According to Brandir's idea, as long as the other Grand Druids agreed, he would tell Katherine the prayer for entering dreams, allowing the Elf Queen to enter the Natural Dreamscape while she slept at night.
The Natural Dreamscape would provide the dreamer with the most comfortable environment, allowing complete relaxation of mind and body, so Katherine could finally get a good night's sleep.
But this request was unequivocally rejected by the other Grand Druids.
They all thought Brandir had gone mad—who chases love by offering the Emerald Dream Forest's greatest secret as a gift? They hadn't even won the Elf Queen's hand, and already the Druids were bleeding a loss.
The situation was somewhat out of control; Brandir had fallen blindly in love.
