Grandmother clutched the ancient pottery shard discovered in Keeladi, her trembling fingers tracing millennia-old grooves. She'd grown up hearing tales of Srirangam's temples, stories passed through generations like invisible threads connecting past to present.

Some legacies transcend technology; they simply need witnesses brave enough to honor them.
