Balefire

Balefire is a guard drake that Barkley adopted in Episode 29 after the fight with the Cult of the Dragon pursuers. 
Balefire is poorly trained and only seems to understand Draconic, which Barkley does not speak, so he's not the best behaved pet but we love him anyway he's a pretty good dog. (Not as good as Boris, but that's okay, that's an extremely high standard)
The party left Balefire with Desdemona in Elchezar.
