The Badlands used to be a bountiful area where a powerful theocracy ruled. The Old Faith was an order of powerful druids who believed they had a divine guidance to rule the land. As they grew more powerful, they attacked the layers of hell in order to eradicate them one layer at a time. As their power grew, so did their ambition.
A betrayal in the form of pact with the demons eradicated most of the upper order of druids, and the explosion of magic turned the land into a wasteland. Surprisingly, the hell creatures kept their promise and a demented druid of demonic lineage is in charge of the open portal to the demon lands. Because the lands was permeated with chaotic magic, wizards relocated to The Sharid and formed a democracy there.
