Neither Gufuu nor Eyeope know where it came from, but Gufuu seemed to have an interesting ability to have some kind of strange affinity for magics related to the mind, especially dreams. She could manipulate dreams in any way she could Imagine. It was an instinctive ability that she loved to use. Whenever she slept, she entered what she called "the dream realm."
Whenever Gufuu used her magic to put someone to sleep with her magic, she had absolute control of that person's subconscious. So once she entered the dream realm she made a beeline for the giants mind. Once she reached it she brought up his memories prior to "fetching" her. One in particular caught her attention.
Dumbledore had just summoned Hagrid to his office. The devices around the office were whirring randomly. Making the room humm invitingly. The Phoenix trilled a cheery tone and illuminated the room with a pleasant glow. The old war hero was sitting in his chair with a knowing smirk and twinkling eyes.
"Thank you for coming Hagrid," the old man said.
" Of course Headmaster Dumbledore," replied Hagrid.
" I would you to go retrieve Helena," the Headmaster ordered Hagrid, " I would like for you to guide her upon the right path. Please guide her away from the dark side."
" Of course headmaster!" The groundskeeper replied with enthusiasm.
Gufuu let the memory ended there. Eyeope's eye was burning at the memory, while Gufuu was more of a Specter than a person in her rage. If there was one thing Gufuu hated more than anything it was someone trying to MANIPULATE others. Eyeope felt the same especially since he watched Ganon did his best to control both Shadow Link and Vaati. The eye sentries may seem to be extensions of Vaati, but they were still their own creatures (all though made purely of his magic).
