A book at the library reads:
"In the distant past, when the spheros, rabbibunnies, Quetches and grobos emerged from the original primordial soup, centuries before Dr. FunFrock's coup, a prophecy was pronounced. Its text is hardly remembered today and that is why people now refer to it as the "Legend". It explained how "the Heir," when his time had come, would be called to overthrow a tyrant! The secret of the Legend can still be learned somewhere in the White Leaf Desert."
The Book of Bù tells the prophecy:
"The day will come when someone from the present or future species will rise up and say, 'This world is mine from now on, and the key to all powers belongs to me!' This day will surely come because avarice and violence harbor in the hearts of all species of the universe. If the peril on this day is too great, the Chosen One will come forth. He will rise up against the tyrant and overthrow him. He will free and reunite the people, because throughout the years, the Chosen One's ancestors will have prepared him for his victory. They will have left information and weapons in his dwelling. The Chosen One, also known as the Heir, will, however, have to gather together four magical symbols if he hopes to be victorious: the Tunic, the Book of Bù, Sendell's Medallion and a Flask of Clear Water. On the day of peril Sendell will visit the Heir in his sleep and announce the coming of the final combat. The Heir will then have to go to the Well of Sendell where the goddess will endow her powers on him!"
