Slavic mythology and Slavic religion evolved over more than 3,000 years. It's conjectured that some parts of it are from neolithic or possibly even mesolithic times. The religion possesses numerous common traits with other Indo-European religions.
Very few written records are known to survive from the centuries before Christianization. The controversial Book of Veles is believed by some to be a sacred text of this religion. Saxo Grammaticus is another source with disputed authenticity. Chronicon Slavorum by Helmold is generally accepted as a genuine source, covering culture and events in the late 1st millennium AD. One unreasonably underestimated and quite enigmatic source is Veda Slovena (http://tribal.abv.bg/veda/titul/parva.htm) - a compilation of archaic Bulgarian ritual songs, that preserved important fragments of Slavic pagan lore.
According to the Book of Veles, Slavic religion recognizes three realms: Yav, Prav, and Nav, Yav being the material world, Nav the immaterial, and Prav being the laws that govern them. The emphasis on the three realms is particularly characteristic for the Slavic neopaganists that draw on the Book of Veles.
Main symbol of ancient Slavic cosmogonic ideas was the World Tree. Slavs imagined that all three realms are vertically situated on an gigantic oak tree, that holds the whole Universe. In its crown was Slavic Heaven/paradise, so called Svarga, residence of Svarog, or Iriy. At the oak's trunk was the world of living creatures, the reality - Yav. In the oak's roots was Hell, residence of Chernobog, Morena, and Zmey.
The original supreme god of Slavs was probably Rod. Information about Rod worship is scarce.
In some branches of Slavic religion, the supreme god is Svarog (senior member of Triglav). But exactly because of his nature he was not the most worshiped: that was Perun, while tribes that were occupied mostly with cattle could pay most attention to Veles and so on.
There is no single well-established pantheon. One attempt at establishing such an "official" pantheon was made by Vladimir I, Prince of Kiev in 980-988 religious reform, immediately preceding the Christianization of Ruthenia. Vladimir erected six or seven idols near his court - Perun as a supreme god, Veles, Hors, Dajbog, Stribog, Simargl, and Mokosh as tribal gods.
It should be noted that many of the gods may be known by different names even in the same language. Calling gods by proper name was considered bad luck, thus gods were called by adjectives, describing their qualities. Over time, those adjectives took life of their own.

Some of these individuals have had real-life prototypes, but most stories (bylinas) about them became pure fiction, involving magic etc.
