What's left of a mare after you take away everything she holds dear?

Starlight Glimmer is about to find out.

After she destroys the scroll containing her fork of Starswirl's time-travel spell, she and Twilight are spirited away into a reality no less bleak than the one Twilight has just shown her. Out of rage and other things, the two mares attack each other.

Things spiral out of control from there.
