A tribal guardian based design. I imagine that he/she is some sort of God or angel character.
The gemstones on his/her sides represent the elements -
purple = death
red = life
orange = fire
blue = water
yellow = sky
green = earth
If the gemstones stop glowing, it is because there is a lack of balance in that element.
I imagine that he/she is an all silver (maybe even metallic) wolf. The tribal markings are paint (or tattoos).
