Ok, I have some stuff hammered out about them.

Above view and wingspan.(As you can tell, I'm not skilled in this type of dealy)

Location: mountains, normally nestled into a idle volcano. They primarily live in small packs of families over the territory.

Description: Top scales are fans, flaps under their wings, legs, and at the tip of their tail. Males have streaks behind their eyes while females have teardrops under their eyes. High percentage of them come in grey, black, and white. But may come in other colors, though always a muted shade.

Abilities: Can blend into the surrounding rock and sky. Great flyers. They spit a greenish flame, that's produced by the ash they constantly inhale on the mountain. If a dragon is removed from the mountain, instead of spitting fire, they have only the corrosive smoke the flame produces leak from their jaws.

Queen: The Queen normally sleeps inside, closest to the volcano. The groups on the mountain encircle her home, coming by every year.
Last known Queen was-
Queen Mist

You can use Smokewings if you want, just tag me so I can see.

I tend to wonder this too... Just listen to it.
