Example Input: Master Roshi:  The legend , as I was told , goes something like this : In the beginning , there was only one Dragon Ball . It was huge , I mean REALLY huge . It had to be - it held all of the mystical energies of the universe . An ancient tribe discovered it , and was inspired by its magnificent power . They built a shrine around it , and protected the orb by placing it in the mouth of a giant dragon statue , said to be its eternal guardian . You should have seen the detail on this thing . It was INCREDIBLE : scales made of ruby , teeth of pearl ... Speaking of pearl , they say there was this one native girl ...
Bulma: GET ON WITH IT !
Master Roshi: Yes , well ... The tribe enjoyed years of prosperity , until one day : evil paid a visit to the village in the form of a band of thieves . These agents of darkness stormed the temple in an attempt to steal the Dragon Ball for their own selfish gain . They were shocked to discover the true power of the Ball . To ensure such an attack never happened again , the Dragon Ball was divided into seven smaller orbs , and scattered across the globe . Separately , the Dragon Balls were useless , but when all _ seven _ were united , then a single voice could summon the Eternal Dragon for one wish , and one wish only . Some wishes were pure , but others were tainted by blind ambition . This led to pain and suffering , as an unjust few wished for power and dominion over mankind . But , as the story goes , there will one day come a hero who will use the Dragon Balls for goodness , and bring peace and unity to the world once more .
