Mantle

Origin: In the Crystalspine Reaches a small group of competitive and ambitious young dragons, newly exalted into the Arcanist's service, went a little overboard with coming up with a new potion created from rare herbs and may have... melted a bit of stone. Just a bit of the side of a mountain... A small portion, really. The stone had been melted into a smooth liquid of pure rosy pink that hummed with the natural magics of the land. That small group was still arguing with each other over whose fault the accident was when the puddle moved and coalesced into a small handful of what appeared to be Fae Dragons.

Goo dragons are quiet and curious, each an individual though they seem to share a sort of shared consciousness - aware of each other over great distances and able to silently communicate. No Goo dragon is a stranger to the others. Highly adaptable, they create colonies - building their lairs out of what appears to be a combination of tree sap and their own bodies which is left to harden. These structures are not living, but The Goo still considers their homes part of themselves and mourn any damage they receive. They eat, drink, sleep, and mate like any other dragon, however periodically they must let their forms rest by melting completely into a liquid. This is also how they guard their nests. Hatchlings raised in Goo colonies are considered children of the colony, and bloodlines are bit of an odd concept to them. They are Goo, after all. 

Appearance: The Goo can take the form of any modern dragon species, and are apparently completely liquid except for bone or scale like structures that seem to help them hold their form. Pure Goo is a rosy pink, while extended generations or distant homelands can introduce contaminates to that color. The original generations of Goo is fairly consistent in color and appearance, but more variations are appearing as The Goo spreads outside of Arcane's Territory.

Apparel: Goo dragons are clever, and delight in crafting decorations for themselves out of whatever natural material they can find. Feathers, bones, flowers, etc. They have a strong preference for decoration that matches their coloration. They also appreciate apparel that assists them in holding their form together.
