Mr Squall turned to the board, ignoring most of the questions for the time being. "These five symbols represent the five different types of ancient glitch magic. The arrow pointing towards the line represents overload magic. The upward arrow with the two smaller lines represents scale magic. These are known as chaotic glitch magics since they are based on trends, and then outcomes are not always predictable and they can be used for many different functions. The Three Xs with a line through represents spy magic, and the two circles with a line through represents Trojan magic. These two types of magic are forms of evasive glitch, still they abuse faults in magical defenses or magical systems. This final type of glitch magic is special, for it is both a type and sub-type. This symbol, " he said pointing at each in turn, before pointing to the final, bottom one, "represents total chaotic magic. Magic where the outcome is unpredictable. This type has no sub-types because in order to be total chaotic, there can be no trends nor intended functions."
He then paused, "I see many of you rolling your eyes, since most if not all you have not use this magic nor plan to. However magic is more than a tool to be used. It is a tool to be understood. Two of these magics, Trojan and Total Chaotic, are banned nearly universally by law, however these are types of magics you can not run from, nor overpower. These types of magic are more so magic theory, and the only way to overcome them is to out-think them. Not only do I like to start with these to see if we have any particular bright stars, but to demonstrate a point, not only do you have to know your magic, or not need to know any about magic if you can not use it, but knowing magics you can not even use can be very helpful for a variety of reasons, one key reason is defense."
