Sorcerer's apprentice.
A long time ago in a distant place lived a boy who had gifts for sorcery, because of his beliefs and upbringing he did not accept this destiny.
But his powers were natural and very impressive, towards things that other sorcerers wanted and could not, his power was so great.
One day his people fell into a curse of darkness so great and severe, the inhabitants and their family encouraged him to help them, his people and his people needed him.
Several sorcerers and knights of the city met, and went to the castle of the dark sorcerer.
They were many days on the road but at last they arrived...
The castle was horrible, dark, gloomy, the sun never came, there was fog and the evil felt.
The boy was very scared, but the other sorcerers told him what to do, explained that his powers came from his grandfather who was the great wizard of Oz, a sorcerer of white magic willing to help others, always seeking the good of all .
The boy was happy to help and together they tore down the invisible wall that did not allow the light to reach the castle and automatically the curse of the people disappeared and the town was filled with light.
