The magic of the cursed king

My name is Aldwin windin and my dream was to be the magic king but sadly I didn't think it would come true May 7 528 I was born into the weakest family of mages in Lavania and was chosen by one of the magic order of the next generation of the magic knights .My father was a low class magic knight of the ability of ash magic and My mother was a dark magic user.I was only 15 when I was invited at the banquet of the magic kingdom of Lavania and my parent were attending and was treated like scum by the noble and after the magic knight selected by the magic order we were instantly teleported to a room were the magic king maid an announcement about the 100 people who were selected today shall be tested today if you are Qualify for the next generation magic knight and only 25 of your shall make it out to be magic knight and the magic knight proceeded to explains the five principles of magic and the magic types which are common which consist of ash,blaze,cotton,

Rubber,and metal, uncommon consist of dark,wood,cement,water,and stone, rare magic has fire ,earth, wind ,glass, portal, the legendary magic has sunshine, hell blaze,barrier,light,magma,but there was the last one which only the 1 and the 23rd magic had which was called sacred binding which had the power of all magic possible and even beyond the limit of the magic world itself.Then this high ranking noble came up to me and said my name is Erin Morningstar don't you forget that ur peasant and I'm am going to be the best magic knight so don't get in my way he said.Then the magic summoned his familiar the lion of pride and the lion had a orb with him to have everyone put there mana into it to see what type they are so Erin went first and he got sunshine and more went until I was the last one and it took longer than I expected and the lion stuttered and said sacred binding in a shaky voice where everyone was shocked out for words,But now it the mana test to see how much mana do u have and your going to have to cast a spell and that the magic will tell u what the words are for spell.The mana told me to assval rekhu and it cast a sunshine based attack call cruel sun
