mothermouth is a big cave located at the head of Highstones. it's really an old excavation site, and it goes very deep underground. leaders and medicine cats come here to receive dreams from StarClan, or even lives. at the end of the tunnel is a stone, and in the night, through a break at the top of the stone, the moonlight pours down through and the cavern glows. be careful when treading down the corridor, it can be a tight squeeze, and you may get lost among the many different caves.
