A unique publication that attempts to bring together disparate information about the so-called "supernatural beings." Brownies and brownies, elves and dwarfs, basilisks, dragons, unicorns and other magical creatures will appear before the reader as living. The hills in which the Cids live will open, the world ocean will unfold, showing the eyes of Leviathan and Kra-ken, the earthly bowels will open up and from there the zvergs will come out and the gnomes will find out where the legendary islands of Avalon and Buyan are located, like Sinbad the sailor, will rise into the sky on the back of the bird Rukh, will visit the caves, where kobolds knock with their hammers. The encyclopedia of supernatural beings is compiled on the basis of materials on the German-Scandinavian, Celtic, Hindu, Vedic, Slavic, Japanese, Chinese, Arabic and other mythological systems. The Encyclopedia includes besti-arias - a description of fantastic animals, fish and birds, such as Pegasus and Hippopotamus, Garuda and Gamayun.
