Ecosystem & Environment

The environment of Caelum is characteristically harsh by the standards of ground-dwelling peoples. At high altitude the air thins to a level that would leave most surface races gasping within minutes, a pressure to which Aeriel physiology has adapted over millennia through enlarged lung capacity, denser blood, and a resting metabolic rate that outpaces that of most humanoid races. Violent sky-storms periodically lash the islands with ferocious winds capable of stripping foliage, cracking stone, and hurling unsecured objects into the void below. The Aeriels have developed advanced weather-control technology precisely to mitigate these dangers and make high-altitude agriculture viable, though Caelum's capacity to produce food remains severely limited, necessitating significant imports of grain and other staples from surface civilizations.

The sky-islands of Caelum host an ecology found nowhere else in Landorya. Thin soils, sustained by windborne mineral dust and the slow decomposition of ancient enchanted bedrock, support hardy mosses, wind-grasses, and a class of root-anchored flowering plants whose blooms track the movement of the sun with mechanical precision. Certain varieties of sky-lichen colonise the undersides of islands and can be harvested for alchemical reagents of considerable value.

The weather-management systems that protect Caelum's agricultural plateaus are themselves ecological interventions — aeromantic pressure adjustments that redirect the worst storm-cells away from inhabited islands and toward open sky. This management is not without consequence: redirected storms have occasionally struck areas of the surface world below, and the diplomatic fallout from such incidents has periodically strained relations with ground-level civilizations. The Ministry of Celestial Affairs maintains ongoing meteorological records to refine the targeting of such deflections, but the fundamental tension between Caelum's survival needs and the welfare of the surface world below remains unresolved.
