Nirriti
Dissolution or ruin personified. The Rigveda names her about twelve times, nearly always asking her to go far away (10.59 refrain); the dove and owl are her envoys (10.165). The Atharvaveda speaks of her collar and iron fetters (6.63). The Brahmanas give her the south-west, the colour black, husks, and natural clefts in the ground, and identify her with the earth in its destroying aspect (Shatapatha 5.2.3, 7.2.1). The Mahabharata makes her wife of Adharma and mother of Fear, Great Fear and Death, and also lists a male Nirriti among the Rudras; later tradition has a male guardian of the south-west.
