The Wizard of the Tree was a legend among magic users.
According to myth, many years ago, a powerful Wizard created his own world inside a magical tree in the middle of nowhere. The Wizard of the Tree wanted to be alone and did not allow visitors to come close to his tree.
Before he left the world of men, the Wizard used to be teased and scolded about his looks. Feeling ugly and unwanted, he retreated into the Wizard's Tree and made a beautiful world all for himself.
