The Prime Roots make up the most mysterious ecosystem on Atys. Delving into the bowels of the planet, this never-ending labyrinth of deep caverns can astound the curious eye with its remarkable beauty, blinding them to the danger that also lurks within. Sap flows here in endless rivers and fluorescent plants softly light the way for travelers, while strange creatures prowl about in the shadows. The Prime Roots are home to a host of mysterious relics from the past as well as a wide range of resources that can found nowhere else.
