J’Zhirr encountered a talking dog outside Falkreath. When this one expressed surprise at a dog that talks, he says “Skyrim is now host to giant, flying lizards and two-legged cat-men, and you’re surprised by me? Yes. I just talked. And am continuing to do so.”
Hmm… pretty witty for a dog.
The dog says his name is Barbas and he had a falling out with his master. He asks J’Zhirr to be the mediator and leads the way to his master’s location up in the mountains. Before setting off, Barbas warns J’Zhirr not to trust any offers from his master.
