NAVKA

Nav (Croatian, Czech, Slovak: Nav, Polish: Nawia, Russian: Навь, Serbian: Нав, Slovene: Navje, Ukrainian: Мавка, Mavka or Нявка, Nyavka) is a phrase used to denote the souls of the dead in Slavic mythology. The singular form (Nav or Nawia) is also used as a name for an underworld, over which Veles exercises custody—it is often interpreted as another name for the underground variant of the Vyraj (heaven or paradise).
