The Moonpool is the only place where the Medicine Cats and Leaders come to share tongues with StarClan when its needed. Also, it is the only place where Medicine Cat Apprentices may become full Medicine Cats and get their name. It is located along the WindClan and ThunderClan border but RiverClan and ShadowClan cats must travel alongside the lake and stay along the borderline if they decide to visit StarClan's new home.
