Castrovel is a hot, humid world with a rich atmosphere that gives life to continent spanning jungles that are home to mobile carnivorous plants, saurian predators, and devastating moldstorms. While nearly every terrestrial biome can be found somewhere on Castrovel, the planet remains thoroughly wild despite its densely populated settlements, with modern cities and cutting-edge industrial complexes separated from the ravages of the primeval wilderness by electrified fences and automated weapons turrets.
The homeland of the lashuntas, Asana is the largest continent on Castrovel. It boasts everything from snowcapped mountains and sweltering jungles to rocky and rain-shadowed deserts. Its coastlines are for the most part mapped and understood, whereas records of the interior are largely confined to myth and broken history. In sharp contrast to their Lashunta neighbors’ dozens of competing city-states, the ant-like Formians of Castrovel have only one nation: a single vast country stretching from shore to shore across a continent to the south. This state has many names, depending on a particular formian’s region and beliefs, such as the Everlasting Queendoms, the Unified Hive, and the Glorious and Undeniable Dominion of All Beneath Moon and Soil. Most outsiders refer to it simply as the Colonies.
Few records suggest any large-scale
colonization of the isolated continent of Ukulam has ever taken
place. Its unconquered depths have remained the domain of
deadly plants, immense fungi, and powerful beasts that drive
a never-ending cycle of evolution, growth, and decay. These
inexorable processes ultimately consume settlements, leaving
most ruins damaged beyond easy identification.
