The Nāgasoline will be the followers of Virūpākṣa (Pāli: Virūpakkha), one of several 4 Heavenly Kings who guards the western direction. They act as guards on Mount Sumeru, protecting the dēvas of Trāyastriṃśa from attacks through the asuras. In Thailand and Java, the nāga is often a wealthy underworld deity. https://128.199.208.170/
