Ukanlos Horned Flute

Embodiment of the white god's 10th power: songs that destroy the world.
Among the weapons born from the "White Snow God," this hunting horn's roar calls to mind the world crumbling at the god's song, and so it is called "the Tenth Song Made Real." It is said that anyone who hears its melody, whatever their kind, walks off somewhere as if in a dream.
