Berghexe

Finally one of few named breeds from Temeraire universe from central/east Europe.
I was trying to make it's look somehow correspond with the name "mountain witch". Since many of the breeds from eastern Europe are said to have kinds of natural bone-plate "armours", I thought that Berghexe never fully developed this kind of covering - breeders only managed to get the development begin. This caused the dragon to look like it's covered in warts or little stones - and witches are often portrayed with big, ugly wart somewhere on their faces.
