Snow

There is nothing as pure as freshly fallen snow, hence why in some cultures it is a sign of death.  The tribes to the south see it as the frozen tears of the Guardians that weap for a fallen innocent, while the witches of the west see it as a sign that a pure soul has entered the beyond, their radiant goodness falling from the sky.  Blizzards are a little more complicated in the witches’ eyes, as you can imagine; for how can so many innocents die at once to provide such a downpour?

Myself, I believe that the snow belies both death and rebirth.  In a way, it is the world going to sleep to renew itself.
