Perun is the father of true warriors and master of the sky. There is a legend that he once lives among the people of Narr, but he returned to the sky because of the people's acts of sinfulness and lack of faith. Because of this, he directed his rage towards the people and they eventually turned around to try and appease the god.
They got Perun's forgiveness and erected a statue in his visage. For those he favors, he grants them deftness and dexterity.
