Equestria has existed for thousands of years, its history carefully preserved through books, monuments, and the memories of its rulers. But what if history forgot someone? Three months before the Summer Sun Celebration, a mysterious "unicorn" emerges from a crack in reality deep within the Everfree Forest. With no home, no family, and only fragments of memories from a forgotten past, he settles in the quiet town of Ponyville, hoping to build a new life. As he slowly befriends the ponies around him, strange memories begin to surface-memories of a life that shouldn't exist, of faces that should know his name, and of a sacrifice that erased him from history itself. Hidden beneath Equestria lies a truth buried for over a thousand years. Some secrets were forgotten. Others were never meant to be remembered. And when the past finally awakens... Equestria may never be the same again.

Y/n is a man with control over time itself.
