Pinkie swallowed nervously as cracks formed in the shield, her hooves running over the surface of the rock she held in her hooves to try and keep her mind away from what was about to happen. She glanced at Lyra who was watching the shield with apprehension, but didn't contribute to it as she was no longer part of the Mage Corps. Under her breath she started counting down from ten, but didn't even make it to three before the shield buckled, breaking completely, knocking ponies back with the backlash.
