The Void is the space between worlds. When you pass through a Gate, you pass through the Void.
This set includes three of eachof the Void Hound and Void Sorceror Enemy types and the Threat and Spell cards to go with them.
The Void Hounds slip in and out of reality as they move, passing through other models and savagely surprise attacking different targets each turn. This means that no one is safe from the hounds, even those hiding out in the back or around corners!
The Void Sorcerers cast random spells each round, drawnfrom a deck of spell cards. You draw a different spell for each Sorcerer each turn. Each card has two different effects listed, depending on whether it’s a normal casting, or was empowered by previous spells.
As the Flying Frog image used here shows, it is labelled a Deluxe Enemy Set; however, the 2015 GenCon Preview was released as a Deluxe Enemy Pack.
