Artist's description:

Cornered and separated from the rest of the elements, Twilight Sparkle is ambushed by Trixie. Declaring herself Twilight's long time rival, she vows revenge and launches into a deadly shower of bolts.

The blue trickster seems to have the upper hand. Having used her newfound resolve to train her magical prowess from sunup to sundown, Trixie is rather formidable. The addition of a mysterious new amulet, shining a piercing red, seems to fill the magician with an almost tangible hatred.

Bearing the Element of Magic does not mean that the protege of Celestia is out of the fight, and being backed into a corner, Twilight has no choice but to fight back. Can she knock sense into her haughty rival, or will she be forced to deal with her for good?
