The countless worlds across the Astra share little in common -- different gods, different celestial bodies, and different magical phenomena cause any one person's experience to be wholly unique across the vast tapestry of the universe. The solitary thread that ties everyone and everything in the Astra together is magic.
Magic is pervasive in this universe and a fact of life everywhere, save one small planet near the galaxy's core. Until recently, Færrin was alone. No magic diffused the world, no gods walked the planet, and no stars lit its sky. It was, in a word, mundane.
For hundreds of thousands of years, the people of Færrin lived believing they were alone in the universe. As it turns out, life with the certainty that there's nothing out there is not much different than life with the certainty that there is. The Færrish people lived, died, built civilizations, and let them crumble in much the same way as anyone else anywhere else. Life happened, unfettered.
Before magic was introduced to Færrin, the only sentient life on the planet was human. Afterward, more than half of the humans found themselves taking on new traits, spurred by the sudden influx of magical energy. Magic beasts with sentience also appeared throughout the planet. Perhaps this is unimportant to modern life, but it's an interesting tidbit for researchers trying to find what encourages intelligence in the Astra.
The world of Færrin is the setting for this campaign.
