What happened was some members of House Stark were venturing out past the North Wall when they came across some elves. The elves were trying to sell one of Santa Claus’ old sleighs because he was looking to upgrade to a new model and needed a down payment. As it turned out, the Starks had just come across some direwolf puppies that could pull it and ended up with a great deal on some economical transportation for the long winter ahead.
Anyway, now it’s a running joke around Winterfell whenever the sleigh comes through. The people yell, “Ho, Ho, Ho!” and rub their bellies. Fortunately, Lord Stark has a good sense of humor and plays along. At least once a winter he’ll ham it up and put red noses on the direwolves, dress up like Starka Claus, and hand out presents. It’s surprisingly good for morale and the economy.
“Winter Is Coming” shows a festive holiday sleigh pulled by two tiny direwolves. It’s a magical time of year in Westeros.
