These cave-dwelling dragons are well-adapted to the darkness of their chosen homes... their hides glow brightly with bio-luminescent stripes, flecks, spots, and crystals. Their glowing hides are their greatest tools in everyday life, from helping them find their way, to hunting prey, to hiding within their caves to ambush enemies.

Many Copper Cave Dragons live the majority of their lives without ever leaving their cave systems at all, their labyrinths of tunnels, chambers, and underground lakes are so extensive. Clans in every part of Sornieth may have Copper Cave Dragons living beneath them without having any idea that they're there at all!

Skink and Spinner: Dragons with Skink or Spinner genes have developed stripes of bioluminescence (green along their bodies, though their wings may have different colors entirely) that they use not just to illuminate their way in the dark of their caves, but also to hunt prey inside their cave systems. They can use the stripes and spots on their hides as glowing lures; they particularly enjoy twitching their bright tails along a tunnel as a lure, and then pouncing on any unlucky creature who falls for the ruse.

Runes, Ghost, and Smirch: Cave dragons love to paint their caves, and themselves, with their own formulations of pigments, including glow in the dark pigments. Some clans paint their own bodies with mystic symbols or skeletal ceremonial paint, and others just... had a bit of an accident with their glowing pigment experiments. An exploding accident.
