The spell burst from her in a rush of violet light, lifting the leaves and twigs and sticks from where they fell and carrying them in an invisible breeze. A few sparked and sizzled in the air, before landing as a thin trail of ash. She made no attack, but her most powerful magic was still a force of flame.
All that light and heat concentrated in the air directly in front of her, forming an image. She saw it clearly, before she recognized exactly what she was looking at. A huge depression in the ground, circling with mechanical, regular layers. A truck bigger than some houses rolled past, as slow as the old crawler that once took the space shuttle to its launchpad.
