A goddess of the earth. She is invoked to alleviate the thunderstorms created by the weather god ta Ped'n.
Yak Manoid, Yak Takel, and Yak Kalcheng are the guardians of the roots of the pillar which supports the heaven. These three grandmothers also make the waters rise from under the earth, causing henweh. It was Kalcheng who made the four boards in the heavens, over which the thunder-stone rolls at ta Ped'n's command. The dung beetle, Taheun, carried her up to heaven because she was very old and could not walk.
