Sand dragons are violent, irritable, and cunning creatures, given to raiding farms for cattle, but leaving the farmers alive as a sign of "mercy" (never mind that the dragon has just devoured the farmer's livelihood). Not exactly evil, but definitely not good, sand dragons are motivated only by what is good for their own survival. In fact, they have a difficult time understanding why any living creature would think any other way.
Sand dragons lay their eggs deep within the sand of the desert, which is partly responsible for their name. As the eggs hatch, the hatchling dragons claw their way up to the surface, giving the impression that the dragons spring spontaneously from the sand. Even at that age, sand dragons have fully developed horns and claws, enabling them to burrow just as easily as their parents. Sand dragon wings are actually not wings at all, but thin membranes of a similar consistency and material to regular dragon wings. These membranes stretch between a double row of spikes that run the length of a sand dragon's back, from the base of its skull to the tip of its tail. These spines can collapse flat along a sand dragon's back when it burrows, protecting the fragile membranes from damage. A sand dragon can also lie flat on a sandy surface and flutter its wings to cover itself with sand, much as a stingray flutters its "wings" to conceal itself on the ocean floor.
In fact, sand dragons make their lairs under the sands, and only emerge to hunt or mate. As a result, sand dragons smell of freshly turned dirt and dust - not a particularly unpleasant smell, but a distinctive one. Due to their burrowing ability, sand dragons have little difficulty disguising their lairs; only their nostrils lie exposed (allowing them to breathe). When sand dragons travel underground - their primary means of sneaking up on prey - they simply hold their breath. Sand dragons are most fond of lizards and rodents, though the older they get, the larger the prey. Young adult and adult sand dragons eat goats and jackals, mature adult and older sand dragons go after cattle, camels, crocodiles, and even giant banded lizards.
Sand dragons acquire a good deal of treasure, though they have no real use for it aside from bait for prey. They generally bury it in the sand under their lairs, and lie waiting for the sound of shovels digging toward them.
The Sand Dragon's head is a moss of thick, short horns in irregular rings around its snout, jaws, and neck, giving its entire head a distinct appearance reminiscent of a lamprey. Its large scales are a dark gray-brown, and a crest of broad, short spines runs from its head to the tip of its tail. A membranous frill runs between these spines down the length of the dragon's body, allowing it to undulate through the air rather than flop like other dragons. The dragon smells of dust and dirt.
A sand dragon's breath weapon is an abrasive cone of grit.
