Lukomorie (Lukomorie, Lucomoria, Lurkmore) is a fictional land in Russian folklore and history. The Russian word itself is an obsolete term for "bight" or "bay". In the word "luk-o-mor-ie", "-o-" is an infix to connect two roots, "-ie" is an affix (in this case, of relative location), "luk-" is the root for "bend", "mor-" is the root for "sea"
According to classical slavic mythology, Lukomorye - reserved area on the outskirts of the universe, where there is the World Tree - the axis of the world, which you can get to other worlds, because it rests on top of heaven, but the roots of hell. In this world the tree down and lifted the gods. In this sense Lukomorye mentioned in the folk charms and prayers.
Sometimes Lukomorye called the ancient northern kingdom, where people fall into winter sleep to wake up to the return of the spring sun.
