The first of the two Schools of Matter, Entropy is the opposing force of Creation; for this reason it is often called the School of Negation. Nothing lives without death. Time inevitably brings an end to all things in the material world, and yet in this ending is the seed of a beginning. A river may flood its banks, causing havoc, but bring new life to its floodplain. The fire that burns a forest ushers in new growth. And so it is with entropic magic that we manipulate the forces of erosion, decay, and destruction to create anew.
