Pebbleback's are large, extremely lizard-like dragons, easily identified by their heavily armoured back, head and tail. They are extremely tough, effortlessly resisting attacks from people and animals alike. This, along with their firepower, spewing copious amounts of liquid fire (basically lava), makes them extremely dangerous. However, they do have a softer side: their defenses mean they are often shadowed by small animals, in patricular birds, to help avoid their own predators. In return, they eat parasites that lodge themselves in-between the pebblebacks armour plating, which are otherwise impssible to get rid of. This partnership is especially prevelant in winter, since the pebblebacks internal temperature is enough to melt the snow around it and keep its entourage warm and cosy.
I swear my brain has been 90% dragons these past few months, glad I finally got around to talking about one of my own creations again. Not that I dont like drawing fanart, it's just nice drawing something that's all me.
