I had a vision of this creature about four years ago, (his original sketch was awful -//-" ) and he's gone through one or two design changes

rough details: he's slightly bigger than a draft horse, his bones are made of the same near-metalic material as his claws and tail prongs, and his long eyebrow-like-things... really have no practical uses :XD:

He sentient, but can only speak telepathically, and only to the person he guards

after several years of having him as a guardian, I finally gave him the name "Spreiton" (pronounced "Sprite-on" )

Spreiton belongs to me

-and he's not a griffin :P he's his own species-
