This breed of dragon was thought to exist only in legend. Although their name varies between cultures, they are often referred to as “Guardians of Nature.” They are able to channel the forces of fire, ice and lightning, which allows them to wield tremendous power. Seen very rarely, it is thought that they only become active when something is threatening the territory they have chosen to guard. In order to protect their chosen home, these dragons are incredibly adaptable; they have been seen everywhere from remote mountain ranges, to ancient forests, to the darkest depths of the ocean.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

The Ancients knew that in the future, the cave will be in great peril. In an attempt to warn the cave, they gave a prophecy:

Disturb not the harmony of fire, ice or lightning, lest these titans wreak destruction upon the world in which they clash. Though the cave's great guardian shall arise to quell the fighting, alone its song will fail, and thus the earth shall turn to ash.

During the dragon war of the elements, an egg was formed in the midst of the fighting. The current elders believe that this egg, that XDLugia, is the cave's great guardian. If that is true, XDLugia is prepared to face the end. He hopes that if he can't stop the destruction of the cave, his passing will.
