A vorwyrm is a great cosmic beast that is responsible for the creation and destruction of worlds, according to the mythology of the Inar. The process of creating and destroying worlds is called the Vordragon Cycle. The hatching of a vordragon is caused by the burrowing of an elder vordragon which has become a vorwyrm as a result of doing battle with its hatcher. After consuming sufficient vorsys, the vorwyrm goes on to consume the worlds and form a new vordragon egg.
Hatching a Vordragon
The world of Galwyndor was created when the vorwyrm known as Dekilia burrowed within the cosmic stone that housed the egg of the vordragon Gyva. In cracking the egg's shell, the new vordragon hatched, shattering the stone and the shell in a great burst of fire and smoke. This dispersed the stone pieces into the cosmos, creating worlds. Embers of the flame also spread, forming suns and stars. Pieces of the shell also rained down upon the newly created worlds, which were rich with gleam the energy that could create new life.
Cosmic Battle
Gyva, being young, was full of magical energy called vorsys, which the elder Dekilia sought, as it had just fought a long and terrible battle with the vorwyrm that hatched it. Dekilia coiled around the younger and attacked it, trying to leech some of its energy for itself. A great cosmic battle ensued, with both creatures fiercely fighting to gain control of the vorsys energies. Tears from the younger dragon fell to the earth to become the water. Gyva's shrieks and the beating of her wings created the air. Having no wings or legs, only a maw, the wyrm Dekilia could only bite, squeeze, and bleed. Dekilia's blood fell to the earth, scorched from the flames the younger dragon belched forth. While locked in battle, the elder began siphoning power.
To get power quickly, the vorwyrm consumed the limbs and wings of the younger vordragon, where it would then have enough strength to overpower the other dragon. When enough power was leeched, the elder released its grip on the younger. In defeat, Gyva retreated to seek solace within a new cosmic stone that housed a fresh vordragon egg, where it would burrow to seek out new vorsys with which to restore itself.
Death of the Vorwyrm
Now restored with new vorsys energy, Dekilia would begin consuming the worlds and suns dispersed by the battle to regain all the vorsys lost. Once it had consumed everything, it would surround itself in a sheath of stone, which would be its tomb where the wyrm would die. This death would in turn form a new egg that would gestate inside the stone until released by a new burrowing vorwyrm, which would begin the cycle anew.
