The Dawn Winery grounds were vast and very atmospheric at night, under a blanket of moonlight. Crystalfies were flying around, in random places, looking magical. The only sounds were those made by wild animals or the rustling of trees and vines.
One late evening, Diluc went outside even though it was quite cold. He couldn't sleep, so he decided to take a walk. A little patrol wouldn't hurt. As always, it was quiet, but there were no crystalfies around. That was suspicious... As he continued walking, he saw them flying in a strange line, in one direction. He followed them, led to nearby lake.
By the shore, stood a short figure, humanlike, glowing. They had wings similiar to those of crystalfies, with a cloud of the tiny creatures around them. Was it a fairy? Slowly, he walked closer, observing.
