Harmonic Keys

Gadget

A delicate instrument that can be used in performances.
In the eyes of the ancient philosopher-debaters, the melodies of the mortal world are but a rough imitation of the universe's symphony. However, the King of the Immortals captured the unusual motifs within the musician's performance, then instructed the harmonist to fix the eternal music onto every key, allowing anyone who plays it to join in the grandest of symphonies.
