Moonpool

A small pool at the bottom of a stone hollow a certain distance from the clan territories. On one side, there is a steep cliff with water flowing out from a cleft, feeding the pool. There is an underground stream leading out of the pool, which flows into the lake and marks the border between ThunderClan and WindClan. A narrow path dimpled with ancient pawprints leads down to a flat stone "beach" next to the pool.
