In Thai beliefs, Nāgas are considered the patronage of water. Nāgas are believed to live in either water bodies or in caves. According to a popular legend, the Mekong River in northeastern Thailand and Laos was said to be created by two nāga kings slithering through the area, thus creating the Mekong and the nearby Nan River. The Mekong is synonymous with the unexplained fireballs phenomenon which has long been believed to be created by the nāgas that dwell in the river. Thai folklore holds the Naga to be semi-divine, demi-creatures, which possess supernatural powers as has been described in Buddhist and Hindu cosmology. The “Kamchanod Forest”  Ban Dung District, Udon Thani province, which is held in high reverence and fear across Thailand, is believed to be the border between the human world and the netherworld, and is frequently depicted in Thai folklore as the site to be the home of the Naga.
