this school and former Headmaster, one of the greatest wizards of all time. Now, to start... can anyone tell me how the spell is used, how it manifests and what effects can it cause, or create, whichever suits you. After we have covered the theoretical part, we shall get to demonstration and practicing'', he said.
