Who is Oracle from Blue Adept and what is their importance?

The Oracle is a mystical entity who is frequently discussed but never actually appears in the novel. She prophesies that Lady Blue is the ideal wife for the first Blue Adept and tells Lady Blue "None by one, One by Two" in regards to bearing children. The Oracle directs Stile to his fate as the Blue Adept and informs Hulk that Stile needs the Platinum Flute to be successful against the Herd Stallion at the Unolympics. She also tells the Red Adept that Blue will destroy Red. The Oracle's prophesies are obscure but always true.
