Deep beneath the surface, the party squeezes through a narrow passage and finds themselves in a large cavern, fully lit by glowing crystals. These gems could be magical--and they're certainly valuable!--but anything precious is sure to have danger lurking nearby...

This bundle combines some simple caverns core sets with the core crystal pieces to enable all sorts of otherworldly chambers. Use the included remotes to make the crystals glow whatever color you'd like, and perhaps see what happens if they have peculiar affects on your adventurers...

This bundle includes a bonus $40 Dwarven Forge gift card.
