Yak Takel ('Grandmother Takel') is one of the chthonic grandmother goddesses recorded among the northern Semang of the Kedah-Perak border forests. With Yak Kalcheng and Yak Manoid she sits beneath the earth guarding the roots of Batu Herem, the stone pillar that upholds the heavens, and the grandmothers together can make the waters rise from below, the dreaded counterpart of the thunder god's storm sent against breakers of the divine prohibitions. Kirk Endicott's synthesis of Semang religion notes that the thunder god is aided by a female earth deity sometimes pictured as a pair of sisters; Takel is one of the named figures behind that observation.
