Beyond Leap'n meadows in fogclan is a large cave that goes underground much like mothermouth in the books. Medicine cats and leaders go down into the cave, as you go there are many crystals in the cave, giving it the part of the name, "Crystal". Inside a small waterfall flows, into a pool, it is much like mothermouth combined with the moonpool you could say, and the pool is called the moonpool, but the whole place is Star Crystal Cave.
