Echoed Beat is a simple watchmaker from Canterlot. On a business trip to Ponyville to sell his wares, he would never expect to meet any of the heroic mares known as the Elements of Harmony. In fact, he'd never met any of them in his life, and never had any real plans to.

When he arrives in Ponyville, however, he discovers that the Mane Six appear to already know everything about him. His past, his craft, what he carried in his cart and what he carries on his soul.

Echoed Beat never expected to be friends with the Elements of Harmony.
He certainly didn't expect them to be crying at his funeral.

The Elements of Harmony have a problem.
In the past they'd saved thousands of lives without breaking a sweat.
Why, then, can't they save a single stallion?

And worse, why does the same day keep repeating itself?
Why must they watch him die?
