Birid

Birid in Mongolian mythology, is the general name of monsters. Their kingdom, Biridian Orron, lies five hundred miles under our world, and their ruler, Obtorgoin-Sang (elephant of the air), is one of the Assuri, on whom the fifth ray of the six lights of Boddisaddo-Chutuktu, the saviour of mankind, fell. Herli Khan, the ruler of the infernal region, lives there in a palace surrounded by sixteen iron walls, and this lies in the capital city, which is in the centre of the kingdom.
