Lore
Sulfur Vespers are bat-like aerial pests commonly found in geothermal regions, nesting around vents, caves, and unstable rock formations. They are highly aggressive and will swarm anything that enters their territory, relying on rapid flight and repeated dive attacks. While individually fragile, their numbers and erratic movement make them a constant hazard in certain zones.
These creatures are believed to have evolved from small flying mammals that adapted to geothermal environments. Prolonged exposure to sulfur gases altered their respiratory systems and heightened their aggression, allowing them to thrive where few predators can follow. Their rapid breeding cycles ensure infestations form quickly if left unchecked.
