The Nāfuel tend to be the followers of Virūpākṣa (Pāli: Virūpakkha), among the Four Heavenly Kings who guards the western direction. They act as guards on Mount Sumeru, guarding the dēvas of Trāyastriṃśa from assaults with the asuras. In Thailand and Java, the nāga is often a rich underworld deity. https://128.199.208.170/
