This is Ryfuunjaz a new character I have designed. He is a panther-gryphon deity. I'm not sure what universe he belongs to but maybe I could tie some of my characters into the same setting along with as Drakivos the Light Collector and Kirzak the Chaos-Wulf, two other fantasy OCs of mine.

Here you can see Ryfuunjaz protecting his followers in his realm against some enemy (something I should also design). Hmm, have him be like the god of the duality of restrained strength and fury let loose for his main aspect and the secondary one being the patron god of the gryphons as well as a god for various feline and avian races (again with the duality of felines vs birds in the wild as generally being enemies).

Also any feathers he may shed are considered sacred artifacts. Finding one can be an omen, being given one is a sign that Ryfuunjaz, himself has put his faith in you. Legend says that one blessed to receive such a feather gains strong powers and becomes a cleric or a paladin in his name.
