From the announcement:
WizKids is pleased to announce the upcoming release Approaching Dawn: The Witching Hour, designed by Ken Shannon for 3 – 6 players. In a world where Witches cast spells and Demons exist in the darkness, will you be able to banish the evil?
In this cooperative new board game, players are members of a coven who are blood bound - what one witch does affects another member of the coven. Work together to use your magic to bind and banish the demons, imps, fey, possessed animals, and warlocks that are entering the world.
Each witch starts with different abilities and their own spell deck, but not all spells are cast the same. Each card can be played as Black Magic or White Magic. Black Magic is powerful and can help you but will corrupt the other members of your coven. White Magic can be used to heal your own corruption or assist your allies.
