Description

The soft hum of hidden strings and faint light blooming in the deep night, where sharpness and calm intertwine, transforming into a silent melody. Thread by thread, it captures everything held dear within.

"This? It's just a device for storing instrument strings."
—Evelyn, gently strumming the strings. A low hum fills the air, and as the final note echoes, the enemy falls silent.
