From Flying Frog Productions:

35 Blank cards. Design your own cards for the game.

These are blank cards that allow you to customize your game.  Printed on the same cardstock with the same coating as the standard game cards, these are blank on the card front and you can write in your own new designs for Artifacts and Encounters for the Forbidden Fortress.

Blank Cards - Mine Set (10 Gear, 10 Mine Artifacts, 10 Mine Encounters, 5 Darkness)

You need a core game of Shadows of Brimstone to play with this expansion.
