Topaz dragons

Topaz dragons are erratic, antisocial gem dragons who are often selfish and disinterested in things that do not affect them. They prefer to live by beaches, and enjoy the feeling the sea wind against their faceted, yellow-orange scales.
Gem dragons are all inherently psionic creatures. They develop telepathic abilities shortly after hatching—sometimes even before—that grow in strength as they age. Some hone these mental powers further, manifesting

powerful magical abilities through their minds.
These psychically adept dragons often find themselves at odds with aberrations, particularly mind flayers and aboleths. The gem dragons are skilled at locating areas where the Far Realm intrudes upon the Material Plane and set themselves against the alien creatures spawned or twisted in such places.

Physical description

Often mistaken for the incredibly rare yellow dragons, topaz dragons share similar size and scales with these creatures. Their orange-yellow scales blend perfectly into deserts and strongly reflect the light of the sun, causing to be mistaken for a second sun on the occasion. 

Combat

Topaz dragons breathe a cone of dehydration. Topaz dragons dislike intruders, but avoid combat, often conversing to hide psionics or magic use. If intruders are hostile, or the dragon tires of them, it attacks, psionically first if possible, using spells as needed. They enjoy using teeth and claws, and usually save their breath weapon until wounded. The dragon may pretend to surrender to buy time, and retreats if greatly threatened. It usually makes one or more false retreats, attempting to come back and attack with surprise.

Lair

Gem dragons set themselves apart from the affairs of other beings, even their own kind. They search out lairs far from established populations which they can tend in solitude, or so they can carefully cultivate a circle of servants or vassals to tend their interests in the surrounding region.
Gem dragons break their natural inclination to solitude to mate and protect their clutches of eggs, but rarely for any other reason.
