Fairy Mimyu:
Nothing would make me happier, unfortunately, the hatchling is responsible for his own transformation. He must find the four fairy trees and gorge himself on their juice. This task is risky, for the trees are protected by the ghosts of tree guardians. You must see that this Fairy Leaf is affixed to the tree when his thirst is sated.
"Please be more specific about what must be done for him to become a strider!"
