So, with a checklist in mind, he started working on writing down the 24 basic rune symbols on the mana papers. But his first attempt left him baffled. Every time he started to write those symbols, the splitting headache came back stronger than ever.
He also needed to be absolutely focused while doing it, great willpower was required since his mind simply wanted to let go. Having a focused will power while engraving the rune symbols is what is called Runic direction. He also had to keep in mind to put proper amounts of mana into the rune engraving pen in the process. It was extremely difficult.
Fortunately, Axel did not lack willpower or focus, but what he lacked was harmony. Runic Direction, Energy, and Runic language all three needed to achieve a harmony upon the completion of the engraving. His first try was a profound failure.
