Other than the many gods and goddesses of the Slavs, the ancient Slavs and the Rodnover descendants of today believed in and revered many supernatural beings that existed in nature. These supernatural beings in Slavic religion come in various forms, and the same name of any single being can be spelled or transliterated differently according to language and transliteration system.
As is common in folklore, there is no standard set of characteristics, or names, and spirits or magical creatures are referred to by many names, often identifying their function or the place or environment of their activity. Such descriptive terms include:
The Vila are the Slavic versions of nymphs, who have power over wind, which they delight in causing storms of high winds. They live around hills, mountains, and high mounds. (cf. Leimakids, Limnades, Oceanids, Dryads, Nephele). They can appear as a ghost-like figure with a long billowing cloak wrapped around them.
In Polish mythology, the Wiła (pronounced [ˈviwa]), and in South-Slavic mythology the Vila (Serbian pronunciation: [ʋǐːla]), are believed to be female fairy-like spirits who live in the wilderness and sometimes in the clouds. They were believed to be the spirits of women who had been frivolous in their lifetimes and now floated between here and the afterlife. They usually appear as beautiful maidens, naked or dressed in sparkling beautiful white dresses, green skirts of leaves, and special fabulous blue robes.
It is said that if even one of their hairs is plucked, the Vila will die, or be forced to change back to her true shape. A human may gain the control of a vila by stealing a piece of the vila's skin. Once burned, though, she will disappear.
