It destroyed everything on its way until it met a wizard who was able to face it and destroy it. Their battle was said to be legendary and everything around them was obliterated to the ground, their power was unbelievable. This wizard is said to have gained tremendous power from their battle as well as immortality and he is bound to be forever young. Now, he is joining wizard schools in attempts to help good strong wizards develop to defend the world from any future thread. That wizard is me and in all these years I have attained so much power that unleashing a mere part of it would completely destroy the world.
