Pantheons of deities are not unified among practitioners of Slavic Native Faith. Different Rodnover groups often have a preference for a particular deity over others. The Union of Russian Rodnover Communities founded and led by Vadim Kazakov recognises a pantheon of over thirty deities emanated by the supreme Rod; these include attested deities from Slavic pre-Christian and folk traditions, Slavicised Hindu deities (such as Vyshen, i.e. Vishnu, and Intra, i.e. Indra), Iranian deities (such as Simargl and Khors), deities from the Book of Veles (such as Pchelich), and figures from Slavic folk tales such as the wizard Koschei. Rodnovers also believe and worship tutelary deities of specific elements, lands and environments, such as waters, forests and the household. Gods may be subject to functional changes among modern Rodnovers; for instance, the traditional god of livestock and poetry Veles is called upon as the god of literature and communication.
