Asis (Asista) is the supreme Kalenjin/Nandi deity, identified with the sun: a distant, omnipotent sky-and-sun high god and giver of all good things, prayed to at dawn and dusk. Authored as a deity with era 'primordial' (the cosmic, timeless high god). SOLITARY: the sources attest no individually named divine parent, spouse or child for Asis; the surrounding beings (the oiik ancestral spirits as a class; Ilat/Ilet) are not given as his blood-kin, so no kin edge is asserted rather than inventing one.
