Once, there was a boy named Hero in a village.  A wizard came, searching for someone to complete a quest with him. 

Hero met the wizard, and at first said "No," for a quest sounded scary.  But the wizard pressed and offered him words like "adventure," and eventually, Hero relented.  And then Master and Apprentice were off on a quest.

They then came to their first task: retrieve the magical orb.  There was a struggle, and the wizard threw magic, but it was Hero who retrieved the item.  

And at last, they arrived at the castle walls, but the dragon was waiting for them and swooped down and stole the wizard away!
