The "Humans of Ardum" are a fictional group of humans who have undergone magical transformations due to events called the Shattering and the Crystalline Emergence. These events irradiated the genetic code of the world's inhabitants through magic storms, causing them to rapidly evolve and adapt to their environments. This led to the development of various human subspecies and variants with distinct physical characteristics and adaptations.
The different groups of humans are located on different continents of Ardum and have adapted to their specific environments. For example, the inhabitants of Svalrund are large, strong, and resilient to cold, with high bone density, enlarged lungs and two hearts, and unique blue-tinged skin. The people of Vonitalle have adapted to extreme heat and toxic environments, with bodies capable of efficient heat dispersal and lungs capable of rapid detoxification, and they grow heat-resistant scales on their arms and hands. The Helberonians, from mountainous regions, are giants with dense skeletons, strong joints, and a natural ability to sense vibrations in stone. The inhabitants of Vastiaram are known for their high cranial capacity and dense neural connectivity, resulting in a physically frail but intellectually superior people with large eyes and a low emotional range. The people of Aethidd'nae have bodies with dense bones and large lungs inside their wide torsos that are adapted to endure strong winds and high altitudes, and they possess an innate sense of aerial currents. The inhabitants of Wacai are fluid and limber, with physical adaptations for aquatic environments.
