Darkness nestled in the heart

Exploration Stage: Tiger's Spring
From: Monk
Description: Pride shattered Huw's heart. Chaos-inducing particles began to appear on the instruments he created as microscopic defects. When Fuu saw this, he was furious, and he and his instruments were increasingly engulfed in chaos. You can see it in the bottle there. I want you to give it to me.
Completed: Do you see the particles of evil energy enveloping that bottle? This is a symbol of the chaos in Fu's soul. His mind has been taken over by resentment, and every instrument he created was tainted by darkness.
