Location: Crystal Caves

The cave appears to be little more than a cleft in the side of the hill.

Once inside, the cavern opens up to a vast, expansive chamber where one could easily
get lost in all of the nooks and crannies. 

The second room of the crystal cavern shows huge points of quartz and amethyst that glow with a surreal
blue / violet light.

The lower cavern has been altered to hold bridges and stairs to permit entry to the heart of the cave complex.

Beyond the the winding stair, beyond the 'forest of crystals' is the Crystal Heart. The large crystal point floats above a shaft of light and shadows resonating with a purple hue.

A shard of the crystal is found by (someone) and the quintessential resonance can be felt within it.

With a bit of Prime, the crystal will resonate and can be used as a 'bread crumb' to help the seeker find the cave.
