Renlekar is the name of a book written by Craig Anderson. It is set in the middle of the second age in arctic Vinterstad. Rudolf, a reindeer, is born with a gift from Odin. It is a gift of great strength, but the gift bears the curse of flightlessness. He leaves home in search of flight training, and along the way he befriends a wayward elf and a misguided shaman. The trio traverse the tundra, discover their destinies, and uncover an elven revolutionary ploy to destroy of the universe. But that is another story.

This is the journal of Klaus, a shaman who survives Ragnarök and begins to build Vinterstad. He and his actions connect the realm of gods and giants to the dawn of mankind.
