World 937, nicknamed "Rustidium" by the Celestial Cartography Guild is an example of a world where industrialization went horribly wrong. At some point a mix of tainted magic, pollution, and disease pushed the dominant civilizations into a resource rush, and then into global war. Biological, chemical, necromantic, druidic, robotic, and eventually "dirty" atomic warfare between Superpowers led to a massive collapse of several nations. Full-out atomic war followed, leaving a planet incapable of sustaining civilization at all.
Tainted by wild magic, roaming undead, lingering disease, and radiation, Rustidium would be the list of Forbidden Planets, but the Guild, at the urging of the Chaos Wizards has kept an observation station over the planet to let the world serve as an exemplar as to why certain technologies and magics are forbidden, even to the Godless.
Accordingly, many of its most significant threats are catalogue by the CCG to assess dangers to forays both on Rustidium and similar worlds.
