The Nāgas would be the followers of Virūpākṣa (Pāli: Virūpakkha), one of the Four Heavenly Kings who guards the western path. They work as guards on Mount Sumeru, protecting the dēvas of Trāyastriṃśa from assaults from the asuras. At the center of your Naga Empire’s cultural identification was serpent worship. https://128.199.208.170/
