Who is Dulcie from Going Bovine and what is their importance?

Dulcie is a punk rock angel who has been sent as a guide, of sorts, for Cameron's quest. She has huge feathered wings and curly pink hair. Dulcie is Cameron's guide, friend and eventually his lover. It is because of Dulcie that Cameron comes to understand the meaning and power of love. Dulcie describes herself as a messenger for a higher power, but she never addresses what this higher power is. She assigns Cameron his quest: to find Dr. X and save the universe from the evil dark matter that has created the Wizard of Reckoning.
