The note, a single, perfect sphere of sound, hung in the silent cosmos.
The glow, a soft, inquisitive pulse of light, did not answer with a sound of its own, but with a change in its own nature.
It shifted from a gentle luminescence to a focused beam, a silent question aimed directly at the heart of the note.
The note, in turn, did not shatter or fade, but trembled, its perfect roundness vibrating with a newfound complexity.
And in that vibration, Kairos felt the birth of the first echo: the memory of a question and the promise of an answer, a story waiting to be told.
