In Hinduism, the nagas ("snake") are an ancient race of snake-humans that brought fertility to their venerators; they were especially popular in southern India. They are Varuna's servants. Nagas live in a type of palace called Patala[?], many of which are in Bhogavati[?], an underground city. For Malay sailors, nagas are a type of dragon with many heads; in Thailand and Java, the naga is a wealthy underworld deity. They are children of Kasyapa.
