Editing Gem Dragon (section)

===Obsidian Dragon===
Not one of the original five breeds of Gem Dragons, Obsidian Dragons were invented in 3rd edition as part of the Mind's Eye article series on the WotC website. These Gem Dragons are the most intelligent of their family, but also the most vicious; extremely haughty, easily angered and with a sadistic streak that manifests in a love of "toying" with their prey before finishing it off, their mandated alignment is Neutral Evil.

An obsidian dragon has smooth black skin with razor edges where joints come together. When first hatched, their scales are gray, rough to touch, and well defined. As they get older, the scales darken, become smoother, and begin to blend together. They have only the one breath weapon; a cone of fire, but they wield an array of innate psionics centered around telepathy and pyrokinesis. They also have the innate ability to [[Plane Shift]] at will between the [[Material Plane]] and the [[Inner Planes]], with great wyrms developing the ability to use the psionic power ''Genesis''. 

Most obsidian dragons prefer to make their lairs around volcanoes or in one of the mountains of coal found on the Elemental Plane of Fire. Most great wyrms, though, make use of the genesis power to create their own demiplane.
