The origin of magic in Lanji Continent is a power called "reverse". Theologians believe that "reverse" originated from the ancient gods and has been slowly spread to this day. Atheists believe that "reverse" is a force that belongs to the four major races today, that is, it itself is one of the elements of the world.
"Reverse" is an ability that is opposite to the "natural" development of all things. It can transform the elements of the world according to the user's wishes, thereby generating "magic".
In the world today, there are very few magicians who can use light and darkness. The most famous dark magicians and light magicians in history are Graynor Wilder and Lucius Stalf, respectively, four hundred years ago.
Since the "Advanced Holy War of Light and Darkness" four hundred years ago, the number of people who can control the power of light and darkness has dropped sharply, and those who are capable cannot reach their original heights. The reason is a mystery.
