Indra is the most prominent deity in the Rig Veda, with approximately 250 hymns dedicated to him - more than any other god. He is described as the god of rain, thunder, and war, and is famous for slaying the dragon Vritra to release the waters. While Agni (fire god), Varuna (cosmic order), and Marut (wind deities) are important Rig Vedic gods, Indra occupies the central position in the pantheon.
