Aaa, here is a quick ref for Deven and some qucik info about the species:

Deven's design is symetrical!
The glow part under his eyes are actually a damage caused when he heat up.

--

He is a coal-dog, a species found deep down in caves.
They are very rare and few of them exist.

In the dark they glow/start to burn, it isn't dangerous for them.
6half holes in the back (as seen on the picture) is always obligatory.
Coal-holes of different sizes and shapes can appear on other parts of them (as seen in his face).

Glow can get stuck on other parts of their bodies (as seen on his tail, legs and buttt)

The burning coal don't have to be red, the fire is connected to their souls so any color is accepted.
Coal-dogs without souls have black fire, when a coal-dog burnout, it's called dry-coal.

In the day/bright enviroment they stop glowing and their pupils become very small.
They are as good as blind in daylight.

They can burn in heavy rain, the water will evaporate/steam away.
Are not able to swim, so they are somewhat afraid of larger waterareas like, seas and lakes.

Thei bodies are usually black, ut they can be other colors too.
Black is always in the fur in someway.

They can chose not to burn if they want too.
If it gets too light (around them), the burning shuts off automatically!

Their blood is the same color as the fire/glow.

They get extreamely hot.
They will not burn to death, ever.
