Elara lived in a world woven from visible threads, or so she thought.
Every path, every boundary, every distinct thought seemed to have its own clear demarcation.
Yet, there were whispers, faint echoes of something more, something unseen.
Her grandmother, a woman of ancient wisdom and twinkling eyes,
often spoke of the "invisible lines."
"They are everywhere, child," she'd say, "guiding the wind,
shaping the rivers,
and even directing the flow of our very dreams."
