Grey Wind had told him many things. Things which Robb found fantastical. These were stories for Bran, they reminded him in an abstract way of the stories that Bran would drag out of Old Nan. Only Grey Wind didn't have her terrifying manner or way with the stories. Old Nan was a master of words but her stories were more about the rapid horror she could build while she blended the threads of stories together.
The direwolf he found much more direct than Old Nan had ever managed to be. Old Nan had told him about the Wargs that existed long ago. Probably during the age of the First Men but Robb couldn't remember, he'd never been taken by those stories. Her stories were about men trapped in the bodies of creatures and forgetting who they were, even though really they never did.
Grey Wind didn't speak of those horrors. Never even used the word warg. Grey Wind focused on the how if he wanted to he could shift his mind from his own body into the direwolf. Robb wanted to think the idea as fantastic as the stories, but then everyone had gotten a companion. A companion that from what he gathered based on everyone's experience shared a special connection with them.
That's why he had finally decided to try. The direwolf hadn't been able to provide him with clear instructions. Relaxation, concentration, he was to picture a wheel, or even better one of the revolving doors in the hotels. He could push on the door and eventually, there would be an opening that would take him into the body of the direwolf.
He had not been prepared for the exhilarating rush of senses or for the way that beneath his own mind there was still Grey Wind's own quiet and and pleased consciousness just below his awareness. He had bolted off the Millennium Falcon without meaning to really, the direwolf just moved so quickly. He was trying to make sense of the sensations when there was a sound distant, confused he perked the ears of the direwolf and listened more intently. Probably someone afraid of him, he should have been more careful about that.
