Zafiro Azul, son of Zanahn (sort of; it's complicated). He's had six arms since birth, and spent the first thirteen years of his life living on a tiny floating island, completely alone apart from a pair of spirits who served as his tutors and servants. He never encountered another living being until they started allowing him out to other places, and even then, he was little more than an errand boy, slaying monsters and recovering people's treasures for them for little better reason than because he'd been told to. On the day the spirits judged him to be a worthy adult, they vanished completely and opened all of their portals, leaving Zafiro to his own destiny. As he traveled, he started to notice ways that he was different from everyone else; not only could he recover from any injury, even seemingly fatal ones, but he was immune to all forms of transformation (voluntary or involuntary) and mental control. Now he wanders, seeking a purpose to his wanderings and performing heroic deeds great and small wherever he goes because he doesn't know any other way to live.

Zafiro is a gryphon, sort of; he's more like an avian-headed human with short downy feathers all the way down to his stomach. In his wanderings around different worlds, he's become familiar with magic as well as high technology - he can't use magic himself or design machinery, but he's savvy enough not to be scared by much.
