In year 247 of the Dawn Era, a primordial that relinquished the Primordial Mandate to focus on creation constructed the inaugural world of the Arborea System. Until the advent of the God Era, the worlds of Arborea, all crafted by the Prime Architect, remained unrefined and unsettled, with ferocious beasts reigning as apex predators. Indeed, the legendary creatures that manage to traverse to distant realms, whether through rift or summoning, trace their origins to the worlds of Arborea. It is believed that Arborea alone possesses the optimal Energy Composition capable of spawning such entities.
The Arborea System comprises three distinct worlds: Arvandor, Aquallor, and Mithardir. Arvandor, often referred to as the elven realm of Arborea, boasts lush, deep forests that serve as the celestial domain of wood elves, as well as more diverse landscapes suited for other beings (excluding the souls of Drow, which typically end up in the Abyss). This world also features vast expanses of spires and mountains, catering to those with the ability to take flight. Aquallor, the water realm, is a sprawling landscape of endless rivers winding through lands of lakes, ponds, and great oceans. The final world, Mithardir, is a forest-covered realm serving as the home to multitudes of fey and beasts of every size.
