This story follows Biography of a Tyrant, but it can also stand alone nicely.

Nightmare Moon is banished, imprisoned in the moon which she once controlled. It is the first great battle that Celestia has ever lost.

But only as the smoke clears does she fully realize what has just transpired.

Now, she also stands upon the precipice.

The choice is hers.

(Chronology note: this tale takes place before the series begins, and before Cadence and Celestia meet.)

(Chronology note: this timeline continues with Cadence of the Crystal Empire.)

Part of the Elsequestria Continuity and the Sunset Rising Continuity.
