Avacyn

Avacyn is an archangel and the symbol of most humans on the plane of Innistrad. She was the one who fought back the monsters of the night and protected humanity. Here power is slowly waning and people are starting to take notice. Some say she has deserted them, while others don't believe that. In a fight with the demon Griselbrand, both angel and demon got trapped in the moonsilver prison, used for holding demons, named the Helvault.
