Crystal wyrms are the race of true dragon who makes its home at the Plane of Earth.

Biology
Crystal wyrms are massive quadrupedal dragons made entirely out of rock. Their horns, teeth and claws are made out of crystal, and their eyes are made from precious gems. Various gemstones also grow across their entire bodies, which the dragon produces naturally. Their wing webbing is also made from large, pointed crystals, making them one of the only species of true dragon completely incapable of flight. Adult crystal wyrms reach over thirty meters in length, being among the largest of all dragons.

Ecology
Crystal wyrms inhabit the cavernous depths of the Plane of Earth, where they spend most of their time completely still, almost being mistaken for piles of rubble. When invoked into the material plane, they make their lairs in underground passages where ores are abundant.

Society
Crystal wyrms live solitary lives, though they are not intolerant to the presence of others of their own kind. They are calm and collected creatures by nature, being content to spend long periods of time in deep contemplation, ignoring all that does not directly concern them.

Abilities
As monolithic beasts made of solid stone, crystal wyrms are the toughest of all dragons, being able to shrug off blows that would greatly harm other species of true wyrm. Their breath weapon takes the form of a blast of crystal shards which can lacerate creatures of flesh and tear them apart without difficulty.
