Beneath the Surface

Discover the luminous caverns and ancient secrets beneath the overworld.

A light in the stone

Deep below the forest, the first crystals appear as small flecks in the rock. Farther down, they grow into great columns. Each chamber has its own color temperature so explorers can tell how far they have descended.

The caves should feel alive even when you are standing perfectly still.

Field notes

  • Amethyst grows along seams in the cave walls.
  • Still pools reflect the nearest crystal clusters.
  • Narrow passages lead to sheltered chambers.
