Indra is, with Varuna and Mitra, one of the Ādityas, the chief gods of the Rigveda (besides Agni and the Ashvins). He delights in drinking Soma, and the central Vedic myth is his heroic defeat of Vṛtrá, liberating the rivers, or alternatively, his smashing of the Vala, a stone enclosure where the Panis had imprisoned the cows, and Ushas (dawn). He is the god of war, smashing the stone fortresses of the Dasyu, and invoked by combatants on both sides in the Battle of the Ten Kings.
