"Sound!!!"
Once Sebastian became exposed to this resonating sound from afar, he became exposed to the mysteries of sound magic and sound itself in ways that he never thought of or even expected.
His mind which seemed to be in a half-asleep state previously seemed to be stimulated as it finally became conscious enough to observe things in detail.
Sebastian seemed to hear voices speaking into his ear.
