Ever since the Starks picked up a litter of direwolf puppies in the woods, it’s been like an epidemic. Every kid in the North just has to have one. The parents are all like, “It’s a lot of responsibility and you have to pick up giant poop and not let it eat anyone,” but the kids don’t care and the parents cave. So they built a bunch of parks that were supposed to be a playground for direwolves… but as they grew up, the people started to realize that you can’t keep a wild animal caged for too long and now the parks are more of a fortress where humans gather to keep the direwolves out. It’s really pretty funny when you think about it.
