The Life Essence of Dragons. Every Dragon, unrelated to its kind, is born with a Kripto embedded in its chest. Kriptos are the souls of dragons, holding unique arcane powers. Men and Dragons alike hunt these extraordinary gems for the powers they hold. Killing a dragon and ripping the gem from its chest traps its soul inside and is the only way a Kripto can be harvested. Only the bravest fighters have a chance of earning one of these rare gems.
