Knyaz Igor and his retinue swear before the idol of Perun, laying down their weapons. Illustration by artist V.P. Vereshchagin from the album "History of the Russian State in images of its rulers with a brief explanatory text", 1896.
In addition to Perun's control over the thunderstorm because of his association with rain, he was responsible for crops by bringing rain to the fields, and so Perun was thought of as the god of fertility. Manipulation of the thunderstorm gave the deity a "thunderous character", which served to second-guess him as a god of war, as reflected in the oaths of arms in his name and his depiction as the patron of warriors, knyazs power and the Rurikovich dynasty.
