Crystal Cave

This is a cave made up entirely of crystals and gemstones. This is where a cat will travel to in order to recieve their nine lives and become leaders of the Clan. Also, the medecine cats and the medecine cat aprentices of all four Clans go there to share tongues and speak with StarClan. They are allowed safe passage through the Clans to get to the Crystal Cave. They go every half moon.
There is a small hole in the top of the cave, about a tail-length wide. There is a huge slate of diamond in the center of the cave, and when the moon's light is shining directly through the hole, it will hit the diamond slate. In doing so, the moon's light will bounce off the diamond and rebound off the walls and onto the pure crystal walls, lighting up the cave in a bedazzling array of glowing silver light.
