There are many legends when it comes to the possible origin of Santa Claus. One of them states that he is the representation of the nordic shaman who used to bring the magic mushrooms to the villagers. The main entrance of the villagers' yurt would most likely be snowed in during this time of the year, so the shaman would come to their home through the fire opening on the roof, their chimney, to bring them their gifts. Even the concept of naughty or nice has it's place in this legend. A "nice" villager would have a good trip while a "naughty" villager would have a bad trip, so the Shaman would "know" if they been naughty or nice.
