In the very center of the world is a giant storm, a swirling vertical column of aetheric energy known as the Nexxus. Though dangerous, this storm can be entered through various means, and to those skilled enough to navigate it, another world beyond can be entered. The Asharen were the first to successfully explore the Vortex with flute ships. What was discovered was a strange world on the other side which was filled with two flowing forms of energy, the Aethereal Sky and the Nethereal Sea. Many riches and unusual resources have been uncovered, and this strange new realm is now the object of exploration and expansion for all of the cultures of the world. One town in particular, Netherdown, has become the central hub for launching expeditions.
