From the Publishers website: It is time to delve where no DF adventurers have journeyed – into the dark of the Catacombs Set. This amazing set can be used for a variety of cool adventuring locations from crypts and catacombs – and into the lair of a dark Necromancer. This set works great with our classic Dungeon sets as they have similar coloration, and the pieces are the same size. The pieces come completely hand painted, and they are ready to use right out of the box. There are some "special effects" available in this set. Battery-operated, flickering orange LED lights burn like "flames" in four Corner Wall pieces. The effect is amazing in a darkened room! We have also included eight freestanding walls in this set to allow GMs ultimate control of their set-ups. The pieces included: Catacombs Set: (47 pcs) 4x Corner Wall w/Flame, LED Light (& 3 batteries) 4x Curved Wall w/2 Standing Skeletons 4x Straight Wall w/Skulls in Fireplace 4x Straight Wall w/4 Shelves of Skeletons 2x Straight Wall w/Arch 10x Floor (2” x 2”) 4x Freestanding Long Wall w/Skeleton Shelves 4x Freestanding Short Wall w/Skeleton Shelves 4x Curved Wall 4x Skulls Pillar 1x Bones and Debris Pile 2x Skulls Pile
