"With bare feet in the dirt, fulmia, ten times with conviction, will shake the earth to its roots, if you have the strength, Jaga's book had told me, and the Dragon had believed it enough not to let me try it anywhere near the tower. I had felt doubtful, anyway, about conviction: I hadn't believed I had any business shaking the earth to its roots. But now I fell to the ground and dug away the snow and the fallen leaves and rot and moss until I came to the hard-frozen dirt. I pried up a large stone and began to smash at the earth, again and again, breaking up the dirt and breathing on it to make it softer, pounding in the snow that melted around my hands, pounding in the hot tears that dripped from my eyes as I worked. Kasia was above me with her head flung up, her mouth open in its soundless cry like a statue in a church. "Fulmia," I said, my fingers deep in the dirt, crushing the solid clods between my fingers. "Fulmia, fulmia," I chanted over and over, bleeding from broken nails, and I felt the earth hear me, uneasily. Even the earth was tainted here, poisoned, but I spat on the dirt and screamed, "Fulmia," and imagined my magic running into the ground like water, finding cracks and weaknesses, spreading out beneath my hands, beneath my cold wet knees: and the earth shuddered and turned over. A low trembling began where my hands drove into the ground, and it followed me as I started prying at the roots of the tree. The frozen dirt began to break up into small chunks all around them, the tremors going on and on like waves. The branches above me were waving wildly as if in alarm, the whispering of the leaves becoming a muted roaring. I straightened up on my knees. "Let her out!" I screamed at the tree: I beat on its trunk with my muddy fists. "Let her out, or I'll bring you down! Fulmia!" I cried out in rage, and threw myself back down at the ground, and where my fists hit, the ground rose and swelled like a river rising with the rain. Magic was pouring out of me, a torrent: every warning the Dragon had ever given me forgotten and ignored. I would have spent every drop of myself and died there, just to bring that horrible tree down: I couldn't imagine a world where I lived, where I left this behind me, Kasia's life and heart feeding this corrupt monstrous thing. I would rather have died, crushed in my own earthquake, and brought it down with me. I tore at the ground ready to break open a pit to swallow us all."
