"Skinchanger is someone who can share the mind of animals, and wargs are those who control dogs and wolves! When they slip into the mind of their beast, they look like your brother. His body might be here now, but Lord Crow's mind is with his dragons or his direwolf now." The red-haired wildling took a swig of his horn, burped, and continued. "The bond between the skinchanger and their beast is deep and they share each other's minds. Direwolves are one of the most dangerous things you can meet in the true North, and those dragons of yours sound just as strong! Both have strong traits for a leader." Tormund finished his explanation and continued devouring food and drink.
