Finally, the Silver Mirror shifts, reassembles, and takes on a new form - as a shield with a perfectly reflective surface. It reflects light as easily as it had in its original form, though now it's much smaller and more appropriate for wielding.

The Ringmaster roars again, the shield floating a few inches from her palm. She directs it at the ceiling of the room, straight upward - and unleashes a blast of dazzling light and darkness that seems to consume a pillar of matter in a straight line above her. All at once, the dirt and stone and anything else getting in the way turns into shadow and vanishes, cleaving a tunnel that leads straight out the top of the cathedral.

She spreads her wings and rockets upward, bringing the Silver Mirror with her.
