Holy shit I made a fan tribe
I never thought I'd be able to do this-
Now, similar fan tribes are probably out there, it wouldn't surprise me. But I'm still proud of these volcanic babes okay?

~VOLCAWINGS~
Description: black/grey/ash and orange scales, forked orange tongues, tails shaped like a shrimp's
Abilities: can spit deadly magma, melt metal with their touch, breathe in a river of lava as well as underwater
Queen: Queen Scoria

So since the Nightwing Guide if the Dragons of Pyrrhia have vague descriptions, here's a less vague description:
So, do you know Peril the Skywing? Of course you do, everyone does.
Well imagine an entire tribe just like her.
Those are Volcawings.
Volcawings live in the Kingdom of Magma. To the south of the kingdom is a huge mountain range full of volcanoes and rivers of lava. To the north is a beach, and just below the depths of the underwater world are also volcanoes. So it's pretty helpful how they can breathe both in lava and underwater, since that's pretty much where they get their food sources.
But since volcanoes don't provide many life forms to devour on, Volcawings don't eat very much, and can go a long time without food. If they're desperate for food, then they'll eat rocks.
The inside of a Volcawing is quite strange. Their blood is magma... Literally that's what it is. Magma.
And even though Volcawings are quite hot and can burn through metal, they can learn to control their heat. They can't completely turn it off, or they'll die, but they can die down their heat to a bearable temperature. When they do this, however, their blood gets warmer; meaning the magma inside them would be hotter than before. So if they spat lava at you, or they bleed, it could possibly be hot enough to melt even the rocks around them.
They're very dangerous dragons, which is why they like the isolate themselves from the other tribes. So if you come across a Volcawing, and they dart away from you, that's honestly perfectly normal. Whether you choose to follow them, though, could be a good decision, or a decision that results in death.

Volcawings are currently a closed species. If you want me to open the species, I probably will, but it has to be multiple people who want them.

Well, that's all ;0
