Blue dragon

Blue dragons, also known as storm dragons, are orderly creatures and are unusual for chromatics in that they keep fairly well-ordered, hierarchical societies. They are more likely to be mocking and manipulative than outrightly cruel or murderous to 'lesser' creatures, aided greatly by their natural talents for hallucination. They are infamous for tricking desert travelers into drinking sand or going miles out of their way to avoid nonexistent dust basins. Their breath weapon is a line of lightning or a large electrical charge.

Physical description
Blue dragons are physically distinguished by the single large horns protruding from their heads and also by their ears, which are rather large and frilled. The tail is thick and bumpy, like that of a caterpillar. The wings are more pronounced than most other species'. They smell like electricity or sand.

Combat
The blue dragon excells at aerial combat, perhaps moreso than any other species of dragon. Their lightning discharges are very easy to aim at other aerial foes, or at creatures below them on the ground. They are also extremely adept at burrowing in sand, and often lie in wait just below the surface of the desert for prey. When they are so burrowed, their large horns can easily be mistaken for pointed desert rocks.

Breath weapon
Blue dragons use a shocking burst of lightning.

Lair
Blue dragons are native to arid wastelands and deserts. They make their lairs in underground caves; easily accessible to the dragons, as they can burrow through the ground. These dragons fly above their territory, using the bleak landscape and its sparse terrain features as their best chance of spotting opponents. The typical blue dragon lair is dug into one of the towering rock formations that dominate desert landscapes. As with all dragon lairs, the blue dragon's lair will have two entrances: one at ground level and hidden by the sand, and one opening onto a high ledge on which it can perch and survey its territory. Each lair also has a large subterranean cavern with a large pool of water and a sandy beach, which its inhabitant will use for drinking and relaxation.

Parenting and development
Despite their evil nature, blue dragons are actually excellent parents to their young, and will rarely leave their eggs unattended. Blue dragon eggs must be buried in warm sand to incubate. Blue wyrmlings are actually quite cute, but they are quick to taunt any other creature, and even quicker to hunt small desert creatures for food.
