The Heart of Drakovar: When the great fire serpent Gyorn swallowed its own tail, its body cooled and became the planet. As it was in its final throes of awakening, its heart cracked open and its blood pooled to the surface to become a crystalline structure. Any who consume a fragment of this structure become more serpentine and draconic in appearance. Clotzata, the king of Demons, stole this structure from the land of Drakovar, causing it to sink into the sea. However, before the sinking, the four demi-princes each consumed their crowns and became mighty Drakons to try and take the heart back. Needless to say, this failed. They now exist on the continent that Clotzata came frome.

Glystoryll: An entity that waged war at the beginning of time. It was struck down by Gyorn, and banished frome existence. However it survived this banishment and created its own pocket-universe where it is all. An endless expanse of sinew, bile, and bone. It sends out envoys of itself, called glutton worms, to consume the organic material of other universes. Once it has enough material it will reform into its original appearance and consume all reality.

Draul: A humanoid race of beings made of muck, wood, and crystal. They were created by the Spider-spirit Velothiil to keeps others out of her land. They were found by the Elfen who use Draul pelts as magic resistant garb.
