|Moon of Silver|
Innistrad's moon is both a source of hope and a harbinger of woe. Many Innistrad astronomers believe that the moon is a vast desert made of grains of pure silver, and that any extant silver on Innistrad originated from the moon. Cathars and priests know the power of specially blessed silver to harm werewolves and ward off other horrors, so the moon has become associated with the divine strength of the archangel Avacyn. Some even perceive the shape of a heron in the areas of dark and light on Innistrad's moon, and so the heron has come to be a symbol of Avacyn. But the rise of the moon can also dampen protective magic and cause werewolves to transform from human to wolf. The fickle silver moon seems both to serve humanity and to bring out the worst evils within.
