The world was once a vibrant and magical place. Oculodyine, originally a research and development megacorporation dedicated to the use of The Word and associated arcane sciences to improve the lives of the massess, became corrupted by the seductive lure of power, growing ever-more authoritarian even as they pushed past the boundaries of what was known - and, in the eyes of the Creator, what was acceptable.

Manufactories operated by the many experimental golems and magically-engineered life forms of The Authority churn out necessities with the veiled threat of denial should the public disobey, while state-maintained portals to the elemental realms provide meager air and water supplementation.   It falls to a new generation of rebels to rise above the arcane strictures of their society and finally finish what the heroes of old started: destroying the Shadow or casting back from whence it came...
